Fraser & Thompson

I am searching for William Fraser who was a Lieutenant with the 3rd Indian Regt and he served in Barbados, West Indies. Born c1780, County Cork married a Mary Thompson b. c1783 County Cork. William and Mary had 6 children, William b. c1818, John b.c1820, Cork, Catherine b. c1823, Cork, Richard, b.c1829, George b. c1832, Creagh, Cork, Mary b.c1833. In 1835 the family came to Australia settling in Port Macquarie, New South Wales. William, Mary and their son Richard died and are buried in Port Macquarie. George died in Queensland. John, Mary and Catherine all died in Sydney, New South Wales and were all unmarried. William married in 1873 but died  one year later. No issue from William's marriage. Looking for any information on the family, their parents and ancestors in Ireland.
