Nice names all of them some much more popular than others.
Lucy - nice, and could be a nn for Lucinda. I also like LIndy and Lucia. All of these could be nns so it's versatile.
Florence - quite harsh, much prefer Flora for short, but as it was your grandma's name, you probably want to use Florence itself. There aren't too many out there I don't think, it's too strong to become really popular I think.
Daisy - I like this, I also like Posy.
Amelia - pretty, there are a fair few of them though.
Annabel - lovely, makes a nice change to hear this instead of Isabel. Annabel could be a sister to an Amelia or a Florence. I know an Annabel, but it's definitely rarer than Amelia.
Charlotte - not crazy about Charlotte but I love the nn Lottie.
I prefer Beatrice to Florence, and in the same style as all of your beautiful elegant names I like Juliet, Louisa, Phoebe and Claudia.
