I know it has been some time since you posted your query. I was born Lutton and am descended from John Lutton who emigrated to Australia in 1842 in company of his uncle William (guardian?)and other family, from Newry, County Down, N. Ireland. I have some family history re being descended from from William Lutton b.1709 and Ralph Lutton b.1723, but can't put it all together from the Irish side. Have you been able to find out more? Kindest regards, Priscilla.
