I love
Matilda, mainly because of the
Roald Dahl book. I think the name is quite popular in Australia (possibly because of the song 'Waltzing
Matilda') but I don't think I've met anyone with the name here in New Zealand. I like the
Matilda spelling best. My biggest (and only, really) problem with the name is that I dislike all of the possible nicknames, so I wouldn't use it as a FN. If I had to choose one I'd probably go with
Tilda.
My favourite by far of your combos is
Matilda Clare, because it used to be one of mine before I inverted it because of the nn thing (
Claire Matilda is my #1 girls name).
The others are a bit old-fashioned.
Matilda already has quite a bit of that, and putting it with
Winifred and
Pearl does nothing to freshen it up.
