Jesse is very southern american ("texas sounding") and western souding to me. I don't really like it, maybe because it's so close to
Jessie. I prefer
Jesse as a nickname, maybe for
Jeremias? I don't like
Iris either. It's too cute and has a bad sound.
Of your suggestions
Iris Amelia and
Jesse Micaiah is the best (even though I like
Daniel more..)
