A lot of people are loving the name "Sarangdhar" the character too of course. Bt I doubt anyone knows about the meaning & origin of its name. I will clarify it here & how the character is connected to its name #Story9MonthsKi
Sharang is actually the name of Dhanush
of Bhagwan Vishnu & of course of his poorna-avtar Bhagwan Krishna. Since he holds Sharang (dharan karna), he is known as "Sharang-dhar" or in common local language "Sarangdhar". So basically Sarangdhar is another name for Krishn/Vishnu

Since the character Sarangdhar belongs to Mathura so it is quite understandable that the choice of name will be revolving around principle deity of Mathura/Vrindavan. #Story9MonthsKi
