I thought that some guy (this is all fuzzy, but it was some guy, centuries ago) insisted that good nicknames could be created by adding an N to the first syllable to given names. Thus
Ned,
Nell,
Nan, and other ones that fell by the wayside, like
Noll (from
Oliver).
But since I can't remember it well, this isn't meant to be taken as fact, mind. :)
