How have you done on your Buehler family tree? I have just started on my husband's tree and his great grandparents are Adam and Alma. His grandmother was Anna M and I think she was related to your grandfather Otto. On a family tree from my husband's aunt, we have the parents of both Adam and Alma, but haven't gone any further back. As I said, I'm just starting on his tree. If you can be of any help..... that would be great.
thank you,
Donna
