1940 United States Federal Census

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 2/4, tier record.
The image is a readable original 1940 census sheet. The only plausible match is Mary, 36, wife of James Hejnal Sr., born Bohemia. Her age fits an October 1903 birth and her foreign birthplace is plausible for Moravia. The record does not state the birth date, the exact place or her maiden name, so it can only be consistent if she is already known to have married Hejnal.
Matches: Household 20 (line 68–73), N. Reservoir Ave, Milwaukee: James Hejnal Sr., head, 51, born Bohemia, with wife Mary, 36, born Bohemia; Age 36 on 1 April 1940 gives a birth year of 1903 or 1904, which fits 16 October 1903 (she would have been 36); Foreign birth in the Czech lands (listed as Bohemia) fits a birth in Moravia, then part of Austria-Hungary; She is the only woman on the sheet named Mary with a Czech birthplace and a fitting age
Limits: The census does not give the maiden name Konecny, so it cannot show that this Mary Hejnal is Mary Konecny; that depends on a separate marriage record; It gives only an age, not a birth date, so 16 October 1903 is not confirmed; It gives the country 'Bohemia', not Svatý Štěpán, Bylnice or Brumov, so the Moravian place of birth is not confirmed. Enumerators often wrote 'Bohemia' for all of the Czech lands; The surname is spelled Hejnal here (the handwriting is hard to read), so identification relies on the family context in the database
