Hm. I do like it with the nickname
Zelda, but I'm having a bit of a tough time with the Gris- beginning sound. It rather stongly reminds me of Gristle, Grizzly, etc. It's a harsher sound, and that's contrary to my style of female names.
Overall, it's not my style, but I don't hate it - and I think
Griselda Rose is a good combo. I think it needs something softer in the middle name slot to sort of soften the harsh first syllable.
