Please let me know if you have information on any of their relatives. My third great grandmother was Sarah Ann Flynn from New Market, County Cork, Ireland, per her headstone. She married Michael P. Regan/Reagan also from somewhere in Cork. I cannot find birth marriage or death records for her.
If you find a Sarah or Sarah Ann Flynn who came to the US, NYC or RI, please do let me know. :) Her dates are 1833-1876, according to her headstone.
