I've said this before but I'm not conviced that 'Rose' and 'Xiao Long' are family names, even if they are surnames. Historically, the two have not always been the same thing. Quite often, in ancient times, people were awarded or adopted surnames that reflected their personalities or what they wanted to say about themselves but these hand nothing to do with their families.

It's possible that, at least in Ruby and Yang's part of Remnant, family names are lineal descents, so their full names would be "Ruby, daughter of Summer of the Clan Vytal" and "Yang, daughter of Summer of the Clan Vytal" or something similar. 'Rose' and 'Xiao Long' were possibly given to them by their first instructors after discovering their Semblances.
