I feel like [name]Beatrice[/name] would be a perfect fit with the other two names.

[name]Hi[/name]!
I love [name]Marigold[/name] and [name]Olive[/name]! I think both are great as is, and I don’t know if you personally use nicknames with them, but I would find another similar name that has nickname potential like your girls’ names ([name]Marigold[/name] - [name]Maggie[/name], [name]Goldie[/name], [name]Mari[/name]; [name]Olive[/name] - [name]Ollie[/name], [name]Liv[/name], [name]Livvy[/name])…
[name]Brier[/name] = [name]Brie[/name]
[name]Hazel[/name]
[name]Hyacinth[/name] = [name]Cynthia[/name] - [name]Cindy[/name]
[name]Iris[/name]
[name]Jessamine[/name] = [name]Jesse[/name] - [name]Jessie[/name] - [name]Jessa[/name] - [name]Minnie[/name] - [name]Mina[/name]
[name]Juniper[/name] = [name]June[/name] - [name]Junie[/name] - [name]Peri[/name]
[name]Lavender[/name]
[name]Primrose[/name] = [name]Rosie[/name] - [name]Rose[/name] - [name]Rosa[/name]
[name]Saffron[/name] = Saffy - [name]Ronnie[/name]
Or, another different nature name, like [name]Wren[/name] or [name]Lark[/name], could work very well!
Good luck!

[name]Marigold[/name] and [name]Olive[/name], so adorable! Your daughters’ names have to do with nature and beautiful colors, love it that they’re fam names, too.
