Need Help Finishing Sib Set

writting a short story about a family, need names for siblings. mother is [name]Katherine[/name] [name]Grace[/name] and father is [name]Thomas[/name] [name]James[/name]. names i have so far for sibs are:
[name]Malcolm[/name] [name]Thomas[/name]
[name]Camilla[/name] (need mn)
[name]Emmeline[/name] [name]Claire[/name]
[name]Lucas[/name] [name]William[/name]
[name]Bryony[/name] [name]Grace[/name]
need one more girls name
surname is [name]Royce[/name]. i appeciate any thoughts on my names so far. thanks so much

If [name]Camilla[/name] is the oldest girl, I’d use [name]Grace[/name] or [name]Gracie[/name] as her mn instead of using it for [name]Bryony[/name]…[name]Camilla[/name] [name]Grace[/name] is so lovely too, [name]IMO[/name]…
I think [name]Bryony[/name] [name]Kate[/name] / [name]Bryony[/name] [name]Katherine[/name] works well.
Perhaps [name]Margot[/name] [name]Jaime[/name] (to honor Dad’s mn) for the youngest girl?
