Staatsarchiv Hamburg, Hamburg Passenger Lists, 1850-1934

Validator (claude-opus-5-5, 2026-10-28): supports, confidence 3/4, tier record.
On the right-hand page (stamped Band 147), near the bottom, a family group lists 'Tauber Anton' (17), followed by 'Franzisca' (about 20), noted as his sister, with Austrian nationality and a residence that looks like 'Kostitz'. 'Franzisca Tauber' is the German form of Františka Tauber, so the record supports the name claim. The departure year is not visible on this page, so check it from the list header or index: the claimed 1883 birth fits only if this sailing was around 1903.
Matches: Right-hand page, near the bottom: a family entry headed 'Tauber' with 'Anton', age 17, male; Directly below is 'Franzisca' (German form of Františka), female, age about 20, apparently marked 'Schwester' (sister) in the family column; Both are listed with Staatsangehörigkeit 'Oest' (Austrian), which fits a Czech-born emigrant before 1918; Previous residence appears to read 'Kostitz' (or 'Hostitz'), a Bohemian or Moravian place-name form
Limits: The surname Tauber is written only on Anton's line; Franzisca's surname is implied by the family grouping, not written beside her name; The sailing date is not visible on this page, so the age of 20 cannot be checked against the claimed birth year of 1883; The record gives the German form 'Franzisca' rather than the Czech 'Františka'; A passenger list cannot by itself confirm that this woman is the person who died in 1955; The residence entry is hard to read on this dark microfilm image
