1920 United States Federal Census

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 2/4, tier record.
Line 55 of the sheet shows Mary Konecny, daughter, female, white, age about 16, born in Bohemia, in the household of the head (Konecny, line 53, age 54). A birth in October 1903 would make her 16 in January 1920, so the age fits. The census cannot confirm the exact date or the village of Svatý Štěpán, so it is consistent but thin for this claim.
Matches: Census page shows a Konecny household in Manitowoc, Wisconsin (line 53-55), matching the citation's place and ED 103; Mary, daughter, age 16 (implies birth c. 1903/1904), fits a 1903 birth; Born in Bohemia per the census; parents also Bohemia, which is in the same region as Moravia (Czech lands); Immigration year appears to be 1905 (handwritten, partly legible), plausible for a child born in 1903
Limits: A census gives an age, not a birth date; 16 October 1903 cannot be confirmed; Place of birth is only 'Bohemia' (probably used loosely for Czech lands); Svatý Štěpán / Bylnice / Brumov and Moravia are not named; Handwriting is faint; the age and immigration year are hard to read with certainty; The record does not itself prove that this Mary is the person in the database, though the household fits; Age 16 on 12 January 1920 fits birth between January 1903 and January 1904, so 16 Oct 1903 is possible
