Ngairedith, re Mulvaney Marriages we think there's a glowing error.
John Joseph Mulvaney who was always called Jack and there's a lot written about this man was the oldest son but not the eldest child, that was Mary Ellen Mulvaney. He never married, in fact was a loner so that story in the NI newspaper details is rather interesting to say the least.
Jack died on 26/5/1971 and he and his sister, Elizabeth Catherine Kidd are buried next to each other in the Hokitika Cemetery. Their Plot and block references are 1678 in block 90 and Plot 1680 in block 90 respectively.
