Suggestions for sister to Gabrielle Fay
Avara Juliet (meaning the youngest)
Clementina Noelle (meaning merciful)
Michaela Jane (I like Michaela but only spelt like this but some may find it a little dated.)
Gabrielle Faye and...
Elodie Arcadia (perhaps this feels 'fresher'?)
Dominique Maeve (love this!)
Vivienne Arcadia (love this with Gabrielle)
Aimee Juniper (Aimee means 'beloved')
Charlotte Maeve (very similar 'feel' to Gabrielle Faye IMO - I think they're gorgeous together!)
Ahh! Sorry I posted so many. Hope you find some inspiration here!
