The image shows the household of Elizabeth Tauber in Chicago, with Alois (27), wife Irene (26) and son Alois R. (2) on lines 68-70. This matches the claimed residence, place, year and family members. The index spelling 'Tarber' is a misreading of Tauber.
Matches: Image is the 1940 census, Chicago, Cook County, Illinois, Ward 15, ED 103-1020, sheet 8B, matching the citation detail; Line 68: Alois Tauber, son in the household headed by Elizabeth Tauber (line 65), age 27, married, born Illinois, pressman in printing industry; Line 69: Irene, daughter-in-law, age 26, born Illinois; line 70: Alois R., grandson, age 2, born Illinois; Age 27 gives a birth year of about 1912/1913, consistent with Alois Joseph Tauber b. 1912; Surname is written Tauber on the sheet; the index reading of 'Tarber' is a transcription variant; Supplementary line 68 also lists Alois Tauber, with parents born in Illinois
Limits: The census gives no middle name, so 'Joseph' is not confirmed; Age implies a birth year, not an exact date, and does not confirm the 1912 birth; Whether this Alois is the same person as the database individual rests on the match with wife Irene and son Alois R.
