New York, U.S., State Census, 1875

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 3/4, tier record.
The 1875 NY State census image shows Sarah Bentley, about 67, born in Saratoga, living in the Cyrus Clark household in Richland, Oswego County. An age of 67 in June 1875 implies a birth year of about 1808, and Saratoga County fits Stillwater. The record does not give the exact day or the town, so it is consistent with the claim but does not fully state it.
Matches: Right-hand page (Richland, Oswego Co., 1875) has a 'Sarah Bentley' on about line 39 in the household of Cyrus Clark (dwelling 185); Her age reads about 67, which implies a birth around 1808 and fits the claimed 1808 date; County of birth reads 'Saratoga', which is consistent with Stillwater, Saratoga County; A younger 'Ann E Bentley' (about 33) is listed in the same household, which fits a family group
Limits: A census gives an age, not a birth date, so 2 September 1808 is not confirmed; The census gives only the county of birth (Saratoga), not the town of Stillwater; The handwriting is small and faint at this resolution, so the age and birthplace readings are somewhat uncertain; The record does not show that this Sarah Bentley is the one who died in 1886; that rests on other evidence
