Barbara: Of course, he received his name at birth and was then bitten by a
werewolf as a child.  Perhaps his parents should have thought better of the
name they gave him.
If ever someone's destiny were in his name...

I've noticed that names often reflect the personalities of their owners.
Could it be that wizarding parents name their children when they have a
better idea of the child's personality? I know Voldy was named right away,
but his mother was dying. But then, there's the problem of what to call
children if they are babies, if they don't have a permanent name till
childhood. This question comes to mind because I hear Native Americans do
that. Children are given temporary names until more of their character is
known, so they get a fitting name. Actually, I'm not sure if this is still
practiced. I know it *was* a century or two ago.
