The Hamburg emigrant list (Band 147, page 2439) shows 'Tauber, Anton', male, age about 17, Austrian nationality, with a former residence that looks like 'Kostitz'. Anton is the standard German form of Antonín, so the record states the claimed name. The next line, 'Franzisca', about 20, may belong with him, but the bracketing is unclear. Linking this traveler to the database person rests on the name and an age roughly matching 1887; confirm the list's sailing date and the residence reading against his known birthplace.
Matches: Right-hand page, near the bottom: surname 'Tauber' with given name 'Anton', the German form of Antonín; Marked male, age about 17, which fits a birth around 1887 if the list dates from about 1903–1904; Nationality column reads 'Oest' (Austrian), which fits a Czech-lands emigrant before 1918; Former residence appears to read 'Kostitz', possibly Kostice in Moravia; the reading is tentative
Limits: The departure date and year are not visible on this page, so the age cannot be firmly converted to a birth year; An emigrant list gives a name and age only; it does not prove this Anton Tauber is the Antonín Tauber (1887–1939) in the database; The residence entry is faint and only tentatively read, so the place link to a known home village is unconfirmed; The record gives the German form 'Anton', not the Czech 'Antonín'
