1930 United States Federal Census

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 1/4, tier record.
The image is a readable 1930 census page, and the Czechoslovakian household of George J. and Frances fits the likely target. The surname appears as something like 'Touska' rather than Tauber, and nothing links the household to the Tauber family. At best the record is consistent with a Czech woman named Frances, so the name claim needs other evidence.
Matches: Sheet 2A, ED 38-151, San Francisco matches the citation's page, enumeration district and place; Lines 38-43 list a Czechoslovakia-born household: George J. (head), Frances (wife), and children George, Emma, Sylvia and James; Frances is a Czech-speaking, Czechoslovakia-born wife, a plausible English form of Františka; Her age looks like the mid-to-late 40s, which would fit a birth around 1883, though it is hard to read
Flags: The head's surname looks like 'Touska' or 'Tousha', not clearly Tauber, so this family may not be the Tauber family; The citation does not say which household is the person of interest, so the link to Františka Tauber rests on first name and ethnicity only
Limits: A census gives a given name and a married surname, not a maiden name or birth date; Wife's age and immigration year are small and hard to read in the image; No dates or places in the record can confirm the 1883–1955 lifespan; Nothing here shows that Frances is Františka Tauber specifically
