Cook County, Illinois Marriage Indexes, 1912-1942

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 2/4, tier index.
The page shows GRM KONECNY, PETR J, with bride TAUBER, ANNA, serial 0819912, dated 02-22-1919. Name, date and county match the claim. The middle initial J versus Pavel and the lack of identifying details keep this at consistent rather than fully supporting.
Matches: Entry reads GRM KONECNY, PETR, initial J, with BRD TAUBER, ANNA, serial 0819912, dated 02-22-1919; Date 22 February 1919 matches the claim; Cook County Marriage Index, so the place matches Cook, Illinois; Surname Konecny is a variant of Konečný, and Petr matches the claim's given name; Bride Tauber matches the Czech/German name variants Taubr/Tauber
Flags: The index gives the middle initial as J, whereas the claim gives the middle name Pavel (P)
Limits: This is an index page, not the marriage certificate, so it gives no ages, parents or birthplaces; Nothing in the index ties this Petr Konecny to the 1893–1936 person except name and date; The index gives no place beyond Cook County, so the city is not shown; The middle initial J does not match Pavel, which may be an indexing error or a different usage; Dates in the index are in MM-DD-YYYY format and are read here as 22 Feb 1919
