Beatrice - Beautiful
Bryony - lovely and a bit on the hippy/ arty side too
Constance - beautiful but I really dislike Connie as a nn
Cordelia - lovely, makes me think Brideshead Revisited
Effie - sounds like a curse under the breath, and also a milkmaid's name
Eleni - lovely, very Greek
Elodie - sounds truncated, as if it should be Melody
Elsa - lovely, Germanic, would be very nice with Magnus
Emmi - too nicknamey. Would you use Emma or Emmeline on the BC?
Evangeline - too much. Angeline is nice. Evangeline is like a conglomeration of two long names.
Genevieve - nice but a bit frilly
Leonie - lovely and unusual
Livia - lovely, less popular than Olivia
Magda - beautiful, Germanic, and would be very nice with Magnus
Marlena - lovely if pronounced the German way and even spelled Marlene, also great with Magnus
Natalie - nice but I prefer Natalia
Ronja - not sure; too like naming a girl after a male relative called Ron
Thea - nice but a bit wispy
Vivienne - very nice
I like Elsa, Magda, Marlena/ Marlene and Leonie, Beatrice, Bryony, Constance, Vivienne and Cordelia.
