1880 United States Federal Census

The image shows Sarah Bentley, 73, widowed, listed as mother-in-law in the Cyrus S. Clark household in the Village of Pulaski, Oswego County, NY, on 2 June 1880. This matches the claimed residence, place, date, marital status and relationship. Only the identification with the 1808–1886 individual depends on other evidence.
Matches: Line 14 reads "Bentley Sarah", white female, age 73, relationship "Mother-in-law" in the household of Cyrus S. Clark (family 30, dwelling 27); Age 73 gives a birth year of about 1807, which fits the claimed 1808 (born before 1 June 1880); The widowed column (11) appears to be marked on her line, which fits "Widowed"; Heading reads Village of Pulaski, County of Oswego, State of N.Y., enumerated 2 June 1880, ED 262, matching the citation; Her daughter Sarah S. is the wife of the head, Cyrus Clark, which explains "mother-in-law". Alida Bentley (38), listed as sister-in-law, is probably another daughter
Limits: The census gives an age, not a birth date, so it cannot confirm 1808 exactly; The citation says page 55d, but the sheet is stamped as page 4 of ED 262 (the 55d number is the Ancestry stamped page), which is a normal difference; The census does not show that she is the Sarah Bentley who lived 1808–1886; that identification rests on the claim's other sources; Her birthplace entries are ditto marks (N.Y.) and are hard to read
