Hello,
We now know our fourth is a little girl. :)
After Josephine, Iris and Theodore struggling to decide on a name. 
I’d like something timeless and elegant like I feel Josephine and Iris are. Classic but not too popular.
I like the following:
Florence - too popular?
Beatrice - too popular?
Eleanor - but rhymes too much with Theodore?
Alice - too close to Iris
Rose - a 2nd flower, really?
Harriet
Georgiana
Phoebe
Arabella
Elinor
Charlotte - too popular?
Ottilie
Welcoming other suggestions and feedback.
Thank you!!
