Michael Ambrose McCormick was born about 1813 in Limerick (I think the city), Ireland. He married Johanna Lunden in her village of Bruff, Limerick. Children Michael 1835 Limerick, Thomas 1837, Elizabeth 1838, Ann abt 1839, Bridget Helena 1840 Bruff. I assume Thomas and Elizabeth died, as they were not on board when they then emigrated to New Zealand (Nelson) on the Bombay in 1842, during which a son was born and died. They left for Australia, can't find when, but I think it had something to do with the Maori uprisings. There is an Andrew born in NSW in 1843, haven't confirmed if same family, but same parents' names. I believe they had 2 daughters in Tasmania, 1848 and 1850. I am descended through Bridget Helena, who did indeed marry Michael Tobyn Keon in 1865.
