I am looking for info on my wife's great-grandfather David O'Connor (listed as David J. in one NY Census) born Mar 1858 in Knocknagree County Cork Ireland. Was in South Glens Falls, NY by 1880 and married Bridget Nolan of County Wexford in 1886. Died South Glens Falls, NY 1932. Any info on ancestors or parents or siblings would be greatly appreciated.
