New York, U.S., State Census, 1855

Validator (claude-sonnet-5-5, 2026-10-28): supports, confidence 4/4, tier record.
The image of the 1855 NY state census for Sandy Creek, Oswego County shows Sarah S. Bentley, age 46, female, as "Wife" in the Bentley household (dwelling 379, family 446). Place, year, relationship and age all match the residence claim. The only gap is that the age gives an approximate birth year and the head's first name is hard to read.
Matches: Header reads Sandy Creek, County of Oswego, taken June 1855, which fits the claimed place and date; Dwelling 379, family 446 lists Elias(?) Bentley, 49, M, born Saratoga, followed by Sarah S. Bentley, 46, F; Sarah S. Bentley's relation to head is written as "Wife", matching the claim; Age 46 implies a birth year of about 1808–1809, matching the 1808 birth year; Children Helen, Wm H., Saml D., Frances M., Ann E., Sarah, Esther and John I. Bentley follow in the household
Limits: The head's first name is hard to read (looks like Elias or Elihu), so the husband's identity is not confirmed here; The census gives age and residence only, so it cannot confirm her full birth date or death year; Whether this Sarah S. Bentley is the same Sarah Bentley (1808–1886) in the database rests on name and age alone
