Can't say I like any of them.
The only -olly name I like - and I like it very much indeed - is
Polly, perhaps because it's a family name. I've got a step-niece named
Holly who's a pleasant kid, but my opinion of her name is unchanged. I don't think she was a
Christmas baby: her father is profoundly deaf, with very poor speech, and his children have names that he can cope with.
Noelle annoys me. South Africans have always been bad at French, though it's improving now, and when
Noelle was in use about, I suppose, 40+ years ago the best attempts tended to be nuhWELL, which isn't attractive. A friend of mine's brother married a woman named
Noel, which has made me believe that it can work for both, but perhaps it can't really. I'd only use
Noel for a girl, and only as a mn, and then only if I suddenly became (a)
Christian and (b) pregnant!
Natalia goes on for too long.
Natalie is bland, a sweet little nothing of a name, but at least it isn't tedious and sounds better.
In general, I'd try to avoid
Christmas names,
Easter names, seasonal and geographical and slogan names.
Once there was a High Court judge in the UK with the resounding name of
Christmas Humphreys; the cherry on the top was that he was a Buddhist.
