Name help...sibling name that sits well with Alba

[gemlouise123]

Hi all, I’d love your help with siblings names (sex unknown) for our baby. DD is Alba, we like simple but strong names.
I’m just having trouble finding anything that I love as much as I love Alba. We like Nova, Rowan and India and for boys we like Sebastian.

Astrid
Delphine
Celeste
Estelle
Athena

Enzo
Flynn
Cassius
Oberon
Magnus
Rocco
Lennox

I like Nova. Nice and short, like Alba

Renz for a boy? Not my personal choice but I know of an Alba & Renz.

Lua, Indie, Marnie, Noa

Luca, Jaco, Trent, Otis

Cymru?

How about Axel or Otto for boys names?
Girls - Anouk?

I don’t think of Sebastian as either simple or strong, but I guess that’s only my view!

Zoe for a girl. Why not Rowan for a boy?
