Staatsarchiv Hamburg, Hamburg Passenger Lists, 1850-1934

Validator (claude-opus-5-5, 2026-10-28): consistent, confidence 2/4, tier record.
On the right-hand page of Hamburg list Band 147, p. 2439, 'Tauber, Anton' is followed by 'Franzisca', aged about 20, residence apparently 'Mostitz', nationality Austrian. Mostitz is plausibly the German form of Mostiště, and an age of 20 fits an 1883 birth if the voyage was around 1903. However, the record states only an age and a residence, not a birth date or birthplace. It is therefore consistent with the birth claim but does not establish it.
Matches: Right-hand page, lower entries: surname 'Tauber' with 'Anton' and, on the next line, 'Franzisca' (a German form of Františka); Franzisca's age reads about 20, which implies a birth around 1882–1884 if the list is from about 1903, consistent with 1883; Previous residence (Bisheriger Wohnort) for the Tauber entries appears to read 'Mostitz', plausibly Mostiště, Rokycany district; Nationality (Staatsangehörigkeit) given as 'Oest' (Austria), consistent with Bohemia under Austria-Hungary; Family-status column next to the Tauber entries appears to say 'Schwester' (sister), suggesting Franzisca travels with a sibling Anton
Limits: A passenger list gives an age, not a birth date; the exact date of 6 March 1883 cannot be checked here; The list gives previous residence, not birthplace, so Mostiště as the place of birth is not stated; The departure date is not visible on this page, so the birth year implied by the age cannot be calculated exactly; The handwriting of the age and place name is faint and the readings are uncertain
