guys and gals, I think we have get the clue, the name has some similiarity,

Ruby= Red diamond, reffering to red

Weiss= White

Blake= almost like Black, so it mean black in this case

Yang= sun, reffering to yellow

so.. and the surname also has this similiarity, only in personality

Belladonna= fine lady, as a fine lady should, Blake didn't want to hurt innocent people

Schnee= snow, as we know, Weiss is kinda cold hearted

Xiao Long= little dragon, Yang is pretty much like a little dragon, having fun, aggresive, easily tempered

so... the clue for Ruby's surname is between an adorable, fierce, aggresive, prankster, funny, and goofy... that's for today...
