I'm not sure it goes 100% with your other DC's names but I don't know if that matters in the long run if you love the name.
My friend has two children with quite modern/colloquial names - her third is called something quite classical and my first thought was
.
She's 5 now and she is who she is and the combo of names is totally irrelevant.
One of my closest friends is Natalie so I'm a bit biased!
