Names with O in them

We need a unique name that either starts with an O or has an O in it. We don’t know the gender yet, so we need ideas for a boy & a girl.

Our first daughter is Gwendolyn

For our (possibly) second we liked Olivia & Nora, but they’re too common. But we love how they both have an O like Gwendolyn

For a boy, we like Nolan, but we aren’t sure because they’d both end in “n” which is kinda rhymey.

Please drop ideas!!!
