Surname names are popular, and I have a new one to consider for a girl: Middleton.
The rhythm and sound are similar to Madison, and Middie is a workable nickname, and now there's a nice princess association because of Kate Middleton---without the name being at all "princessy."
What do you think? Remember, the point of a "name to consider" isn't so much "Is this name to my own personal tastes?" as it is "Does this seem like A NAME, with potential for use by people whose naming style it WOULD be?"
