1920 United States Federal Census

Validator (claude-sonnet-5-5, 2026-10-28): supports, confidence 3/4, tier record.
The 1920 census image, sheet 6A, line 50 lists Frank Konecny, head, age 24, born in Bohemia, with immigration year 1912 and "PA" in the naturalization column. This matches the claimed 1912 arrival and a birth around 1895. The only gaps are the handwriting legibility and that the census gives only a year, not a full arrival record.
Matches: Line 50 shows "Konecny, Frank", head, age 24, married, which fits a birth year of about 1895 for František (Frank); Year of immigration in column 13 appears to read 1912, matching the claimed arrival date; Naturalization column shows "PA" (first papers filed); Born in Bohemia, with Bohemian-born parents and Bohemian mother tongue, which fits a Czech immigrant; Census place Manitowoc, Wisconsin, ED 110, sheet 6A agrees with the citation detail
Limits: Surname on line 50 is handwritten and partly cut off, so it is read as Konecny/Konecny-like with some uncertainty; The census gives a year of immigration, not an arrival date, port or ship; Frank is assumed to be František; the census does not confirm the full name or the 1895 birth year beyond age 24; The immigration year digits are small and not perfectly clear
