1920 United States Federal Census

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 2/4, tier record.
The 1920 Manitowoc census lists Peter Konecny, a 28-year-old Bohemian-born head of household, with an immigration year that appears to read 1913 and a 'Pa' (first papers) entry. That fits an arrival in 1913 and a declaration of intention filed before 1921. The record cannot confirm the exact date, port or ship, which have to come from the ship manifest or the naturalization papers. The stated age is slightly younger than a 1893 birth would give.
Matches: Line 57, dwelling 132, family 145: Konecny, Peter, head, born Bohemia, male, white, age 28, married, in Manitowoc city, Wisconsin; Year of immigration appears to read 1913, matching the claimed 1913 arrival; Naturalization column appears to read 'Pa' (first papers filed), consistent with a 1915 Declaration of Intention before a 1921 petition; Wife Anna, 28, born Bohemia, is listed in the same household, and he is a Bohemian immigrant
Flags: Age 28 on 12 Jan 1920 implies birth around 1891–92, which is 1–2 years before the claimed 1893 birth year. This is a mild discrepancy, and census ages are often inexact.
Limits: A census gives only the year of immigration, not the day 20 August 1913; It does not show the port (New York) or the ship (Kaiser Wilhelm II); The handwriting is faint, so the immigration year and the 'Pa' entry are only moderately legible; Identification as the same Petr Pavel Konečný rests on name, origin and approximate age only; no parents or other identifiers are given
