Here's the situation: I have strong documentation going back to a Fanny Bergey, born 11 April 1794. (Maybe 13 April.) And, I have 41 DNA matches through that ancestor but no direct evidence of which Bergey (or Berge or Bergy) family she comes from.
Some trees have Johannes "John" Berge (or Birki or Bergey) as her father, but: records show no "Fanny" or "Veronica" in that family, and not only no daughter of the right age but a son born in July 1794:
So, I'd ruled that out. However... here's what AncestryDNA is showing:
... that is, lots of matches for those other Bergey siblings!
What does this actually mean?
There aren't any other Bergeys elsewhere in the tree — there's a "Berkey" in another branch, but further back and not apparently closely related to this family.
What are the possibilities?
Additional information: there is a Bergey genealogy book, and I can't find any reasonable candidates among cousins and siblings, either.
