Middle name for Gloria

St

We know we want Baby G to be Gloria, after my grandmother. The middle name is harder... leaning toward Gloria Gabrielle right now, and have considered Noelle or Rose as well.

Gloria doesn’t lend itself to nicknames, so we’re looking for something traditional that will be a good alternative if she chooses to go by it. Bonus for French and or flower names.

Last name is Robertson, siblings are John Frederick and Madeleine Lorraine.
