Sibling name for…

On behalf of a friend:

“We are expecting a baby girl in April and cannot choose her name. We already have 3 children; Harry (6), Jack (4) & Isla (2). DH and I like that “cheeky British” vibe, probably because we are British and living in Britain 😂.

Names we love but can’t use would be: Charlotte, Grace, Isabelle, Zara, Mia, Millie, Emily, Anna & Ava. Any help is much appreciated as I’m completely drawing a blank, as is DH. The kids meanwhile keep throwing out Paw Patrol characters as name suggestions 🙄😂.”

ETA: Stated August instead of April as due date/month 🙈
