RISHI BHARGAVA
Bhargav or Bhargava is a surname of Brahmins whose Gotra is Bhargav. That is, those who are descendants of Muni Bhargav. A Sanskrit saying states that Bhrugu jaayate iti Bhargav, which means that all those born of Bhrigu are Bhargavs.
Bhargava is another name for Parashurama, one of the 10 incarnations of Lord Vishnu. He is the son of Sage Jamadagni & Renuka. He was a manifestation of the ultimate divinity's need to balance 'dharma' and 'adharma' (harmony and disharmony) and consequently visited justice on many kings who had been abusing their power or had lost a hold on their ethics as protectors of their dominions. His time of activity comes to a close when he encounters Lord Rama (another of the avatars of Lord Vishnu).
