I am looking for information on Margaret Tierny, b 11 Aug 1825 in Ireland, who married Daniel Healy, b 1822 (Ireland) in 1846 (Ireland). I don't know where in Ireland they were from, but it is possible Margaret is from County Mayo, possibly Westport. I am trying to determine if she is a sister of my g-grandfather, Thomas Tierney, b 1819 in Westport, Co Mayo. Thanks!
