I am looking for John Potaskie/Postaky and his family. He was a convict transported on the Calcutta. He was born 1774 in England died in Hobart 1824. Richard Kelcey was a convict but I dont know what ship he arrived on. He was born 1789, England. Also on the Locke family, Emily, Mary & Martha arrived on the Arab I believe 1842. I found it listed as a convict ship, not sure if there were or not. Hope someone can help.
