1840 United States Federal Census

Validator (claude-sonnet-5-5, 2026-10-28): supports, confidence 3/4, tier record.
The readable original schedule lists Joel Seymour among the heads of household, with a male in the 60-70 column that fits his age in 1840. The margin and citation place the division in Stillwater, Saratoga County, New York. The household matches the claimed residence, but the record names no relationships, so it cannot prove this is the same Joel.
Matches: Image of the 1840 federal census schedule shows a head of household written as "Joel Seymour"; Left margin handwriting appears to read Stillwater, Saratoga County, matching the claimed place; Joel Seymour's household has one male aged 60-70, which fits a man born 1772 (age about 68 in 1840); The second image is the reverse of the same sheet and is marked page 221, matching the citation page, in the Northern District of New York
Limits: The census does not say which Joel Seymour this is. Identification with Joel⁶ Seymour (1772–1841) rests on name, age bracket and place.; Only an age range is given, so it cannot confirm the exact birth year.; The marginal place name is faint handwriting. The township reading rests partly on the citation detail.; The census shows residence as of the 1840 enumeration only, not exact dates.
