GenNut on Family Tree Circles

I am seeking information on the family of my g-grandmother Margaret O'Halloran (1889-1969) and her sister Mary. They lived in New York City, possibly Brooklyn or the Bronx. Their parents were born in Ireland and came to New york around 1875 I think but am not certain of the exact dates. Mary O'Halloran wed Thomas Patrick Reardon (1883-1966) but died after bearing him two children. Thomas travelled for a few years then returned to NYC and wed Mary's sister Margaret O'Halloran - fresh from a convent in NYC. Family lore says Mary also was in the convent before her marriage. I have the desendants of Margaret O'Halloran and Thomas Reardon on my homepage.
