Samuel had two sons, Joseph and Abraham in the 1740's (in New Jersey)
Joseph had a son, Levi
Abraham had a son, Levi
One of these (Levi) sons has no further history, the other Levi married and had at least 9 children of which there are many descendants today.
The problem is that the descendants of these 9 children of Levi can't determine if "their" Levi is the son of Joseph or Abraham.
Is there any way that genetic genealogy can help resolve this?
