what is my full name and was I named for someone?

My full name right now is Dorothy Anne Walker.. My maiden name was Gagnon. I also went by the name of Graves for 9 years. I was named after my Mom.. but she never used my name.. Her name was Dorothy Viola Gagnon, but during her teens everyone called her Viola, so she went along with that.. You can imagine my surprise when I saw it on her legal documents, and we had quite a conversation about it.. Back then nicknames really stuck..
