To make a nice name really nasty, add a y. I don't enjoy
Rowan for a girl, but it's a whole lot better than Rowyn!
I know a
Bronwyn - actually she's
Bronwyn Jayne! - who went to a conference once and was given a name tag in the usual way, except that someone unaccustomed to kre8iv spelling had entered her name as Brown
Wine Lastname.
And then there's
Annie ... as a mn. Weird.
