Overview
A transcript from the design document describes the concept for the tribe, seen below.

Fallout: New Vegas
The Twin Mothers tribe was mentioned by Ulysses as formerly one of the tribes that were located in the eastern Mojave Wasteland. According to Ulysses, they were known for creating a powerful morphine-like medicine called bitter drink. The medicine was regularly used by Legion soldiers during forced marches of wounded soldiers, which helped greatly during their travels through Crimson River Trail. According to Ulysses, the Twin Mothers were always about teaching lessons, and that Caesar taught them their last, implicating that they were destroyed and absorbed.
