I'll always think of VivienLeigh's Scarlett O'Hara saying "Oh, Mamie" in a whiney voice when I see the name. I prefer MamieOlivia out of the combo's listed.
I think there is a difference in pronounciation though. In GWTW, I believe it was Mammie pronounced like Whammy, whereas I think the name Mamie is prounouced like Amy.
This is true, but with some accents (esp. in the United States) the prn. is still the same."No one can make you feel inferior without your consent." -EleanorRoosevelt
