Kashyapa Rishi is their earliest ancestor and their sons are called as Kashyapai lived in Kaskikot, now in Kaski, Nepal.

When Kashyapai moved to Ujjain, in the Malwa Region (now in Madhya Pradesh India), they took the surname Bias (or Vyas).

Gudpal Bias entered Western Nepal through the route of Kumaon, Garhwal and Jumla from Ujjain.

Gudpal Bias was the royal priest of King Vikramaditya, who ruled Ujjain, an ancient city in central India.
