My great grandfather was Robert Patrick Guinan...born 1861 in Ireland, we believe in Limerick. We also believe that he emigrated to the U.S. around 1880. I know (per US Census in 1910) he listed that his parents too were born in Ireland. He married Hanorah Louise McAuliffe in 1888.
Have you any hints, suggestions as to where I may find more information about them?
Thank you,
Pamela Ash
