Re: 1910. Should be him. Age noted seems to be slightly off from an 1875 birth date. Children's names are correct. Believe there was at least one more. Wife's name different from what I'd been told. Unless there was another marriage in there somewhere.
Samuel would seem to fit. Marriage place of "Washington" has me wondering. If referencing the State, would have been Oregon Territory in 1861. And fairly early in the settlement process. Could this be Washington, Indiana?
This is fascinating. After so many years of wondering!
