I am William D. Hanrahan, son of William F. Hanrahan, whose father also, William, came from Galway in Ireland. He was one of 13 children. So my, grandapa, William was born in 1882 to a Michael and Anne /Goode. William came to NYC in 1903 or 1913 and lived on 16 street in Brooklyn until the early 1950's when he passed. William Hanrahan from Galway married Anne Sharkey and had 3 children. William, my dad, Marion, just passed 12/2013 and Joseph.
I located the family farm, but right now I can't find my records, I know it is in Ballinasloe, Galway (Garryard,Killimor Ballinasloe, Galway) and I know there was a Mary Hanrahan married to, of course, a Hanrahan, but I am not sure of his first name either Thomas or Padrig. My daughter went there to the farm in about, 2003.
One thing I am very sure about is that Gilmore in Montana was my father's cousin. They had a son who became Bishop Gilmore.
