"the Branwen side of the Rose family" The Branwens are not related to the Roses. Yang is related to the Branwens, but Ruby is not. Ruby only calls Qrow "uncle" because, growing up, her older sister who, as far as she knew at the time, was her full-blood sister, was calling him Uncle Qrow. She was just doing what big sis did.

Even though the truth is out now, she's not gonna stop calling him her uncle. She considers him to be family.
