Sibling for Athena

[Redcart21]

We don’t know the sex yet but looking for suggestions for both. DD1 is Athena and we want something which is in the same vein (no matchy names to mythology though as think it’s too much). DH and I have a mix of ancestory so name not limited to any cultures.
We want something fun, cool, easily pronounced. Doesn’t have to be a rare name, but we don’t want anything super popular like Emily, Ava etc.
My fave is Raphael so far, DH likes Sienna

Sophia

Rafe I think is Ray-f but nick name raffy is cool

Saskia
Romilly
Daphne

Luca
Otto
Otis

Hero

Rafe is pronounced 'Raif', but Rafferty is a good name to be shortened to Raffy...

Rafe is rhymes with safe

I've got a real thing for the name Pamela, I'm sure it's due a resurgence and would be really cool.

Ianthe; for a girl goes well with Athena

Persephone also

For a boy; Argo or Calix.

Personally I wouldn't worry about two names linked by an ancient culture. You should choose what you love. Have fun choosing

Iona

Cassius
