Yang is Cinder's and Qrow's daughter. Cinder went evil and broke up with Qrow. For Yang's safety, Qrow hid her with "Summer Xiao Long" who had a fire semblance and thus was a beliable mother for Yang. Since Summer is "officially single", Yang gets her maiden surname. Later, Summer marries a "Mr. Rose" and takes his surname as married name. Mr. Rose has a speed semblance Ruby inherits, alongside his last name. Once again, Monty has stated that Ruby and Yang are "blood-related," as in not adopted or step-sisters. That contradicts your theory that Yang is Cinder and Qrow's daughter and Ruby is the daughter of Summer and "Mr. Long/Rose."
