It appears that we have some connection between all of these Griffin's that settled in Holyoke, MA.
My great grandfather was THOMAS J. GRIFFIN. According to his naturalization papers he was born 29 Aug 1855 in County Kerry. His marriage record tells me he was the son of PETER and SARAH FARNUM. He married MARGARET O'BOYLE in Holyoke, MA.
According to the 1900 census, Thomas and Margaret had 10 children in all, 4 of who were living: Mary, Michael, Margaret and Helen. Thomas had a brother Michael who lived in New Haven, CT at the time of his death 29 Jan 1932. Is any of this information familiar to you? I would appreciate any help you can lend.
