1930 United States Federal Census

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 3/4, tier record.
The image of the 1930 census shows Joseph as head of household on line 98, married, aged 28, a welder at a steel company, in Milwaukee Ward 9. This matches the residence, relation, marital status and occupation in the claim. The only gap is that the surname is not written on his line and is inferred from the adjacent Konecny household.
Matches: Line 98: Joseph, relation 'Head', in dwelling 20, family 25, Milwaukee Ward 9, ED 40-112, which matches the citation's ED 0112; Marital status 'M' (married), with wife on line 99 (age 26) and son Robert on line 100; Occupation 'Welder', steel company, as in the claim; Age 28 on April 1930 implies a birth year of about 1901–02, consistent with 1901; Born in Austria, mother tongue Bohemian, and a sheet 'B' in a Milwaukee ward. These fit a Czech-origin Konecny family, and the Konecny family (Frank, line 93) is enumerated just above
Limits: The surname is not written on line 98. It appears to be left blank, so 'Konecny' is inferred from the preceding household (Frank Konecny, dwelling 19); A census age gives only an approximate birth year, not a date; The record does not link this Joseph to the 1901–1985 person's later life; that link depends on other evidence; The image resolution makes the wife's name and the immigration year hard to read, but neither is part of the claim
