Gotra
Gotra is a clan in Hindu society. It means the people who are descended in an unbroken male line from a common male ancestor. In the 4th century, Pāṇini wrote that gotra are the descendants of a sage, "beginning with the son's son."(IV. 1. 162). A person who says "I am Kashyapa-gotra," can trace his family from the ancient sage Kashyapa through an unbroken male line.
