U.S., Naturalization Record Indexes, 1791-1992 (Indexed in World Archives Project)

Validator (claude-opus-5-5, 2026-10-28): supports, confidence 3/4, tier index.
The imaged INS index card reads 'Konecny, Joseph, 1424 N. 19th St., Milwaukee Wis.' Naturalization was in the Circuit Court of Milwaukee County on Feb. 15, 1940, under certificate CN-4803730. The card gives birth as Feb. 17, 1901 in Czechoslovakia, so it states the claimed name directly and its birth date agrees with the 1901 birth year. Because it is an index card, the underlying petition (P 36692) would give fuller identifying detail. The card cannot confirm the 1985 death.
Matches: Family name typed 'Konecny', given name 'Joseph'; Born Feb. 17, 1901, which matches the 1901 birth year in the claim; Country of birth Czechoslovakia, which fits the Czech surname Konečný
Limits: This is a Soundex naturalization index card, not the petition itself. Names of witnesses, date and port of arrival, and parents are not given.; The card says nothing about death, so the 1985 end date is unverified.; The surname is typed without the diacritic (Konecny for Konečný). This is normal for U.S. records.; No independent detail ties this Joseph to the database person beyond name and birth date. That person's residence in Milwaukee (1424 N. 19th St.) would need confirming from other records.
