New York, U.S., Arriving Passenger and Crew Lists (including Castle Garden and Ellis Island), 1820-1957

Validator (claude-opus-5-5, 2026-10-28): consistent, confidence 2/4, tier record.
Line 22 of this 1903 Fürst Bismarck manifest lists Antonin Tauber, 17, Bohemian, last residence apparently Mostiště, bound for Chicago. On the following line Františka Tauber is joining her brother Václav Tauber in Chicago. Name, ethnicity and residence fit the claimed person, and the age implies birth about 1886, within a year of the claimed 1887. The record does not state the birth date or birthplace, so it is consistent with the birth claim rather than proof of it.
Matches: Line 22 of List 9 (S.S. Fürst Bismarck, sailed Hamburg 23 September 1903, arrived New York 2 October 1903) reads Antonin Tauber (written 'Tauber'/'Täuber'); Age 17, single, race or people given as 'Bohemian'; Last residence reads as 'Mostiště'/'Mostitz', consistent with Mostiště in Bohemia; Final destination Chicago, Ill.; the next line, Františka Tauber, 20, is going to brother Václav Tauber, 4717 Hermitage Ave, Chicago, which fits a Tauber sibling group from the same place
Limits: A passenger list gives an age, not a birth date or birthplace. Age 17 in autumn 1903 implies birth about 1886 (roughly October 1885 to September 1886), while the claimed 6 August 1887 would make him 16. That is within the one-year tolerance, but slightly earlier than the claim; The manifest gives last residence, not place of birth; The district (Rokycany) is not stated, and the residence entry is hard to read in this handwriting
