Righteous Euphemia of Alexandria (identity unconfirmed — contamination)
The entry "Euphemia of Alexandria" is not confirmed by any source as a distinct historical saint; all three listed feast dates (Sept 16, July 11, June 2) belong to a different, well-known saint — the Great Martyr Euphemia the All-Praised of Chalcedon.
A targeted search of azbyka.ru, drevo-info.ru, pravenc.ru, ru.wikipedia.org, and days.pravoslavie.ru found no distinct, independently attested saint "Euphemia of Alexandria." All queries lead either to the Great Martyr Euphemia the All-Praised (of Chalcedon) or to an entirely different saint, Venerable Euphrosyne of Alexandria (who lived disguised as a monk, †c. 445/470). The dates September 16 and July 11 are documented feast days specifically of Euphemia of Chalcedon: September 16/29 is the day of her martyrdom under Diocletian (c. 303-304), and July 11/24 is the "Commemoration of the Miracle of the Great Martyr Euphemia," related to the role of her incorrupt relics in resolving the doctrinal dispute at the Fourth Ecumenical Council in Chalcedon in 451. The pravenc.ru article on Euphemia of Chalcedon mentions, in its scholarly apparatus, the historian Tillemont's hypothesis that a reference by St. Asterius of Amasea might concern "another martyr Euphemia, possibly of Alexandria" — but explicitly labels this an unconfirmed speculation, not an independently attested saint. The date "June 2" does not appear in any standard listing of feast days for saints named Euphemia (January 17, April 2, May 29, July 24, December 2) and appears to be an additional data-entry error. This entry is therefore pure name-contamination from Euphemia of Chalcedon rather than a distinct saint. No images were attached to this entry.
