This Russian patronymic of BORING was derived from the name BORISOV which was from the popular given name BORIS. The name was composed of the element BOR (conflict), and from the personal name BOGORIS which was borne by the king of Bulgars (sometimes known as BORIS) who was converted to Christianity in 864. This is a byname from the Turkic BOGORI. The name is one of the few non-Byzantine names used as a baptismal name in the Orthodox Church, largely because of the popular cult of St. BORIS (died 1010) the patron saint of Moscow. The name has occasionally been adopted by Jews. Other spellings of the name include BORISVICH, BARYSEVICH, BORYSIEWICZ, BORISYAK, BORIN, BORISCHEV and PORZIG. Many of the family of BORISOV served the Russian Throne in noble positions, and were granted fiefdoms in 1603 and other years. Descendants of this family Vasilii, Nechai, Mikhailo and Roman BORISOV in 1537 were granted a charter for the hereditary estate of their father BORIS, son of Matvei, by the great Prince Vasilii Ivanovich. In the same way others of this family served the Throne in various noble positions and were granted villages. Dmitrii BORISOV of the Company of Life Guards by the command of Her Highness Empress Elizaveta Petrovna, dated December 31st, 1741 was granted the rank of nobility along with all his legal descendants. Russian surnames are almost exclusively patronymic (occasionally metronymic) in form, usually ending in 'ov' or 'ev'. Habitation and topographic names are rare, and many common Russian surnames are polygenetic, and their literal meaning is clear, even though the reason for their adoption may not be. Heraldry appeared later in Russia than in most other Western European countries. It is generally agreed that it was copied from the west sometime in the late 17th century, and quickly achieved state significance. In 1722 Emperor Peter I (The Great) established an official Heraldry Office headed by a Master of Heraldry under the jurisdiction of the Senate, and granted 355 armorial bearings in the 18th century.
