1920 United States Federal Census

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 3/4, tier record.
The image shows the 1920 census, Manitowoc, sheet 7B, with the Konecny household at lines 53–55. Line 55 is a daughter, Mary, age 16, born Bohemia, which fits a 1903 birth and the name Mary Konecny. The record supports the name and is silent on her death date.
Matches: Household of Konecny (head, age 54, born Bohemia) in Manitowoc, Wisconsin, sheet 7B, ED 103, matches the citation detail; A daughter named Mary (Marie), age 16, born Bohemia, is listed in the household, which implies a birth year of about 1903–1904; Surname Konecny matches the claim; the given name Mary matches the claim
Limits: The claim is only about the name, and the census supports only the name as enumerated, not the 1903–1989 dates; The age of 16 on 12 January 1920 implies a birth year of 1903 or 1904, so it fits but does not confirm 1903; The head's given name and the exact spelling of the daughter's name are handwritten and hard to read at this resolution; The census cannot show her death year (1989); The census does not independently establish that this Mary is the same person as the database individual, though the age and surname fit
