Hard Time Picking a Girl Name

We could pick another boy name in five minutes, but we cannot find the girl name. I’ve searched so many lists and nothing feels quite right.

One of our main criteria is choosing a name that will grow well from child to adult. For example, we like Callie, but we worry it might feel less formal if she ever wants something more professional as an adult.

One of us leans more traditionally feminine, while the other prefers more gender-neutral names. My spouse likes the name Ryan for a girl, but I can’t wrap my head around it when written out, so it didn’t make the cut.

Names we’ve liked but aren’t sold on for various reasons:

Mila

Callie

Olivia

Piper

Spencer

Her brother is named Rhys, and our last name starts with a K sound and is one syllable.

We’d love suggestions that feel wearable at every age and maybe strike a balance between feminine and neutral. Open to any ideas!
