1910 United States Federal Census

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 2/4, tier record.
The 1910 census image shows Tony Tauber, 23, born in Bohemia to Bohemian parents, living in Collinsville Ward 3 with wife Lizzie and son William. This fits an Antonín born in Bohemia in 1887, with the age one year high for an August birth. It does not state the birth date or village, so it can only be consistent with the claim.
Matches: Line 14 shows 'Tauber, Tony' (Tourny), head of household, which fits Antonín as a Tony/Anthony variant; Born in Bohemia, with father and mother also born in Bohemia, which fits a birth in Mostiště, Rokycany, Bohemia; Age 23 on 27 April 1910 implies a birth around 1886–87, close to the claimed 6 August 1887 (he would be 22 if born then); The immigration year looks like 1887, which would fit an emigrant family with an infant son (hard to read); Collinsville, Madison, Illinois is a plausible residence for a Czech coal miner's family
Flags: The age of 23 implies birth about 1886–87. A birth on 6 Aug 1887 would make him 22 in April 1910, so this is a one-year difference at the edge of tolerance.; The citation says page 24a, but the image sheet number reads 23A. This is a minor mismatch in the citation detail.
Limits: A census gives an age, not a birth date, so it cannot confirm 6 August 1887; It gives only 'Bohemia' as the birthplace, not Mostiště or Rokycany; The record does not link this Tony Tauber to the Antonín (1887–1939) in the database; that would need spouse, children or other records; The handwriting is hard to read, including the immigration year and the enumeration district number
