Mary was married to Martin MacEvoy at a time and place unknown. Other children of this union are:
Elizabeth MacEvoy, baptised 14th January 1830, and
Anne MacEvoy, baptized 29 March 1832.
All three girls were baptised in the Roman Catholic church in the District of Johnstown, Kilkenny, Ireland. Sponsors of the girls and presumably family, friends or neighbours of Mary and Martin include:
Edmund Burk, Ellen Shortall, Martin Neal, Mary MacEvoy and Elizabeth (Betty) Kavanagh.
I was unable to locate any further children for Mary and Martin after Margaret's birth in 1833. I suspect that Mary has died at some unknown time prior to 1840 when Martin MacEvoy married for a second time.
