Hi all I am looking for any information on Michael O'BRIEN who married Ann DUKE at St. Mary's Cathedral Sydney 13 November 1854. Ann DUKE immigrated to Australia 12 Jan 1850 as a teenager and was an orphan and according to shipping records her parents were John and Mary. They had one child, my g grandmother Mary Ann Josephine O'BRIEN and probably more but with names like Michael and Ann O'Brien they are hard to trace. Any information would be greatly appreciated. I have lots of SMITHS in the family and find they are a breeze!! Regards Judy Brooks
