1930 United States Federal Census

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 3/4, tier record.
On sheet 4B, line 77 lists Mary as wife of James Hejnarl/Heynarl, age 27, born Bohemia-Austria, with immigration year 1914 and status 'al'. That fits a Mary born about 1903 who arrived in 1914. The record does not name her as Konecny, so the identification rests on the database's existing link between her and this household.
Matches: Line 77 shows Mary, wife of James (surname appears as Hejnarl/Heynarl), age 27, which implies a birth around 1902–1903 and matches 1903.; Her birthplace is given as Bohemia-Austria, and both parents are also from Bohemia-Austria, which fits a Czech-born woman with a Konečný maiden name.; The year of immigration column reads 1914, with naturalization status 'al' (alien), which matches the claimed arrival year.; The household is in Milwaukee, Wisconsin.
Limits: The census gives only a year of immigration, not a date, ship or port.; The surname on the sheet is not Konecny. The link to Mary Konecny depends on Konecny being her maiden name, and the census does not give maiden names.; The handwriting is hard to read, so the surname and the 1914 entry are read with some uncertainty.; The census cannot show her death in 1989.
