Hi Lyn, I have just found a brother Patrick Joseph Tierney to my Margaret Tierney who was born about 1840. He was a long time resident of Rockhampton, Queensland when he died on 23 June 1902. He was married to Ellen Page and had a number of children. I do not know of any connecion between Catherine and Patrick Joseph but he had the same parents as my Margaret which were Patrick Tierney (blacksmith)and Mary Slavin. Do you have any information on P J T or any other info on Catherin's parents?
