Sharing some new information just acquired. John O'Connor in New York City - first knowledge of him in 1870. By 1895 he is owner of "O'CONNOR PRINTING COMPANY" which had locations all over Manhattan. Had at least two sons, John J. and Thomas. Wife might be Bridget Meahan/ Meehan. May have deceased around 1903 - 1904. He had a brother Michael, also in Manhattan. Anyone researching this group? Best wishes to all :)
