Astra is very pretty; I love how uncommon it is.
Celeste is very nice, especially as a middle name!
I like
Eliana a lot, but I'm not keen on the (potential) nickname "
Ellie".
Cassia is nice, but I much prefer
Cassandra over it.
Marcia is beautiful, when pronounced as "Mar-SEE-uh"
Madeleine is great, but I have vast preference for
Madelyn.
Amilia sounds nice, but I don't care for it.
Lucia is a gorgeous name.
I love the name
Evelina; it's very underrated, in my opinion!
