Like you I've been trying to find proof that Jacob is the father of George Beckley. I have copies of the wills of both Jacob & Mary Beckley and have looked at census reports forVA for 1820 that lists a George Beckley in Washington County VA. The 1830 Census for Stark Cty OH lists George Beckley as head of household with 2 adults aged 60-70 living with him. The 1840 census for Coshocton Cty OH lists George along with William Watson age 84 living in the same household. The 1850 Census lists George along with wife Nancy & children Samuel, Jacob, Lemual, Josiah, Sarah, Henry, Louisa & Tabitha.I also have a listing from St Johns Cemetery in Mt Vernon OH for George Beckley d 2 Jul 1883 age 78y, 6m, 7d & Nancy A. Beckley d 4 Aug 1895 age 91y, 7m, 10d.
