I'm thinking of changing my name to...?

Abigail is a name I have always loved and since I'm of age now I want to legally change it. What middle name/names would you suggest as well as last name? Yes, I'm also changing my surname. I'm of Spanish descent and I'm also Jewish so I want something along those lines. (Please no common surnames like Sanchez, Garcia, etc.) And for those of you who will post things like don't change your name, changing you name is an insult to your parents, etc., I'm asking for help in searching for a name, not your opinion. Thanks to anyone who is willing to help.
