1833 Birth:2511 Birth year of 1833 estimated based on age (17 years) in 1850 census enumeration; birth place of Ohio taken from same enumeration. Age of 21 years on tombstone may be a transcription error or an illegible stone. If Sarah were actually 21 at the time of her death in 1857, she would have been 14 (and married) at the time of the 1850 enumeration, which does not seem reasonable.

1850 U.S. Census:2511 Sarah enumerated in the household of Mary Wood in Burlington Township, Licking County, Ohio with her husband Almon Wheeler as a female, age 17, born in Ohio.

1857 Tombstone:171 Buckland Cemetery, Logan Township, Auglaize County, Ohio.
