I've been reading a book called The Silver Age by Michael Shatiryan, translated to Russian by his daughter about the history of Armenian Cilicia during the reign of Ruben III, and of Prince/King Levon I/II, in the book there is a parallel story of an Armenian paron named Smbat, born in Artsakh, who had 10 sons. His wife's name is Nravd. Levon referred to him as his uncle, but i'm not sure of their relations, He might have been the brother of Stephen of Armenia. His possesians were Gouglak, and several other fortresses around it. If anyone has any information about this man let me know. This is the book http://www.armeniaonline.ru/product.php/1014.
