1930 United States Federal Census

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 2/4, tier record.
The 1930 census, Manitowoc Ward 6, sheet 30A, line 6, shows Peter Konecny, age 36, born in Czechoslovakia, with immigration year 1913 and naturalized status. This agrees with the claimed 1913 arrival but does not give the exact date, port or ship. It is consistent only; the specifics must come from the naturalization papers.
Matches: Line 6: Peter Konecny, head, age 36 (born about 1893), born Czechoslovakia, Bohemian mother tongue; Year of immigration to the US given as 1913, matching the claimed 1913 arrival; Naturalization status "Na" (naturalized), consistent with a 1921 petition for naturalization; Residence is Manitowoc, Wisconsin, a Czech-American community
Limits: A census gives only a year of immigration, not the day (20 August 1913), the port (New York) or the ship (Kaiser Wilhelm II); The record does not name the ship or cite the declaration or petition; The household is listed as Peter, not Petr Pavel, with no middle name; The handwriting in column 22 is slightly hard to read, though it appears to be 1913; Date, place and ship rest on other sources (the Declaration of Intention and the Petition for Naturalization)
