I've been really liking this name as well (though I've been leaning more toward it being for a boy, myself, mostly because I prefer
Temperance for a girl). Nonetheless, I really do like it for a girl as well.
Tempest Eliza Miriam is a lovely combo! I think the more traditional names,
Eliza and
Miriam, complement
Tempest very well. Nice combo, and nice names all-around.
