Actually, my favorite variant of
Isolde is
Eseld :-) I love all of variations, though. I don't think it's anything like the popularity surrounding
Isabella, which I think has more to do with the 'bella' and 'bel' rather than the 'Is' part of the name.
Anyway, my favorite
Eseld combos are
Eseld Amelia and
Eseld Camille. I've only just began thinking of combos for it though, so I haven't come up with much just yet. I'm remaining picky about it lol
