Righteous Gregory of Samara (identity unconfirmed)
The entry "Gregory of Samara" is not confirmed by any source as a distinct, genuinely venerated saint connected to Samara; a targeted search (including a check of Samara's new martyrs and hierarchs) found no matching figure.
A targeted check of azbyka.ru, pravenc.ru, drevo-info.ru, ru.wikipedia.org, and specialized sources on the new martyrs of the Samara diocese (lists of repressed clergy, the official website of the Samara Metropolia) found no saint, bishop, elder, or new martyr named Gregory locally venerated in connection with the city of Samara. The only similarly-sounding find is the Hieromartyr Deacon Gregory Samarin, who suffered in 1937 — but he belonged to the Kolomna/Moscow diocese, and the coincidence of the surname "Samarin" with the toponym "Samara" is purely accidental. In the absence of a confirming source, this entry is marked as an unconfirmed identity and disabled from calendar display.
