1840 United States Federal Census

Validator (claude-sonnet-5-5, 2026-10-28): supports, confidence 3/4, tier record.
The page headed Sandy Creek lists 'Eliza/Elias Bently' with one man aged 30–40 and a young family, and the second sheet carries page number 287 and 'New York'. That supports an 1840 residence in Sandy Creek for Elias Bentley. The first name is hard to read, and the age bracket is broad, so confidence stops at 3.
Matches: Page 1 of the schedule has 'Sandy Creek' written in the top-left heading, and the second sheet reads 'State of New York' and is numbered 287, matching the cited page; A household headed by 'Eliza/Elias Bently' is listed on the page, a spelling variant of Bentley; The head is a male aged 30–40 (one tick in the 30–40 male column), which fits a man born in 1806 (age about 34); The household has young children (males under 5 and 5–10; females under 5 and 5–10) and a female aged 30–40, consistent with a family man of that age
Limits: The image is dark and the head's first name is handwritten as 'Eliza' or 'Elias'. It is probably Elias, but it is not certain.; A census age bracket (30–40) does not confirm the 1806 birth year.; The county, Oswego, is not legible on the image. It is taken from the citation, and Sandy Creek is in Oswego County.; The 1840 census names only the head of household, so it cannot confirm family relationships.
