Pr. Pokrovsky

A person referred to only by the unexpanded abbreviation "Пр" (possibly a title such as "Prot."/"Protoiereus," a first name, or another abbreviation not resolved by this letter) plus the common surname Pokrovsky, who asks -- relayed via Kolomnin -- that Alexander send him his photograph. A common surname shared by several other unrelated, likewise-unidentified Pokrovskys already distinguished in this corpus (the Taganrog priest;, thanked by Kolomnin for a tea-glass holder;, from a newspaper advertisement;, an orator) -- kept as a separate provisional entity pending further identification, not merged with any of them.
