Zelda is a whole lot better than Grizelda! It's got a good sound and a lively, modern feel. I like!
I do find
Rose trite;
Alexandra would be my knee-jerk preference. What about something a tad longer with
Rose as a nn -
Rosemary,
Rosamond,
Rosalind,
Rosalie ... I once knew a woman named
Dorothy Perkins whose nn was
Rose.
Rita - dated and a bit dusty, but energetic and unpretentious.
Margaret "
Meg" - I like
Margaret a lot, but
Meg isn't the most obvious nn at present. She and/or you would have to take a very firm stand against the
Maggie brigade.
Mary - calm and quiet and due for a comeback.
Emma - feeble and silly and over the hill.
Stanley - once I knew a
Stamatios who was known as
Stan. He's in his early 40s now. All the Stanleys I've ever known are or would have been over 80. I don't mind it, but I'm not sure it's due for a comeback.
Kian (or
Kean /
Cian?) - see below
Keenan - Yuck. So trendy and flimsy.
Caleb - always sounds comical to me; never seen or heard it used where I live.
