If Raven and Qrow are siblings you need to answer the question, 'Why are Yang and Ruby's last names different?'

One theory, as someone stated before, is a male dominate culuture whereas the first born is named after the father and the second the mother. Just so happens Yang's mom gets screwed because she happened to give birth to the first born of a man. I am not a fan of this method and also if this were the case one would assume the last names of Qrow and Raven would therefore not match because one would be first born and the other second.

Second theory, marriage exists and the woman takes the last name of her husband. Then Yang's mom and Taiyang would have been married hence Yang's last name and Taiyang just never married Summer hence Ruby was named after her birth mom in this case. One then just assumes that Raven is unmarried and is sister to Qrow or married to Qrow.

Third theory, last names don't matter and never change. Married or not when one has a child the couple just determine the full name of the child and whose last name they take. In this way you can make any sort of speculation on who is related to who and in what way.

Also I thought RT confirmed Cinder's age was only 2-3 years older than team WBY? I'm not basing Raven looks on age and granted we only have seen her for 30 seconds she just doesn't carry a motherly vibe about her. I could totally see aunt or sister though.
