Wild guess here, so...My great grandfather was Robert Patrick Guinan(born around 1861 in Ireland, possibly Limerick), he had a brother Edward and a sister Bridget...they came to the US around 1880 (QueensTown to Liverpool to New York)..."Pat" moved to California, not sure where Edward went, and Bridget went to New York area after brief stay in California.
I have no info as to who his parents are etc. We might even be related...Bridget (if this is the same woman) was my grandmother (Marguerite Mary Guinan DeVoe)'s aunt.
Love to hear from you...Pamela DeVoe Ash
