1800 United States Federal Census

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 3/4, tier record.
The image of the 1800 Stillwater, Saratoga, New York census page has an entry "Joel Seymour" with a household of 1 male under 10, 2 males 16-26, 1 male 26-45, and females including 3 under 10, 3 aged 10-16 and 1 aged 26-45. The name matches the claim and the age bracket fits a man born in 1772. The record does not independently identify him as the Joel Seymour of 1772–1841.
Matches: Image shows an entry reading "Joel Seymour" as head of household on the Stillwater page; Census place matches the citation (Stillwater, Saratoga, New York, 1800); Household shows one free white male aged 26-45, which fits a man born 1772 (age about 28)
Limits: A census lists the head of household's name only; it does not give a birth or death date, so it cannot confirm the dates 1772–1841; The claim concerns the person's name only, and the census cannot show that this Joel Seymour is the Joel⁶ in the database rather than another man of the same name; The generational number (⁶) and any parentage are not shown in the record; Handwriting is faint, but "Joel Seymour" is reasonably legible
