Our toddler is [name]Camille[/name] and we are expecting twin girls this winter. We are set on [name]Penelope[/name] for one of them, but having a difficult time with the other one. Any ideas?
I love both [name]Penelope[/name] and [name]Camille[/name]! Gorgeous choices!!!
[name]How[/name] about:
[name]Clementine[/name]
[name]Imogen[/name]
[name]Evangeline[/name]
[name]Cecilia[/name]
[name]Wren[/name] (being a bird name, [name]Penelope[/name] means “duck”)
[name]Aria[/name]
[name]Adeline[/name]
[name]Matilda[/name]
[name]Scarlett[/name]
[name]Eliza[/name]
[name]Adriana[/name]
[name]Allegra[/name]
[name]Paloma[/name]
[name]Georgia[/name]
[name]Melina[/name]
[name]Fiona[/name]
[name]Carina[/name] (maybe too close to [name]Camille[/name])
[name]Cordelia[/name]
[name]Rosalind[/name]
[name]Augustine[/name]
[name]Eleanora[/name]
[name]Lilia[/name]
Oh, I don’t know if I should go Greek like [name]Penelope[/name] or French like [name]Camille[/name]!
[name]Daphne[/name]
[name]Hermione[/name]
[name]Beatrice[/name]
[name]Brigitte[/name]
[name]Francine[/name]
[name]Genevieve[/name]
[name]Giselle[/name]
[name]Marguerite[/name]
[name]Mirabelle[/name]
[name]Nicolette[/name]
[name]Simone[/name]
I love both [name]Penelope[/name] and [name]Camille[/name]! They’re both from different origins (very different 
but somehow they seem to fit. So another name to fit this duo might be (and I apologize in advance for repeats as I didn’t read over the previous posters before):
[name]Cecilia[/name] nn Cece/[name]Lia[/name] (or just [name]Cecilia[/name])
[name]Harriet[/name]- [name]Hattie[/name]
[name]Juliet[/name]
[name]Alexandra[/name]- [name]Alex[/name]/[name]Alexa[/name]/[name]Xandra[/name]
[name]Daphne[/name]
[name]Genevieve[/name]- [name]Vivi[/name], [name]Gen[/name]
[name]Sylvia[/name]/e
[name]Emmeline[/name]- [name]Emme[/name]/[name]Emmy[/name]
[name]Rosaline[/name] (or any [name]Rose[/name] names)- [name]Rosie[/name]
[name]Kathleen[/name]- [name]Kate[/name]/[name]Katie[/name]
[name]Clementine[/name]- [name]Emme[/name]
[name]Giselle[/name]
[name]Angelina[/name]- [name]Angie[/name]/[name]Lina[/name]
[name]Estelle[/name]
[name]Mallory[/name]
Good luck :)!!
I love [name]Helena[/name] and [name]Daphne[/name] for twins, and they would go great with your [name]Penelope[/name] and [name]Camille[/name].
Some more suggestions:
[name]Helena[/name]
[name]Daphne[/name]
[name]Adeline[/name]
[name]Adelaide[/name]
[name]Seraphine[/name]—or is this too much?
[name]Anastasia[/name]
[name]Tabitha[/name]
[name]Meredith[/name]
[name]Lorraine[/name]
[name]Annabel[/name]
[name]Madeleine[/name]
[name]Josephine[/name]
[name]Vivienne[/name]
[name]Gwyneth[/name]
[name]Dorothy[/name]
[name]Amelia[/name]
[name]Hazel[/name]
[name]Millicent[/name]—love this, but it might be too much [name]Milly[/name]
[name]Charlotte[/name] and [name]Priscilla[/name]—so you’ll have 2 Cs and 2 Ps
[name]Matilda[/name]
[name]Louise[/name] or [name]Louisa[/name]
[name]Elaine[/name]
[name]Rosalind[/name]
You have a baby [name]Camille[/name]? I think it’s such a beautiful name! 
I love [name]Penelope[/name], too!
I couldn’t remember all of the previous suggestions, so I’m really sorry about the repeats that will surely follow:
[name]Penelope[/name] and:
[name]Aurelia[/name]
[name]Adelaide[/name]
[name]Adeline[/name]
[name]Annabelle[/name] (kind of close to [name]Camille[/name]'s ending, though)
[name]Anneliese[/name]
[name]Amandine[/name]
[name]Daphne[/name] (same ending sound as [name]Penelope[/name], though)
[name]Dahlia[/name] (more in line with [name]Camille[/name])
[name]Evangeline[/name]
[name]Eleanora[/name]
[name]Emmeline[/name]
[name]Genevieve[/name] (nn [name]Evie[/name])
[name]Helena[/name]
[name]Iris[/name]
[name]Imogen[/name] (then again, it’s a bit clunky next to [name]Camille[/name])
[name]Josephine[/name]
Juilet/[name]Juliette[/name]
[name]Lydia[/name]
[name]Margot[/name]
[name]Rose[/name]
[name]Violet[/name]
[name]Vivienne[/name]/[name]Vivian[/name]
Best wishes to you!
I love both [name]Camille[/name] and [name]Penelope[/name]! I have to admit I never would have paired them for sisters but they do go and create such a lovely and unexpected sibset! So for [name]Penelope[/name]'s twin, I think the name has to be beautiful, strong and uncommon but classic. [name]How[/name] about:
[name]Delphine[/name]
[name]Aurora[/name]
[name]Gwendolyn[/name] (I have a certain bias, but I do think it fits the criteria
[name]Melisande[/name]
[name]Miranda[/name]
[name]Leonore[/name]/[name]Leonora[/name]/[name]Leora[/name]
[name]Lorelei[/name] - both [name]Penelope[/name] and [name]Lorelei[/name] have mythological background
[name]Cassia[/name] - but I was trying to avoid C and P
[name]Dorothea[/name]
[name]Sibylla[/name] - sibyls are mythical prophets
[name]Antonia[/name]
[name]Daphne[/name]
Good luck!
[name]Penelope[/name] and [name]Camille[/name] are so pretty!
[name]Linnea[/name]
[name]Calista[/name]
[name]Josephine[/name]
[name]Amelie[/name]
[name]Helena[/name]
[name]Claudia[/name]
[name]Beatrice[/name]
[name]Miriam[/name]
[name]Louisa[/name]
[name]Jessamine[/name]
[name]Charlotte[/name]
[name]Eloise[/name]
[name]Elodie[/name]
[name]Matilda[/name]
[name]Estelle[/name]
[name]Althea[/name]
[name]Theodora[/name]
[name]Cecilia[/name]
[name]Annabel[/name]
[name]Frances[/name]
There are lots of great suggestions here but my favorites to pair with [name]Penelope[/name] are…
[name]Rosalind[/name]
[name]Simone[/name]
[name]Margot[/name]
[name]Helena[/name]
Good luck!
