I think there is an error in the connections here. These are my son's paternal relatives and I've been working on his Bohannon DNA matches on Ancestry this past week.
Notice that Anna's husband Elijah's mother was Anne (Bohannon) Kirtley. That Anne's parents were the Elliott Bohannon and Ann Walker connected here as this Anna's parents.
I think this Anna must have other parents. All the Bohannons in the connections made here are from Virginia and only this Anna shows being born in Pennsylvania and dying in Ohio, so her geography doesn't fit for these connections. Even her husband died in Kentucky.
The tree of the DNA match for my son has this Elijah Kirtley as:
Birth : 9 Nov. 1820, Boone Co Ky
Death: Feb. 1860, Henry Co. Mo.
and has his wife as
Mary Sanford
Birth: 9 Nov. 1820, Boone Co Ky
Death: Feb. 1860, Henry Co. Mo.
which fits with where Elijah was.
Just sharing what the tree of the DNA match has and what I know of the lines since my son is a descendant of the Bohannon / Kirtley lines.
