U.S., World War I Draft Registration Cards, 1917-1918

Validator (claude-sonnet-5-5, 2026-10-28): partial, confidence 3/4, tier record.
The image of the original card is readable and gives Vaclav Taubr, born November 17, 1876, age 41, which matches the claimed birth date. The card does not record a birthplace, so the claim of Mostiště, Rokycany is neither supported nor contradicted. The birth date is supported; the place needs another source.
Matches: Name "Vaclav Taubr" matches Václav Tauber (Czech/German spelling variant); Date of birth written as November 17, 1876, matching the claimed birth date; Age 41 is consistent with a 1876 birth at registration on Sept 12, 1918; Registered in Cook County, Illinois (Chicago); naturalized citizen, consistent with a Bohemian immigrant; Wife listed as Francis (Františka), living at the same address
Limits: The card has no place of birth, so Mostiště, Rokycany, Bohemia is not shown; The card gives no information about parents or origin beyond naturalized status; The registrant is identified only by name, date of birth and wife's first name; no other fact ties him to the claimed Václav Tauber (1876–1956); The registration date is hard to read (Sept 1x, 1918)
