1910 United States Federal Census

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 2/4, tier record.
The page lists Mary B Word, 48, wife of George S. Word, in a household with Emilie M. Bentley, mother-in-law. That fits Mary being a Bentley by birth and born about 1861–62. The record does not state her maiden name, and her initial reads B where the claim has W, so it is consistent but not confirming of the full name.
Matches: Household 62 in Chicago Ward 7, ED 436, sheet 4A includes Mary B Word, wife of George S. Word, age 48 (born about 1861–62), which fits a woman born 1861; Emilie M. Bentley, age 76, widowed, is listed as mother-in-law in the same household, which supports a maiden name of Bentley for the wife; Mary B's birthplace is New York and her mother's birthplace appears to be Pennsylvania, matching Emilie Bentley's Pennsylvania birth; The couple's daughter is Emilie W., which fits a family link to Emilie Bentley
Flags: The record gives the wife's name as Mary B Word, not Mary W Bentley. The middle initial reads B, not W.; The surname Bentley appears only on the mother-in-law. It is not given for Mary herself.
Limits: A census does not give a maiden name, so Bentley is only inferred from the mother-in-law's entry; Age 48 gives a birth year of about 1861–62, not an exact date; The record says nothing about her death in 1938; The handwriting of the middle initial and of the parents' birthplaces is hard to read; The record does not confirm that this Mary is the same person as the database's Mary W Bentley
