One I met recently and thought, wow great name was little Milla. She was Millicent Theadora Amelie which I think are my current top 3! (But Thea not Theadora for everyday). Just a longshot incase you share my taste!
Other lovely ones you may not have thought of/bit more unusual that I've heard on here or in RL are Orla, Ottilie, Evangeline, Emmelina, Saskia, Coralie, Clemmentine (Clemmy), Allegra, Arabella,
Names I like not mentioned: Lydia Darcy Matilda, Tilly, Tildy, Tilda, Matilde Poppy Sophia, Sophie, Sofie, Sofia Daisy Fenella Holly, Hollie Kyra, Kivanna Lottie, Libby Lucinda, Lucie, Lucy Callie Bella Megan Maisie Victoria Alice- wait and see what the Royal baby is called first though! Millie, Mollie
