Do these names fit well together

[Donnaj28]

June, Lilia, Claire, Milo & Oliver

Yes very nice

They are all nice names. They all are different enough from eachother and there are a range of lengths/syllables etc, so they go together nicely.

That being said, I would guess June and Claire to be a person born in the 80s or before, rather than names being used as baby names in 2020. I'm in my 20's and have never met a Claire or a June near my age group or younger (and I work facing all ages). But that's just my opinion, and I'm not sure what your context is / whether or not these are potential baby names. Besides, any context wouldn't stop the 5 of them from being nice names that all go together. 🙂

I think they are all nice names

Claire is v 60s, 70s, 80s, so likely to stay out of fashion for a while. But it is classic so it doesn’t sound dated.

June is 30s, 40s, 50s. Not being revived yet but could be soon - similar to May and Juno which are both popular now. Some people will feel it’s an old lady name.

Oliver has been in steady use since the 60s, popular now, so quite classic

Milo fashionable now and popular. I’d say it’s a cool name right now.

Lilia less common but feels like an attempt to find something different to the overused Lily?
