It is more of a habit, than a rule, that one part of a married couple takes on the name of his/her partner. Sometimes, they just keep theirs.

Raven (if she is Yang's mother) and Summer most likely agreed with Taiyang to keep it that way. The surnames of their daughters might also be an agreement between him and his beloved; Yang being given his and Ruby given Summer's.
