Christopher nn Kit! Yes! I've not met a baby Christopher, or even a child Christopher. Same about Thomas. MN adores it but not met any since I was a child. Tristan is another one I only hear on MN and have never met.
I am not a fan of Ottilie either, and am always surprised when MNers suggest it with such enthusiasm as to me it seems to break a lot of MN rules (eg it's not a classic and is never pronounced how it should be if you're going to stick to the original European pronunciation which is sort of like - Ott-eel-yuh. I personally don't agree that it's wrong to anglicise names, but MNers often kick off about anyone who wants to pronounce Xavier or Genevieve in the normal British way, so why is it okay to pronounce Ottilie as Otterly?)
Clementine seems OTT to me too, although I do love the sound, to me it seems just too MUCH to be usable, but yeah I agree this is another which everyone loves.
I didn't used to like Anna, Alice or Lucy as I felt they were dated and dull but MNers love them so much that they've really grown on me, Lucy in particular! But I was very surprised initially to see people raving about how classic and pretty they were, as i'd never really thought of them like that. The only people I know with any of these 3 names are people I went to school with, but no babies.
I do know a little Margot and Maeve though!
Recently Gabriel seems to be being suggested a lot, but it seems to be a very recent favourite.
