Transcription and reasoning
Validator (claude-opus-5-5, 2026-10-28): supports, confidence 3/4, tier index.
The card image is clear. It reads Konecny, Joseph, of 1424 N. 19th St., Milwaukee, Wis., born Feb. 17, 1901 in Czechoslovakia, naturalized Feb. 15, 1940 in the Circuit Court of Milwaukee County, certificate CN-4803730. It explicitly states the claimed naturalization date, and the birth date fits the 1901 birth year. Because it is a contemporaneous index card rather than the petition itself, confidence is 3 rather than 4.
Matches: Family name 'Konecny', given name 'Joseph', matching the claim; Date of naturalization typed as 'Feb. 15, 1940', matching 15 February 1940; When born: 'Feb. 17-1901', matching the claimed birth year 1901; Country of birth or allegiance: Czechoslovakia, consistent with a Czech surname; Court: Circuit Court, Milwaukee Co., Milwaukee, Wis.; address 1424 N. 19th St., Milwaukee; certificate CN-4803730 (P 36692)
Limits: This is a Soundex index card (K 525), not the naturalization petition or certificate itself; No arrival date or port, and no witnesses, are recorded on the card; The card cannot confirm the claimed death year of 1985; The citation detail names the Northern District of Illinois / INS District 9 series (M1285), while the card is for a Milwaukee, Wisconsin court. This is plausible because Wisconsin courts fell under INS District 9, but the petition itself would need to be pulled from the Milwaukee County Circuit Court records
