Alternately, there is the meaning behind the name that I picked up from Kabalarians.com. My comments on the definition are in red.

      ' The name of Dorothy creates a happy, versatile, and expressive nature, (Dorothy? Not the bishoujo I remember...) with good business judgment (I'll grant them that one.) and a fine sense of responsibility, which should enable you to establish congenial relationships in positions of trust where you are dealing with the public. (Fair enough. Both Relena and Zechs seem to trust her rather quickly.) You have a clever, quick mind, (Definitely.)with the ability to accomplish a great deal in a short period of time, (Uh-huh.) although it is not easy for you to systematize your efforts. This name could allow expression along musical and artistic lines (Is fencing an art?) and gives you the desire to entertain and to meet and mix with people of refinement and culture. (Of course. She is part of Romafellar, after all.) It also brings out your love of home and family, (It is her love for her father that made her crazy about war after his death.) and in close association you are able to show understanding and affection. (Well, Quatre said she was kind...) Others are attracted by your generosity and your consideration of their interests. (Don't think so.) Although this name is well balanced, if it is combined with a surname that is not harmonious, (Is Catalonia harmonious?)  you would tend to worry and find it difficult to organize your efforts. Also, should you over-indulge in sweet, rich foods you could experience skin or liver problems. ' (Dorothy: I want chocolate! Nownownow! ^_^;;;)
