I'm trying to find a James LUSK, born 1791 in Ireland, who appears on the 1850 Westmoreland County, PA census in Derry Township. His wife is listed as Elisabeth, born about 1786 in Ireland. The children listed with them are James, born 1828 in PA and Margaret born 1830 in PA. Their daugther Hannah married Israel McQuiston of Westmoreland County. Hannah was born about 1824 in PA and died in August of 1905 in Wichita, Kansas. Both her husband, Israel and her brother James (b. 1828) were shown on the 1850 census as working as "Boatmen". I have the McQuiston line traced back, but I would love to know more about James and Elisabeth Lusk.
