Cook County, Illinois Marriage Indexes, 1912-1942

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 2/4, tier index.
The image is a readable page of the Cook County Marriage Index, 1914–1942, with a groom entry for Konecny, Petr J, and bride Anna Tauber, 22 Feb 1919. The surname and first name fit the claimed Petr Konečný. The middle initial J does not match Pavel, and the index cannot prove the full name. It is consistent only as a name variant, and it needs the spouse and date to be confirmed elsewhere.
Matches: Index line reads GRM KONECNY, PETR, initial J, married BRD TAUBER, ANNA, 02-22-1919 (serial 0819912); Surname Konecny matches Konečný and the first name Petr matches; Bride Tauber is a Czech surname and fits a Czech family context
Flags: The middle initial is J, but the claimed name is Petr Pavel, which would give P; Nothing on the line confirms that this Petr is the same person as the one born in 1893
Limits: The index gives only a name, initial, spouse, serial number and date, so it cannot establish the full name Petr Pavel; It gives no age, birth year, parents or birthplace; The index is a transcription, so the spelling is the indexer's and the diacritics are lost; Identity depends on the spouse and date matching other evidence in the database
