A Beautiful Middle Name For Anastasia ?

I Love The Name Anastasia ( Pronounced Ana-STAH-Sia Instead Of Ana-STAY-Sia)But I Need A Good Middle Name For It. I Cant Decide If It Would Be Better To Have Another Long Name Like Natalia Or Esmeralda , Or A Shorter Name Like Grace, Rose , Or May ? Also , Can You Suggest Some Other Possible Names/Middle Names ? Thanks In Advance xxx
