Is it: Neu-angelegter historisch genealogischer Palm-Wald ?
Medieval Lands? NOPE
Wikitree? NOPE?
geneanet-pierfit? NOPE
geneanet-rodolfoweber? NOPE (and this is one of the few from geneanet that go past Dietrich)
I have to wonder how accurate this is, based on the fact that I see no other genealogical trees elsewhere that have his father as Konrad. Yes, this is an AI/ChatGPT attitude, but in this line of inquiry, where it's better to have nothing than have a false genealogy, it's best to be safe.
Also, it should be noted that the Dutch seem to have a thing with false genealogies being recreated in the 1600s.
