Clare, rather than
Claire; but I'm not in a region where French is spoken. I like
Clara with the
German pronunciation; I find it alarmingly comical when Americans rhyme it with
Sarah.
Clare,
Claire and
Clara have never been really well used in South
Africa.
I'm not sure if you are thinking about a possible combo or a possible sibset: either way, I'd use
Elinor (or
Eleanor) and/or
Annabel.
