Pomortsy

Pomortsy (Russian: Поморцы), also known as Danilovtsy, Danilov's confession, Pomorians (not to be confused with pomors), or Pomorian Church was a confession of the Bespopovtsy (the "priestless") strain of Old Believers. It was founded in the end of the 17th century in Russian Karelia, by the Vyg River (Russian: Выг), by Danila Vikulin and the Denisov brothers. Initially Pomortsy denied the sancticity of tsar and marriage. Later they were split into Novopomortsy ("New Pomortsy"), who recognized marriage, and Staropomortsy ("Old Pomortsy"). They also spun off the confessions of Filippians and Fedoseyans.
According to 2001 data, in Lithuania there are over 27,000 Old Believers in 59 officially registered parishes of the Pomorian Church.
