Wisconsin, U.S., Death Index, 1959-1997

Validator (claude-sonnet-5-5, 2026-10-28): consistent, confidence 1/4, tier index.
The page is a legible index of the Wisconsin death index. The entry 'HEJNAL, MARY' (cert 202278) has death date 04/25/1989 and county MILW, matching the date and county in the claim. However, the surname is Hejnal rather than Konecny, and no birth date or age is shown. Without further evidence that Mary Hejnal and Mary Konecny are the same person, this is a weak match on name, date and place, and the surname discrepancy needs explaining.
Matches: Entry 202278, death date 04/25/1989, matches 25 April 1989; Death county MILW and residence county MILW match Milwaukee County, Wisconsin; First name Mary matches the claim
Flags: Surname on the index line is HEJNAL, not Konecny; this could be a different person or a maiden/married name difference
Limits: The index lists no birth date or age (the columns are blank), so the 1903 birth year cannot be checked; Nothing on the page links this HEJNAL entry to Mary Konecny; the surname difference is unexplained; This is an index page, not the original death certificate; it names no parents or spouse; The page lists only the county, not the city of death
