The first Native Americans to become Russian Orthodox Church (later Orthodox Church in America) were the Aleuts (Unangan) living in contact with Russian fur traders (promyshlennikis) in the mid 18th century. Saint Jacob (or Iakov) Netsvetov, a Russian-Alaskan creole (his father was Russian from Tobolsk, and his mother was an Aleut from Atka Island) who became a priest of the Orthodox Church (he is the first Alaska Native Orthodox priest in Alaska) and continued the missionary work of St. Innocent among his and other Alaskan Native people. He moved to the Russian Mission ("Iqugmiut") on the Yukon River in 1844 and served there until 1863. Netsvetov invented an alphabet and translated church materials and several Bible texts into Yup'ik and kept daily journals.
