I do not think I would change... because my name is equal at name of my dad. But if I would change, maybe I would can put the name of my grandfather, but your name is already my last name.
Maybe I'd keep my name the same but legally change it to "Return to Sender" to stop getting so much junk mail
When I was a kid, I didn't like my name as it is boy's name. Everyone who knew my name before meeting me always mistakes me to boy :( So I kept asking my parent why they gave me this name and wanted to change my name. But now, it doesn't bother me anymore since I knew the meaning of it. "Trung Anh" means loyalty, couragement and elegent in Vietnamese. In addition, I realize that my name is really uniquely special as I haven't found any girl having the same name as me ^^
I would like to change it to MACOWIEN! :D
My name is awesome, speaks a lot about my personality hehe.
