What do you think of
Sunniva?
And how do you pronounce it? I've seen people say that they pronounce the first syllable both as in "sun" and as in "soon." I pronounce it somewhere in between, with the vowel sound sounding like the one in the middle of "could." Do you think that this pronounciation is too unintuitive? I think that that's the proper (or as close as I can get to proper) pronounciation, but I'm not entirely certain.
Any combo suggestions? I'm having a lot of trouble with middle names for this one.
