Somehow I don't think we are of the same branch of the Mitchells. My grandmother was a Mitchell, daughter of William Mitchell (wife Agnes
Miller) a headmaster in
Irvine in Ayrshire. I have traced this branch back and found an American relative, John Mitchell of Kendallville,
Indiana and he was a grandson of an Andrew Mitchell, who emigrated to
America from Clawfin in Ayrshire in 1753. This branch is traceable back to Andrew Mitchell born in 1654, just about when records began here. No trace of any Gibsons, however. I doubt if this is what you are looking for, however. Let me know if I can help further. Dorothy
