I like:
Harriet,
Isadora,
Rowena and
Winifred, and
Henry and maybe
Sid (if only the French for Aids wasn't SIDA which is all I can think of when I hear
Sid now, and I actually like it as a nickname for
Isidore /
Isidora and by itself it's a bit defiant, a bit punk, a bit rebellious in feel).
Rose as a fn is nice too, in a very plain, traditional, simple, down-to-earth way.
I'd like
Cressida, if my brain didn't focus so much on the 'cress' aspect.
