My relationship calculator in my RootsMagic software tells me that Jacob is my:
1st cousin 3 times removed through Jacob Yoder & Mary Keim
3rd cousin 3 times removed through John (Hans) Reichenbach & Anna Rupp
4th cousin 3 times removed through Heinrich "Henry" Reichenbach & Barbara Thommen
The first one is, of course, the closest connection. His father Jonathan Yoder and my great great grandmother Barbara Yoder Lantz were siblings. Their parents were Jacob Yoder and Mary Keim.
Now, I'll try to explain the two through the Reichenbachs. I am descended through three different children of of Heinrich "Henry" Reichenbach and his wife Barbara. I suspect that this Jacob Yoder had multiple connections to the ancestor as well. That's why it is showing up multiple times and skips the generation of John Yoder and Barbara Reichenbach (the parents of Jacob Yoder, spouse of Mary Keim). We ended up having multiple relationships through some of these individuals.
