My great grandfather was John Fane, who died in 1871 at the age of 45, in Dixon IL. He came from Ireland around, or shortly after, 1850 to New York State. He married Johanna Mullen/Mullin/McMullen. They had their first children in upper state NY, then moved to Dixon IL. Their children were Mary Ellen, Daniel, Patrick, Margaret, John, William, Timothy, Johanna. I am trying to determine John Fane's roots in Ireland.
