Might be William Frable, age 13, Lackawanna Co., in the 1880 census. A search at www.familysearch.org shows this as the closest est. year of birth for "William Frable" in PA. (If age 23 in 1890 was correct.) This Williams was in the household of Adam Frable in 1880. Do other folks in Adam's household fit into your tree? J.R. Maxwell Delaware Co.,OH
