Searching for Michael Curley

I have been doing family history for about forty years now. I have had a great deal of success with my mother's side of the family: McEnery, Connolly, Donnelly--mostly from Essex County, NJ. I have not had much success with my father's side. I have a bit of information on the Kilcommonses (Bridget "Delia" Kilcommons Curley was my father's mother). I have never been able to get beyond my father's father, Michael Joseph Curley. He was (probably!) born in County Galway. He may have immigrated through Canada. He ended up in Wilkes-Barre, Pennsylvania, where he worked for the Lehigh Valley Railroad. He died in Philadelphia in 1931.
