1930 United States Federal Census

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 2/4, tier record.
On lines 46-47 of the sheet, James Taubr (age 54, born Bohemia, carpenter for the railroad, immigrated 1901) is shown with wife Frances. The Anglicized first name, the age and the Bohemian birth fit Václav Tauber b. 1876. The record supports a name variant only by inference, so it is consistent rather than conclusive.
Matches: Household at dwelling 391, family 691 lists "Tauber/Taubr, James" as head, age 54 (born about 1876), born Bohemia, father and mother born Bohemia; Immigrated 1901, language Bohemian; the age fits a man born in 1876; Wife Frances, 54, also born in Bohemia; Chicago, Cook County, Illinois matches the citation detail; sheet 36A, ED 16-499 match the citation
Flags: The census names him "James", not Václav; this is an Anglicized form, and the match rests on age and birthplace; The age of 54 implies birth around 1875-76, so it is consistent with 1876 but does not confirm it
Limits: The census gives no birth date, so it cannot confirm 1876 exactly; The census does not mention Václav and gives no death information (1956); The record contains no evidence linking James to the name Václav beyond the usual anglicization; The surname is hard to read (Taubr/Tauber)
