There is no exact date of construction of the church in Drohiczyn. Therefore, we will start from the oldest documents found on it. Perhaps the earliest document mentioning the church in Drohiczyn is the mention in “In the list of Christian Catholic settlements in 1726 is mentioned Dorochyczyn Oppidum”. Further, there are Uniate metric books in RGIA from 1760 to 1798. Also worth noting are the Uniate metrics for 1823 at Marmon.

The earliest mention of the church in Gniewczyce can be considered the book “Mironowicz A.: The Turaŭ-Pinsk bishopric in the 11th-16th centuries. Trans Humana, 2011.” Where in the Turow-Pińsk Biskupstvo the paraphyses in the XI-XVI century are described, the Gniewicz paraphy is also mentioned. The church after the signing of the Unia was converted to Greek Catholicism, which is confirmed by the preserved metric Uniate books in RGIA for 1800-1801.

Gorki was part of Drohiczynski County, so it is worth mentioning the local church. The exact date of its foundation is not known, but we will start from the oldest documents, which are available for this church. Gorki is mentioned in the list of Christian Catholic settlements from 1726. RGIA has copies of the Uniate metric books of the Horeckiey church from 1748 to 1801. There is also a mention of Gorki in the Uniate metric books of the Ilyinska church in 1774-1822.
