My g.g.grandfather Samuel Mawhinney married a Jane Brennan in Eglinton Street Church, Belfast in 1866. Samuel Mawhinney's father was a John Mawhinney (deceased) at the time of marriage. Jane Brennan's father was a James Brennan. Witnesses at the marriage were a William Wilson and a Barbara Brennan. Does anyone have any connections with these families. Isobel
