I wasn't sure where to put this, but a good set of names for twins is Callista and Victoria. Put together, they mean Most Beautiful Victoriy. Other variations, such as Linda and Victoria (Beautiful Vicotory) and masculine forms of the names work too. I don't know a masculing form of Callista or Linda, but there must me some masculine names meaning Beautiful, and it's Victor for Victoria. Another good set of twin names works only for two girls: Melodie and Harmony. I guess that's just my two cents.
