I'm like you and tend to have more traditional/old fashion favorites.
But that being said,
Lyra is nice. Feminine and pretty, but not trying too hard to be different.
If it were me, I'd probably pair it with a more tradtitional middle name or perhaps a family name.
Lyra Jane,
Lyra Corinne or
Lyra Camille are the first few to come to mind.
For siblings, I like:
