Cordelia Hazel June

why/why not?

No. It's a nice name, just nms.

I like Cordelia Hazel, but not June.
It just doesn't flow that well imo.

I know you like the two-middle-name thing, which is cool, but with Cordelia being 4 syllables, that all makes for a long name. Which is fine, and you're probably not going to call her all that all the time, I imagine. Some people may suggest a one syllable middle name if you plan to call her by her whole name often. If none if this is an issue, though, go for it! All those names are fine, and if you love it and it suits her and the situation, that's wonderful! Best wishes.

i doesnt run well with me

I love it it! So classic and gorgeous! Hazel is one of my favourite names ever and I love Cordelia anyway, June flows with it all so nicely!

good luck!
