I'm surprised I just saw this, ... I am a distance cousin of yours.
If I understand it right, Christian had a brother named Jacob who would be my Great-Great-Great grandfather.
I just started working on my family tree and found a lot of the heavy lifting was already done by by people working on other branches that intersected with the Ehmer line.
I would love to hear more about your family. This posted added a lot of info I was not aware of. BTW, I live close to Negundo Ave in Flushing/Fresh Meadows. :)
