My ggrandfather Harrison CLEVENSTINE was born Oct. 16, 1821 in Derstown, now Lewisburg, Union Co., Pa. His parents were Christian and Mary WILLIAMS CLEVENSTINE. I believe there were at least two siblings, ELIZABETH and JACKSON CLEVENSTINE. Harrison left Pa. in 1854 and "roamd" between southern WI and northern IL before settleing in Stevenson, Co. IL in the late 1860's. Any information on Clevenstines or related WILLIAMS would be appreciated.
