Not gonna get into the details as to why that is, but it does happen. =) Damn now I'm curious. It's actually quite a rare occurence for (full) blood siblings to have different surnames outside of marriage, legal issues or out of choice actually unheard of to me until now,

Neither of which seem like they apply to Yang and Ruby unless Ruby's name was changed for protection reasons following the death of her mother, but then surely so would Yang's... Why would it be Ruby's name that changed? After all, the grave stone that Ruby is seen standing in front of in the Red Trailer, as well as kneeling in front of in the intro, is marked "Summer Rose".

Because it doesn't seem like Yang is particularly distraught about the death of Summer and the little we know of Summer (such as from Red Like Roses Part II) hints at a particularly close connection to Ruby with a desire to protect her from someone or something. I don't even think it is a legal thing, there are too many holes in the theory.
