1940 United States Federal Census

Validator (claude-sonnet-5-5, 2026-10-28): supports, confidence 3/4, tier record.
On the page, household 20 (line 68 onward) is James Hejnal Sr., 51, with wife Mary, 36, both born Bohemia. Column 17 says 'Same House' for April 1, 1935, so the family lived in Milwaukee then. Mary's age fits a 1903 birth. Whether this is the Mary Konecny in the database depends on the husband and maiden name, which this record does not confirm.
Matches: Line 69 is Mary, wife of James Hejnal Sr. (line 68), aged 36, born Bohemia. That implies a birth year of about 1903–04, which fits Mary (1903–1989).; Column 17 (residence April 1, 1935) reads 'Same House' for the household. The 1940 address is in the City of Milwaukee, Milwaukee County, Wisconsin, so she lived in Milwaukee in 1935.; The image is a readable original 1940 census page. Sheet 1B, ED 72-243 and Milwaukee 10th ward match the citation detail.
Limits: The census shows her as Mary Hejnal, a married name. It does not give her maiden name Konecny, so the link to Mary Konecny rests on the database's own identification of her husband.; The 1935 residence is given only as 'Same House', so the exact 1935 address is not recorded; it is inferred from the 1940 address.; The 1935 residence is the answer to a retrospective census question, not a record made in 1935.
