I think your Barto E Doty is the son of Henry S Doty and Mary (Doty). He has sisters Josephine and Mabel, and a brother Ralph. (Mabel is my gg).
Interestingly, I THINK Henry S Doty was a 1st Lieutenant in a Minnesota regiment (or maybe the Illinois 52nd Infantry -- will take some more digging) in the Civil War, and his Captain's name was Alphonso Barto -- did he name his eldest after his commanding officer?
My sister-in-law has a photo of him with his mom and sibs.
