Oh. Poor you. I feel your pain.
My two cents on nns: Formal names are the place to show education / meaning / honor, etc. They are like wearing your best outfit to a job interview. It's how you present yourself to the outside world.
Nns, on the other hand, are the place to express creativity, affection, whimsy. They are like the comfy pair of jeans you slip into when you come home from the interview. You don't need to dress up around those at home who already love and admire you. It's the same with nns used by loved ones.
So
Rosalie, nn
Flower Pot, makes sense to me. Zalia from
Rosalie is pretty tame in my world. :-D
I've always loved the French name / nn Zelie ("ZAY-lee," with an accent going up over the first "e"). You might like that one / spelling too. [My research has unearthed many sources for Zelie, the most likely one from the French word for
Azalea. So it's not that far off from Zalia.]
Other possible nns from
Rosalie:
Rosa (an surprisingly underappreciated classic)
Rosaleen ("My Dark
Rosaleen" is a poem about
Ireland)
Ro
Ree (Did you ever see "
Winter's Bone" with
Jennifer Lawrence?)
Lee (clean, clear and bright)
SallyR.V. (just kidding)
V. / Vee
LisaLior /
Liora (rearranging some of the letters in
Rosalie)
