I am not a fan of
Gabrielle. I just don't find the whole "Gab" part attractive and I dislike the nn
Gabby very much.
However, I do love
Elle, which you could still use the nn
Ellie for.
Elle can very much stand very nicely on it's own. In fact, I really like the sound of
Elle Petersen. Even, your Earlier suggestion of
Elise could have the nn
Elle.
No,
Elle is not my real name but I wouldn't mind it all if it was. It's not popular, it's femimine but not frilly, and I just love the fact that it's French.
I hope I have been of help in some way.
For further assistance I came up with some middle names for the gorgeous
Elle:
Elle Katharine Petersen
Elle Antonia Petersen
Elle Julia Petersen
Elle Juliet Petersen
Elle Madeline Petersen
Elle Matilda Petersen
Elle Natalia Petersen
Elle Natalie Petersen
Elle Ophelia Petersen
Elle Suzanne Petersen
Elle Sofia Petersen - my favorite.
Elle Frances Petersen
Elle Francesca Petersen
Elle Amelia Petersen
Elle Genevieve Petersen
Elle Verity Petersen
