No, I don't have any information about Hiram but would love to know more. Apparently from another of your posts, there was a family migration through Tennessee to Illinois with the Foster Family? Where from and when?
I am looking for the parents and siblings of a G.A. Fann born 4/9/1822. I wonder if Hiram's son George could fit that bill. Do you know his middle name? G.A. lived in Cannon County, Tennessee for much of his life, marrying there in 1844. He went by "Grundy", but that sounds more like a nickname to me.
Any info you have about Hiram and his children, and where they were spread during this migration would be very interesting.
