Olive

Olivia came after Olive (it's only been in common use since the 1600s), and it has a "v", so that's not quite the same. Not sure what point you were trying to make.

Actually, this word is ultimately derived from Greek "elaia," from which Latin "oliva" is derived.

The olive has long been a symbol of peace. For example, the olive was sacred to Athena, the Greek goddess of peace; in the Bible, a dove brought Noah an olive branch to demonstrate that the flood was over, and the olive tree, olive oil and the olive itself play many other important roles in the Bible; the olive signified "peace" in the Victorian language of flowers; etc.
