Evelynn is beautiful.. I’m a big fan of E names (mostly because my full name is Elizabeth)😊

Here are some unique E names I found:
Emilia
Estelle
Eilinora
Everlee

I was the same way...but Husband only liked "Lincoln" so I made it Lyncoln and it's a great unique name!

Jada

My first son was supposed to be Evelynn Marie if he was a girl. I also like the name Mackenzie Elizabeth. This baby if he ends up being a girl it will be Gabrielle Clara.

Greek mythology names are also pretty cool.

You could also go with old-fashioned classic names like:
Hazel
Ethel
Mavis (my grandma’s name ❤️)
Betty
Margaret
Margeurite
Diana
Ruby
Muriel (my auntie’s name ❤️)
Iris
Astrid

These are names you don’t really here much, so maybe that would be unique enough for your SO?
