源氏
The Hatano and Matsuda families originally sided with the Minamoto clan, and Hatano Yoshimichi moved to Kyoto and served for Minamoto no Yoshitomo. After the Hogen War in 1156, however, he ended up being forced to kill Minamoto no Tameyoshi, Yoshitomo's father and the former lord, which made him fall out with Yoshitomo and go back to Sagami Province. This was the way they took sides with the Taira family when the Minamoto clan fell.
