Frank Nelson & Maria Nikula were actually my great grandparents. Their son I think, was Alfred Nelson who married Sylvia Piiispanen, and they had one child, my dad in 1909 in Quincy.
Frank and Alfred may be brothers, I'm just not sure.
There is also Hjalmar Nelson and his wife Selma ?
and they are connected to Frank and Alfred as well, and living in W Quincy at least in the early 1940's.
