Twin girl names: Charlotte and…??

I’m helping a friend come up with name options for her identical twin girls, and we thought we’d crowdsource some ideas. She and her husband are pretty set on Charlotte for one of the twins. We’d love to hear your name ideas for the other!

More context: They live in the US; she’s Jewish and of Danish/Dutch descent; he’s South African (they’re both white). Their older child is named Logan. She prefers softer, feminine names like Willa and Lara; he prefers more androgynous names like Harper and Parker.
