Is this a good name for my sibset

[Traditionalwife]

My current children are Caroline Adele, Annabel Frances and Penelope Louise I was thinking Oliver or Eloise not sure about the middle names yet.

Love both Oliver and Eloise and think they go great with your other siblings

"sibset" isn't a word I've come across before but I feel it could be applied to the thinking of a family I knew who called their children Penelope, Kenneth and Dennis.

Or as they used to say (because it was, apparently, cute): Penny, Kenny and Denny.

Kenny eventually rebelled because he thought it sounded stupid* and took to calling himself "Kenny-second name" (eg Kenny-Tim; changing names on the tiny off-chance they're reading this).

Anyway. Not helping with your question.

I like Miranda or Huw.

*Rightly so, imo.
