On his writings of the 11th-century historian Asoghik wrote that Samuil had only one brother. According to Asoghik who lived in Derjan, located in an Armenian region of the Byzantine Empire, Samuil was also from Derjan and had Armenian origin.
Asoghik version is supported by the historian Nicholas Adontz who analyzes in depth the events and facts of the century and comes to the conclusion that Samuil had only one brother – David.
