This is the 1840s confirmation record of a Russian convert to Catholicism. The names of his parents back in Kamchatka, probably orally reported to the Spanish-speaking priest who wrote in the register book, are recognizably Russian except for the word that resembles Macorís.
I haven't been able to find any similar name or surname. Is it after all Russian?
Jose Bolcoff [Осип Волков]. Son of Jacobo Bolcoff [Яков Волков] and Ana Macorís [?]. Godfather Francisco Soria.
