1910 United States Federal Census

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 2/4, tier record.
The image shows the George S. Wood household (sheet 4A, ED 436, Chicago Ward 7), with a son on line 5 who appears to be "George S., Jr.", age 16, born New Jersey. This fits the name "George S. Wood Jr." for the claim. The age of 16 does not fit a 1891 birth (it would be 18 or 19), so the birth year should be checked, but the name itself is consistent.
Matches: Household of George S. Wood (head, age 51, b. Canada-English) in Chicago Ward 7, Cook, Illinois, ED 436, sheet 4A, matches the citation place and page; Son listed as "George S., Jr." (apparently), age 16, single, born New Jersey, father b. Canada-English, mother b. New York; Age 16 in April 1910 implies birth about 1893–94, close to the claimed 1891; Wife Mary B. and siblings Norman B., Franklin and Emilie W. are in the same household
Flags: Age 16 implies birth c. 1893-94, which is about 2-3 years later than the claimed 1891; this is a discrepancy to check, though the age may be misread or misreported
Limits: A census gives name and approximate age, not a full middle name, so "Slack" is not shown, only the initial S.; The census cannot confirm the death year of 1977; The handwriting of the son's name is hard to read at this resolution; "Jr." is inferred; The census does not prove this is the person born in 1891 without other evidence
