Hello. I am trying to trace my grandmothers family, here is what I have. Dennis Patrick or Patrick Dennis O'Connor born around 1817 in Ireland. Honora O'Connor ( Madigan ) born around 1820 in Ireland. Children. Thomas, born around 1840 in Ireland. Timothy, born around 1842 in Ireland Mary Ann, born around 1844 in Ireland Bridget L, born around 1849 in Ireland. ( My great grandmother ) The O'connor family left Ireland around 1850/51 and came to Boston, Ma. May have came by way of Canada, not sure. Any information on this family will be appreciated. Best wishes. Bob.
