Hello again, We had a minor breakthrough on "our" Mary O'Neill; we now know the following: Mary O'NEILL, born in NYC about 1845, daughter of Jerry O'NEILL and Mary SHEA. Mary O'NEILL married James SULLIVAN about 1864; she died in NYC in December of 1936. Does any of this match up to anything any of you have? As always, full of hope that I'll "find" our O'Neills, Holly Sullivan
