From the way Yang described Summer when taking to Blake, I get the feeling that both Ruby and Yang were raised thinking Summer was their mother, after all it wasn't till after Summer's death that Yang learned about her biological mother not being Summer. This seems to remove the idea of Yang and Rose using different last names because Summer and Taiyang maybe weren't married. As a child you would wonder why your last name is different that your sister's.

I think both of them went by Taiyang's last name and after Summer died, Ruby decided to use Summer's last name. Maybe she did it thinking that she was honoring Summer?

During Volume 1, my initial theory was Ruby was either a half sister, cousin or addopted stepsister, and that after Summer died Taiyang raised her because Ruby lacked any other parents and then making Yang and Ruby sisters with different last names. Of course that was proven wrong when we recieved more information.
