That is not the same person, that Benjamin Sweet was one of three residing in Huron County Ohio in 1850, mine was married to Anne Barber in 1850 (married 1839) he moved on to Hancock County Illinois by 1860 and died 24 Dec 1893 and buried in Leavenworth National Cemetery, reported to be 85 years old. I believe my Benjamin was in Pickaway County Ohio in 1840 as his oldest son gave his place of birth on Civil War Enlistment Register as Circleville, Ohio 1837, There was a Benjamin Sweet in Pickaway County in 1840 US Census.
