Britney Spears called her son Jayden as did Will Smith, with what precedent I do not know (as if there needs to be a precedent with celebrities!)

The most unusual name in my family tree from the 18th c is Kezia (f) which actually sounds like a modern made up name to me!I also have a Martha who was known (to family still living) as Patricia...this caused lots of problems trying to match up families on the census returns as know one knew her real name was Martha. Marje is quite correct about the reasons why...a small pool of names used which could cause confusion without varients/diminutives.

In my experience a lot of older names have come back into fashion Molly, Lily and Florence being particularly popular. My neighbours kids are called Stan and Charlie. Im waiting for Edna and Doris to come back too :-)
