I am doing some research on the Elofson family. My great grandfather was Robert Elofson Sr and I am trying to find who his father was. On the 1900 census, Robert E lived with Nels Elofson and was listed as a nephew. I found Peter(Pehr) Elofson, Nels Elofson's brother and am wondering if Robert E could have been his son, as he is the only brother I saw. Any information at all would be useful.
