being Homo

I have been reporting on progress into genetic studies of human evolution ever since Svante Pääbo's group published the first glimpses of the Neanderthal genome. Less frequently I have also ventured deeper into time, where morphology is the only handle we have to try and draw up a family tree of our evolutionary ancestors. The categorisation of some ancient fossils as Homo while others are filed in other, extinct genera, has always struck me as illogical and confusing. So I was very glad when I stumbled across a new paper that calls for a revision (and expansion) of our genus. That was a good enough excuse to write another feature about human evolution, which is out now:

Homo erectus was a hominin species that thrived for nearly two million years across three continents. Proteomic studies suggest that this species may be the source of ‘super-archaic’ gene variants inherited by modern humans via Denisovans. (Photo: Emöke Dénes/Wikimedia Commons (CC BY-SA 4.0).)

a 200th wedding anniversary

Tomorrow (21.9.2026) will be the 200th wedding anniversary of the founding couple of my Krefeld Clan:

Wilhelm Düselmann * 13. 8.1804 Krefeld + 17.12.1865 Krefeld

and

Elisabetha de la Strada * 17.12.1804 Krefeld + 15.12.1882 Krefeld.

I blogged a list of the descendants we knew back in 2009 in one of my first blog entries on family history, and this has led to to additional information (we now know of 13 children, with the girls brought up catholic and the boys protestant to reflect the different confessions of the parents, 32 grandchildren, and hundreds of fascinating people further down the line) as well as to real life meetups with several relatives I was previously unaware of, so this wedding held in Krefeld 200 years ago is a bit special. I was slightly tempted to try and organise a family event for the occasion, but that would have required actual people skills which I don't have so I'll just commemorate the day with another blog entry.

Sadly we don't have photos of bride nor groom, although both lived long enough to suggest they may have had a portrait taken in their old age. Incidentally, the oldest surviving photographs made by Nicéphore Niépce date from 1826 as well. A wedding photo or our couple would have looked interesting, because the first of the 13 children was born eight weeks and two days after the wedding, on 18.11.1826.

What we have is the actual marriage certificate:

Photo of a photocopy of what appears to be the original marriage entry in the archives of the town, with the signatures of the newlyweds and their witnesses, and surviving parents. First we have what must be the presiding official. Then, in larger handwriting, Margaretha Düselmann (nee Wilsberg, mother of the groom), Wilhelm Düselmann (groom), Hermann Düselmann (brother of the groom, born 1798), Elisabetha Delastrata (bride), then in the bottom line Heinrich Siecher (?) or something similar, who allegedly was a brother in law of the bride but I don't have a matching name on my records. And the last name I can't decipher at all. Even though the mother of the bride, Margaretha de la Strada (nee Giesen) was present as well so should have signed.

The fathers of both families had died a few years before the wedding. Note also that Elisabetha's older sister Maria Catharina de la Strada married Jacob Joseph Nolden at the same time.

I've blogged about Krefeld as one of my "lost cities" here (although it is not quite lost, some distant relatives still live there).

Further revelations relating to the Krefeld Clan are tagged #düsselmann.

the vicar of Eckweiler and his family

After I discovered so many clergymen in the family network around Johannes Weiß (see the preliminary list at the bottom of this blog entry), I had another look at his biography and at what became of his children. Note that his wife is at the core of a matrilinear transmission of Pfarrhaus (vicarage) traditions, so she becomes a co-headliner.

So here comes a revised and updated version of the biography (replacing the one in this blog entry, which was basically a transfer of an ancient page from my old website when it went offline).

 


 

Johannes Weiß (1704-1772) and Katharina Elisabeth Ebner (1712-1790)

Johannes Weiß was born on 29.9.1704 at Königsberg (near Wetzlar, today Hessen) as the son of the merchant Johann Justus Weiss (ca.1675-1740) from Silesia and Maria Elisabeth Straus from Königsberg. His confirmation was at Seibersbach (Hunsrück) in 1717, which suggests there may have been family connections to that area where he later worked. He studied theology at Gießen and came as a parson-in-training (Pfarrkandidat) to Dörrebach near Seibersbach. There he was appointed a vicar in 1729. The job also included the parish of Seibersbach, and I understand that the vicar had to live in the Pfarrhaus at Seibersbach as the one in Dörrebach had been usurped by the Catholics since 1703.

In 1732, while serving at Dörrebach/Seibersbach , Johannes married Katharina Elisabeth Ebener or Ebner, born at Trarbach in 1712, the daughter of the vicar of Alterkülz (Hunsrück), Philipp Ebener (~1681-1734). Previously (from 1708 to 1720), Philipp had been a teacher at the Lateinschule in Trarbach, like his father before him, see my biographies of Ebner father and son here. A potted history of Trarbach and the Lateinschule is here. So Katharina Elisabeth Ebenerlived at Trarbach for the first eight years of her life. With three university-educated men in her immediate ancestry, and many more in the extended family (including the illustrious Arnoldi clan), she had a Pfarrhaus background while her husband was a newcomer in this scene. Considering this imbalance, I would suspect that her family picked him on the grounds that he was an eligible Sponheim vicar who wasn't a blood relative.

Johannes and Elisabeth had seven children that we know of, with the first five born at Dörrebach/Seibersbach between 1734 and 1739. See the list of their descendants below.

The church of Eckweiler, the only building left standing of the historic village. In 1979, the village was officially dissolved. Following the introduction of Phantom fighter jets on the nearby airfield of the Bundeswehr, the noise had become unbearable. The last 250 villagers were relocated to a brand new suburb of the nearby town of Sobernheim, and all buildings except for the church -- not the original building, but the same location where Johannes had held his service some 250 years earlier -- were demolished. Too hastily, as it turned out, as the end of the cold war also saw the Bundeswehr selling off the airfield to a car manufacturer who planned to use it as a test course, but never did. So Eckweiler, known locally as “the church without a village” is very nice and quiet nowadays.

In May 1740 (according to the Eckweiler book, the Weiß Chronicles claim it was 1742), he moved to become the vicar of Eckweiler (some 20 km deeper into the Hunsrück), where he remained in office until his death in 1772. In fact, one of his great-grandsons wrote the Weiß Chronicles in that very same village nearly 120 years later.

The last two children we know of were born at Eckweiler in 1742 and 1751. Seeing that their mother only turned 30 in 1742, there may have been children in that interval who didn't survive?

According to the Eckweiler book, Johannes Weiß was a very assertive type of person, who would always make sure that everybody got their due. In first years of his 32-year tenure, he had the church renovated inside and out. His lasting legacy, however, was to be the village school, built in 1770. Documents relating to the funding for the school house reveal that Eckweiler at the time was the poorest parish in the district.

According to the same book, Eckweiler had 157 inhabitants in 1769, all of whom were protestants. Johannes’s parsonage also extended to the neighbouring village of Daubach, with 80 inhabitants including 36 protestants.

Johannes Weiß died on 4.1.1772 aged 67. In 1773, his son in law, Philipp Bauer, was installed as his successor.

His widow continued to live at Eckweiler with her daughter and son in law. She died there on 1.8.1790 aged 78 (or just under).

In 1818, Philipp Bauer was the first vicar of Eckweiler to retire from the position, as he was deemed unfit to carry on at age 85. He died later the same year. Note, however, that according to this Gedbas entry he only lived to age 83 (however, that entry doesn't know about his marriage, so it may not be a reliable source). All vicars of the parish are listed here.

The next generation(s):

1. Christian Weiß * 1734 died 1754 while a student at university.

2. Johannetha Weiß * 1735 married a forester named Federkeil, at Gebroth (Hunsrück). Familysearch offers a plausible match in Johann Andreas Federkeuel who married Johannetta NN, with a son Johann Christian Federkeuel born in Gebroth in 1761.

3. Johann Gottlieb Weiß * 1736 the future mayor of Pferdsfeld. He married Anna Katharina Andrae from Gebroth, who turned out to have lots of clergymen in her ancestry (as well as a brother who studied theology). Funny that the author of our Weiß Chronicles (WC) showed no curiosity in her ancestry and doesn't even mention her parents. She was his grandmother! According to this Gedbas entry, Johann Gottlieb was also a teacher and a distiller of brandy. A separate blog entry about him and his family will go live next week.

4. Regina Catharina Weiß * 1738 married a Mr Weimar from Dörrebach. There are a few Weimar / Weymar families in that village listed in Gedbas to the extent that in there was a wedding when bride and groom bore that name in different spellings. One suitable candidate who isn't otherwise married would be Valentin Weimar the elder, who had a daughter Johannetta born 1766 Dörrebach, who then went on to marry Valentin Weimar junior and had at least nine children with him.

5. Maria Anna Dorothea (WC: Marianne) Weiß * 1739 married Johann Georg (WC: Philipp) Orth from Weiler near Martinstein, on the river Nahe. He is number IX-59 in the Orth genealogy, to which we also have connections here. They have six children and 17 grandchildren according to the Orth page. Four of the children died before reaching school age, only two sons survived and got married:
Philipp Georg, * Weiler 31.1.1760, + …, ∞ Weiler 24.2.1784 Catharina Elisabeth Keip (Geib) from Staudernheim, 7 children; only one marriage and no grandchildren reported.
Andreas, * Weiler 16.1.1763, + Weiler. 14.10.1839, church elder. ∞ Weiler … 1787 Maria Elisabeth Waldmann, * Weiler 8.4.1770, + ebd. 20.12.1842, 10 children, only three marriages (two daughters to the same man) and four grandchildren reported.
Although these families don't seem to be doing very well, I have been contacted (separately) by two people counting Maria Anna Dorothea Weiß as their ancestor, so some people did make it through the hard times.

6. Maria Elisabetha Weiß * 1742 married Philipp Jakob Bauer, a vicar at Enkirch, who later took over the position of his father-in-law at Eckweiler. Two children were born 1773 and 1781 but died in infancy. Maria died in 1819.

7. Philipp Theodor Weiß * 1751 became a private tutor for the counts of Solms, he drowned while hunting wild ducks in the back waters of the river Rhine, according to the WC. The church records of Pfalzdorf, the colony of thwarted emigrants where his aunt Anna Maria Ebner and her husband Carl Morlang (1720-1799) had settled, note that he served with the family Bilgen at Schmithausen castle (Kleve district) when he drowned on 2.1.1777. No mention of ducks there. Ironically, his employer, Geheimrat Casimir Bilgen, was appointed by Frederic the Great as the administrator in charge of the water regulation and dyke construction on the Lower Rhine.

Thus, it appears that all three sons may have studied to follow in their father's footsteps, but two died young and the surviving one only became a teacher and mayor. Of the four daughters, one married a vicar, one married a descendant of the Orth family which includes lots of clergymen in earlier times, and the other two appear to have stepped out of the circle of clergymen marrying each other's daughters, although we're not sure what Mr Weimar's profession was.

Thus we can clearly see the ambition to carry on the Lutheran Pfarrhaus tradition, which was quite possibly her idea rather than his, but the family suffered a series of misfortunes which led to the tradition dying out in this branch.

a Bloomsbury collection

I've long been a fan of the Bloomsbury group simply based on the very amazing book by Virginia Nicholson, Among the Bohemians, which I read and reviewed in 2009. Later I also bought a big photo book about Charleston and watched the movie Carrington. And read a book about the actual neighbourhood of Bloomsbury. Five years ago, I read The hours and blogged about the Bloomsbury set on that occasion. I guess what I love about the group is that it is like a big family of intellectuals, with everybody writing about everybody else, and a lot of the later material about Bloomsbury has been written by children and grandchildren of the original group, so it works a lot like family history on a celebrity level.

Now I picked up around ten Bloomsbury-related books from neighbours clearing out stuff, so my collection now looks like this (minus the actual Book of Bloomsbury, which went into hiding as I was rounding up books for the photo):

Own photo.

So I'm now in the process of establishing a dedicated Bloomsbury shelf. Might even read one or two of the new acquisitions. Watch this space.

PS: I've now applied the new tag #bloomsbury to everything related to the group and/or the place (six entries so far). This has become necessary as I appear to have reviewed quite a few books published by Bloomsbury, so the search function yields a mixture of both kinds of entries.

the people of the echoing valley

In a letter about the discovery of the Weiß Chronicles, Johanna wrote that the teacher Christian Gottlieb Weiß (1782-1867) had his first teaching job in "Höllenthal" - which would suggest the etymological interpretation as "Hell's Valley". I had always assumed that this was the historic name of the village now known as Hellenthal (Eifel), but Wikipedia seems to think it's got nothing to do with hell, and that it's all about the Hall you hear in the valley, ie the echo (Old High German hellan, to sound, resonate). As there was a lot of mining and metalworking in the area, the valley may have been echoing with the clanging of hammers and anvils.

Anyhow, Christian Gottlieb, who is also the earliest born ancestor of whom we have a photo, found himself a wife at Hellenthal. In 1806, he married Anna Gertraud Käuer, (1777-1858; alternative spelling: Keuert), whose ancestry is solidly from that village. Coming out of the Weiß family that is crawling with clergymen (up to 13 among his direct ancestors, many more in the extended family), he is the first in our lineage to leave that tradition behind and marry somebody with no church family background whatsoever. Also, he married outside the (former) Sponheim territory, where the whole clergy marriage network operated. And she was four years older than him.

Back in the noughties, my father hired a professional genealogist to look into the Hellenthal ancestry. He drew up a report on Anna Gertraud's family and found 14 of her 16 great-grandparents. No academics in sight but a few metalworkers. And a very tightly knit community where the family names like Vader(s), Pieroth and Bastert occur in duplicate in the generation of the great-grandparents. I was reminded of that fact when I updated my list of family names recently, so am now looking into the Hellenthal family tree again in the hope of discovering common ancestry for those pairs of great-grandparents sharing a surname.

My scan of a tourism brochure from the 1990s.

So here comes a little family tree for Anna Gertraud:

1. Anna Gertrude Keuert (Kauer) * 8. 3.1778 Hellenthal; ~ Gemünd + 7. 4.1858 Simmern u. Dhaun (80)

40. Thonnes Dreßen * Bronsfeld near Schleiden (recorded as a godfather in 1671)

56. ?Paul Pyroth (seeing that 28. was referred to as Paul Pyroth Junior?)

Note that there is a family tree on familysearch which is much less complete and deviates in the paternal grandparents and their parents. They also have a wrong year of birth and death for 2. Tilmanus - according to them he would have been 9 years old at the birth of his daughter. My guess is they picked another person also called Tilmanus Keuer and thus ended up with a different set of ancestors on the paternal side. So I guess we can safely ignore that dataset.

 


 

A few leads for further investigations:

Bastert (yes, the name means exactly what you think): There is a Pastert ironworks tradition in this area, see for instance Peter Pastert (1641-1728) in Schleiden (northern neighbour of Hellenthal). Also, a Bastardt family near Schleiden has been involved in a long running inheritance dispute in 1618-1628.

Pyroth / Pierot: The spelling varies wildly, but our genealogist and others have speculated that these people go back to a francophone lineage of Pierrot (derived from Pierre, the French version of Peter). As Hellenthal is a mining and metalworking town, this name could be from migrating miners coming in from Wallonia. We have some of these elsewhere too, eg in Fachbach.

Vaders: The genealogist said there were several Vader families in the previous generation and he couldn't establish a specific connection to any of them. There are seven GedBas entries for a (Peter) Reinhard Vaders born Hellenthal around 1635 who in 1674 married Anna Magdalena Lang from Neunkirchen (Saar) and moved there, producing lots of Vaders descendants. Seeing that he was around 40 at the time of this marriage, he could very well have had a previous family at Hellenthal, from which 17. Gertrud or 31. Maria Vader could be his children. Or his nieces. His parents were Franz Vaders and Evgen NN. All the Gedbas profiles seem to come from Saarland descendents not too interested in Hellenthal, so this trace goes cold very quickly.

another old violin's tale

Some thoughts on

The Violin Maker’s Secret
Evie Woods
Harper Collins 2026

Bookshop.org

Last year I read an old (1914) novel about a fictional Stradivarius violin following the fates of real and fictional players through the centuries of its lifetime. The author of that very romantic romp hiding behind a male pseudonym was Anna von Bonin (1856-1933).

Now I discovered a modern equivalent in the novel by Evie Woods (120 years younger than Anna von Bonin). It is a similarly wild romantic romp, but thankfully this time the violin is not a Stradivarius. It was made by a fictional Irish luthier called William Rathbone who died in 1841. He allegedly learned the craft from Thomas Perry (1738-1818) and knew Niccolo Paganini (1782-1840). Again, we're getting a mix of historic and fictional people through the two centuries of the violin's lifetime (1817-2025). There is a fantasy element in that the soul of the luthier's tragically deceased fiancee appears to have entered the violin, speaks to us as the voice of the instrument, and seems to have a magical influence on the romantic lives of the people who come near it.

Most of the plot is set in the present day (2025), however, with dramatic events unfolding after criminals steal the violin from an auction house but leave it at Heathrow airport where a baggage handler finds it and takes it home. A lot of the novel is also about personal baggage, so the protagonist's job is kind of an early hint to where we're going.

I've read this fairly swiftly and enjoyed it thanks to the subject matter matching my current interest in lutherie. I also happen to agree with the romantic statement being made here that string instruments can change lives (magically or otherwise) - can happen to all of us. I would also consider the author's earlier work The lost bookshop, for similar reasons (is it nominative determinism that she's drawn to objects made from trees?), but might skip the one about a bakery.

PS Among the real life violins / violinists mentioned in the novel we find Min Kym and the Stradivarius that was stolen outside Euston Station in London a few years ago.

languages: the rise and fall

Languages evolve, diversify and become extinct, so they count as biology, right? A recent paper modelling the rise and fall of language diversity gave me a welcome excuse to revisit languages from an evolutionary perspective:

naming names

Reading (most of) a book about German family names I got inspired to update the list of names I had left unattended in the depths of my family history file for many years. The version I started from had 162 names, and the one I ended up with now (see this page) has 326 names, so yes, it's been neglected for too long.

Some of the most common German surnames.
Source: RossiLeone, Wikimedia Commons.

To give a rough indication of how close or distant in history these names are, I included the Kekule number of the last carrier (except for the immediate family up to the generation of my grandparents). By default, these carriers are all women. There are only a couple of cases where a male line took on a new name (eg after marrying into a farm and adopting the name of the farm, see Wolff). I've ignored the previous names in these cases as we typically don't know much about them. Similarly, I have also ignored the (speculative) previous life of Johann Dopheide, who may or may not have been identical with Jean d'Oppède. If he was, the family tree wins dozens of additional ancestors in the French nobility going back to the crusades, but that would be an entirely different story to the rest of my family history, so I'm tending to ignore that.

After adding the numbers for multiple occurrences of the same name, we end up with around 375 name lines ending in a woman, or 375 female ancestors whose maiden name we know. There are probably as many with only a first name and no known family name, and many more males, so these named women are a minority and it was an interesting experience to go through the list and acknowledge their existence one by one by copying over their number into the names list.

I also spotted quite a few cases where the same name occurs several times in the same geographic area without being a very common name like Schmidt or Mayer. I am planning to look at these cases again to find out if I can find evidence of shared ancestry between the women sharing those names.

The page serves as an index to blog entries where I have explored the origins of specific names (like eg Bitsch) and/or the biographies of several generations in an extended name line.
