1930 United States Federal Census

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 2/4, tier record.
Line 6 on sheet 30A (Manitowoc, Wisconsin) lists Peter Konecny, 36, born Czechoslovakia, immigrated 1913, welder in a shipyard. This agrees with a birth in 1893 in the Czech lands, but the census cannot confirm the exact day or the Svatý Štěpán birthplace. It is consistent but thin evidence for the birth claim.
Matches: Line 6 shows Peter Konecny, head, age 36, born Czechoslovakia (both parents also Czechoslovakia), which implies a birth year of about 1893/1894; Surname Konecny is a variant of Konečný and Peter of Petr; Immigration year 1913 and Bohemian mother tongue fit a Moravian/Czech emigrant; Wife Annie (37) and children Joseph, Mary, Frank, William in household; census taken April 1930, so age 36 gives a birth between April 1893 and April 1894, which fits 28 June 1893 only loosely
Flags: Age 36 on 26 April 1930 implies birth between 27 April 1893 and 26 April 1894, whereas a 28 June 1893 birth would make him 36 (June 1893 to April 1930 is 36 years 10 months), so it is compatible. Slight tension only if the enumerator counted differently.
Limits: Census gives only age and country (Czechoslovakia), not a birth date or the village of Svatý Štěpán/Bylnice; Does not name the middle name Pavel or confirm the parish Brumov; Does not prove that this Peter is the same person as the one in the database; that needs a link such as a spouse or children's names from other records; Death date of 1936 cannot be checked here
