Etymology OF Dogra dynasty
The term Dogra is thought to derive from Durgara, the name of a kingdom mentioned in an eleventh century copper-plate inscription in Chamba. In medieval times the term became Dugar, which later turned into Dogra. Kalhana’s Rajatarangini makes no mention of a kingdom by this name, but it could have been referred to by its capital (ether Vallapura, modern Balor, or Babbapura, modern Babor). In modern times, the term Dogra turned into an ethnic identity, claimed by all those people that speak the Dogri language.
The family of Raja Gulab Singh is referred to as Jamwal (or Jamuwal). According to some accounts, Raja Kapur Dev, who ruled the area of Jammu around 1560 AD had two sons named Jag Dev and Samail Dev. The two sons ruled from the Bahu and Jammu on the opposite banks of the Tawi River and their descendants came to be called Bahuwals and Jamuwals respectively. The members of the family however claim descent from a legendary Suryavanshi (solar) dynasty ruler Jambu Lochan, who is believed to have founded the city of Jammu in antiquity.
