- Jesse Runyan was born about 1863 in , , IN, USA.
It is Jesse and Phebe's daughter Mary Jane that I'm descended from. Since she and her mother both have the middle name Jane, I'd say it was the first name of a woman in the Cooper family.
I almost forgot an important technique. It can be very rewarding to do cluster genealogy, to study other members of the family. It can lead you to other sources of information that will ultimately provide the information you're looking for.
