1940 United States Federal Census

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 2/4, tier record.
The readable 1940 census image shows Mary, wife, age 36, married, born Bohemia, in James Hejnal Sr.'s household in Milwaukee Ward 10. This matches the claimed residence, place, year, relation and marital status, and the age fits a 1903 birth. The surname is Hejnal, so the identification as Mary Konecny rests on Konecny being her maiden name, which the record cannot confirm. I rate it consistent rather than supporting.
Matches: Census is Milwaukee, Milwaukee, Wisconsin, ED 72-243, sheet 1B, taken April 1940, matching the citation detail; Lines 68-73 show household 20, James Hejnal Sr. (head, 51), with Mary as wife, age 36, marital status M, born Bohemia; Age 36 in April 1940 implies a birth year of about 1903-1904, which fits the claimed 1903; Relation (wife) and marital status (married) match the claim note; Children Frank, James Jr., Joseph and Rosemary are listed in the same household
Limits: The surname on the record is Hejnal (written Hejnal/Hajnal), not Konecny. Konecny would have to be Mary's maiden name, and the census does not give maiden names.; The citation does not name the line, so Mary Hejnal is identified only by fit (wife, age, Bohemian birth). It was not confirmed from the citation itself.; A census age gives a birth year, not a birth date, so it cannot confirm 1903 exactly.; The census does not show a link to the Konecny family or to the 1989 death.
