I recently discovered that my great grandfather, born in Mazowieckie province, Poland, had German ancestry through his mother. Her family first settled in Łódź province from Germany in the early 19th century. I found several trees on Ancestry.com and Geneanet which trace my great great grandmother's line (her maiden name was Dyngiel) through the Kleinholtz, Bast, Dhom, Rheim, von der Heyden, von Gymnich, and other families to Henry II of Nassau, who seems to be a descendant of Charlemagne. These trees have dates and places, but I have not seen, so far, any primary sources for them. Some time ago, there was a post in this group which mentioned a number of sites which could potentially be used to verify some medieval lines, for example Genealogics.org. Thanks!
I'm not sure what is meant by "Henry II of Nassau ... seems to be a
descendant of Charlemagne", but assuming that "seems to be" is a way of
saying "may be" then it is correct.
The early generations of the Nassau lineage are the subject of perpetual
guesswork. As this was the male line of the royal family of the
Netherlands, much ink flowed over it in the 19th and century and later.
Henry II's father Walram I is actually the first member of the line from
whom descent can be fully proved from reliable sources. Leo van de Pas
in Genealogics followed a reconstruction by Isenburg as reprinted in the
1975 revision of the first /Europäische Stammtafeln/ series - this may
have been among Leo's earliest work, and he evidently did not get round
to checking it against the more recent version by Schwennicke in /neue
Folge/ vol. I.1 (1998) where the conjectural parentage of Walram I is
indicated by a broken line.
A documented descent from Charlemagne to Henry II depends on whether or
not Walram I's paternal grandmother was actually Beatrix of Limburg, and
however probable this seems it remains uncertain.
