Hieromartyr
Hieromartyr (?) Demetrius Kedrov (identity not reliably established)
XX в. (предположительно)
The card "Demetrius Kedrov" — honestly flagged as uncertain: no canonized New Martyr with exactly this name and surname could be found; the previous date turned out to be borrowed from Great Martyr Demetrius of Thessaloniki and has been removed.
HONEST NOTE ON THE ABSENCE OF RELIABLE IDENTIFICATION: a careful search of standard New Martyr databases (drevo-info.ru, azbyka.ru, pravenc.ru, the pravoslavnoe-duhovenstvo.ru clergy database) did not turn up a canonized "Hieromartyr Demetrius Kedrov" under exactly this name. The previously listed date "October 26/November 8" exactly matches the feast of Great Martyr Demetrius of Thessaloniki — apparently mistakenly borrowed by coincidence of the given name, not individually researched for this person; the date has therefore been removed from the card rather than retained as falsely authoritative.
The search turned up several REAL but NOT identical candidates who may be the source of the confusion: Hieromartyr Sergius Pavlovich Kedrov (archpriest, shot at the Butovo firing range November 16, 1937 — correct surname, but a different given name); Hieromartyr Averky (Kedrov, born Polikarp Petrovich), Archbishop of Volhynia and Zhitomir (shot 1937, glorified by ROCOR in 1981 — surname matches, but given name differs); Hieromartyr Dmitri Vasilyevich Kedrolivansky, a priest from Egoryevsk (1890–1938 — given name matches, but the surname differs, "Kedrolivansky," not "Kedrov").
The card has been retained in the database with an honest note of uncertainty, rather than assigning it a fabricated biography of one of these real but non-identical people. Category and regional affiliation have been left undetermined pending archival confirmation (e.g., via the PSTGU "Memory Fund" database, which was inaccessible at the time of research).
