I have a photo of Abisha's headstone and of his daughter, Matilda Ann Wilson Glover, but would love to know what other photos of the family you have. My husband is the grandson of Matilda.
Abisha is the son of William Wilson Jr. and an unknown Miss Camp. Here are some notes I've collected which might help.
