1950 United States Federal Census

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 1/4, tier record.
The image shows Joseph Konecny, 50, welder, born Bohemia, in Milwaukee, in a household with wife Agnes and three sons. The record is consistent with a Czech-born man but cannot confirm a birth date of 17 Feb 1901 or the specific village. The age implies 1899–1900, which is a mild discrepancy with 1901, and 'Bohemia' rather than Moravia is another soft mismatch. Weak support at best.
Matches: Joseph Konecny, head of household, line 108, age 50, born Bohemia (implies birth about 1899–1900); Wife Agnes, 46, born Bohemia; sons Robert, Walter, Joseph; Both parents' birthplace listed as Bohemia (sample line 21), consistent with Czech origin; Naturalized ("Yes" in the column for foreign-born persons), consistent with an immigrant
Flags: Age 50 on the April 1950 census implies birth in 1899 or 1900, not 1901 (a 1–2 year gap, with 1901 requiring age 48–49)
Limits: A census gives an age and a country of birth, not a date or a specific place; Does not name Svatý Štěpán, Bylnice, Brumov or Moravia; 'Bohemia' is a general country answer and Moravia would be a different region; Census ages are often imprecise, especially for immigrants; Identity as the same Joseph Konecny rests on name and Bohemian birth only; the record names no parents or places to tie him to the claimed individual
