1870 United States Federal Census

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 2/4, tier record.
The image is readable and shows Sarah Bentley, age 64, born New York, retired, in Richland, Oswego County, on 24 June 1870. The state of birth fits the claim, but the age implies about 1805-06, not 1808, and the record gives no day, month or town. It is thin support and cannot confirm the birth date or place, and the age gap needs checking against other sources.
Matches: Line 23 reads "Bentley Sarah, 64, F, W, Retired, born New York" in the Town of Richland, Oswego County, NY, 1870, matching the citation's census place; Age 64 in June 1870 implies a birth year of about 1805–1806, close to 1808 (a difference of 2-3 years); Birthplace New York is consistent with Stillwater, Saratoga County, NY
Flags: Age 64 implies a birth around 1805/1806, about 2-3 years before the claimed 1808. This is more than the 1-year tolerance, though census ages are often imprecise; Nothing in the record ties this Sarah Bentley to the Stillwater-born person. She lives in Richland with Ann Eliza Bentley (27) in the household of Malcom Hollis, and no relationships are given
Limits: A census gives an age and a state of birth, not a birth date or town; The 1870 census does not state relationships, so identity rests on name, age and location; The claimed birth date of 2 September 1808 and the place Stillwater cannot be confirmed from this record; The page number in the image (28) differs from the citation's 407B, which is probably the Ancestry image number rather than the printed page
