Middle Names For My Girls

I’m looking for middle names for Romilly, and Briony.

Brother is Tolliver Invictus. Sister is *Delaney Meliora.

Thanks in advance.

*Update: This is only planning, so none of these children exist yet, and everything is getting moved around a lot. I’m removing the name Delaney from this set. It’s nothing against the name, it’s a very personal name for me, and I love it, but I feel like it’s not quite fit for the rest of the set. That being said, the middle name Meliora is staying, but it will be moved to the middle name spot for either Romilly or Briony.

What I need now, is your vote on which one it sounds better with, and another middle name, potentially inspired by the name Delaney, for the other girl.

Thanks in advance (again).
