Group
Vrishnis
वृष्णि कुल
The Vrishnis are the leading clan of the Yadava confederacy: that branch of the Yadu line in which Krishna and Balarama were born; Satvata-Vrishni relations stand at the center of Yadava politics in tradition. SB 1.3.23: 'vrsnisu prapya janmani rama-krishnav iti' — the Rama-Krishna pair was born among them.

Their own destruction through drinking varuni
Permitted, the Vrishnis and Bhojas drank varuni, their knowledge shaken, and began to touch each other's tender places with harsh words; made uneven in mind by the fault of the maireya wine, they ground against one another at sunset — 'veNUnAm iva mardanam', like bamboos rubbing together (SB 3.4.1-2).
