We have a Margaret Lacy (Lacey) married to one Patrick Hughs, both from Wicklow...married about 1836? Had daughter Susan baptized Roman Catholic..Oct 14, 1837 son Thomas, baptized 01 Jan, 1840...son Patrick, baptized15 April 1842...daughter Elizabeth, baptized 10 April, 1844. A Stephen Lacey was one of the children's sponsor...and they had a son they named Stephen, after they immigrated to Canada. Does this fit any of your family?
