1920 United States Federal Census

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 2/4, tier record.
The page has no Mary W Bentley, but Mary Wood (59, born New York) heads a household that includes William and Caroline Bentley as brother- and sister-in-law, so she may be William's sister under her married name. Her age and birth state fit the claimed 1861 New York birth. The census cannot confirm the exact date, the Brooklyn place, or that this Mary is the person in the claim.
Matches: The 1920 census, Chicago Ward 3, ED 149, sheet 3B, lists Mary Wood, wife of George S. Wood (head), age 59, born New York.; The same household includes William Bentley (brother-in-law, 50, born New York) and Caroline Bentley (sister-in-law, 42). Mary Wood may therefore be a Bentley by birth, which would explain the Bentley link.; An age of 59 in January 1920 implies a birth around 1860–61, and a birth state of New York fits Brooklyn.
Limits: The woman is recorded as Mary Wood with no middle initial. The record never names her as Mary W Bentley, so the link depends on the Bentley in-laws and on this being her married name.; Birthplace is given only as the state, New York, so Brooklyn, Kings County is not confirmed.; A census gives an age, not a birth date, so 20 April 1861 is not confirmed. A person born that day would be 58 on 7 January 1920, one year younger than the 59 recorded, which is within tolerance.; The age and relationship entries are in a handwritten, partly faint image and are hard to read with certainty.; The record says nothing on her 1938 death.
