We can only guess at John's middle initial. Could be S from my aunt's notes. Census records just John Cunningham.
Other brothers:
Joseph O.
James P.
Francis Franklin

Documented Union:
William H.
Prior Essex
Calvin Jones

We surmise that John had one too, but we don't exactly know.
Franklin L. is probably related, but don't know how. I may or may not have looked at the veteran's 1890 census. I can't remember. I have looked thru the pension records and could find nothing to help me.
All men survived except Mordicia, the father, that died in 1863.

Thanks,
