Dear Piers, I agree, it seems very unlikely that the timbers for the Industry were exported from Ireland to Canada for its construction. Unless that Canadians were sourcing Oak in Ireland at the right price. Its beyond me, but stranger things have happened. The US for instance, are probably one of the biggest oil importers in the world, even though they have significant reserves of their own. I thought the Industry ON 25450 was registered in Dublin when it sailed for Australia in December 1857 and that the agents ( I assume the owners) were T.H. Martin, Forrest and Co. Then soon after she arrived in Melbourne she was sold, in the January of 1859, and reregistered out of Melbourne to her new owner John Jones. Thanks to Jenny I now have a seamans ticket number for John Mallin , its ticket No. 337790. According to the ticket, John Mallin was born 8th November 1826 in Dublin; he received his seamans ticket when he was almost 20; he went to sea as a carpenter; he had no service in the Royal Navy or Foreign services. His ticket was issued in Liverpool on the 6th of August 1846 when he first went to sea His voyages record up to 1854 indicates that he out to sea in 1846 on 1657.62.57 ----69. 21. 8 ( this could be 62.21.8) and home in 1847 on 1657.62.57 - 27.4.3. I'm not sure what the numbers mean. There are initials above the numbers but I cant make them out , it could be JM. He was married in 1848 in Dublin. All the best and thank you very much for your help. Sean
