Hello, I have a 4xgreat grandfather named Philipp Ahlheim. I know this because I know for sure that my 3xgreat grandfather was John Peter Ahlheim (1860-1920). And I found a marriage certificate between John Peter and my great-grandmother, that lists John Peter's parents as Philipp Ahlheim and Elisabeth Klein. Through other people's family tree, for the longest time I thought John Peter's father was Philipp George Ahlheim, son of Thomas Ahlheim and Elizabethe Margaretha Daab. Thus, I have a lot of information on Elizabethe Margaretha Daab's family line in particular (if needed); I have all the way back to what I thought was my 17th, 18th, 19th great-grandparents.
But, it has come to light that this may not be true. My grandmother's cousin thinks that his father's name is Philipp Peter Ahlheim. But I am having so much trouble with this name. I can't find anything. Please Help!
