New episode gave new info. Qrow, as Yang referred to him as "our uncle", must be their father's brother. They were on a team with Summer and Yang's mom, Yang's mom left her with her dad when she was born (it happens), and Summer must have raised Yang before she died because Yang called her "our mom" before revealing she and Ruby had diffrent mothers.
