Gotra : Vatsa/Bhrigu

Wanted to know more about clan of this gotra. I belong to kashi and my family doesnt have much info about rajput clans. I only know that my father is of bhriguvanshi gotra as said by him and has "pratap" as surname. Also in purvanchal region I see majority dont have much idea about their clans, b/w majority dont even know their gotras!

So wanted to know what kuldevis, and which clan does this gotra belong to.

Any one who has gud understanding of this topic?
