Calla
Calla Celeste--This was the name we gave to my daughter who passed away. Calla is a type of flower (a lily to be exact) and Celeste means heavenly. It fit her perfect. It turned out to be a very beautiful name and we've never heard anything but compliments on it. Calla is simple and elegant and not too difficult to pronounce.
Calla is used as a name after the calla lily, a decorative flowering plant. Calla also may be inspired by the Greek kallos meaning "beauty," as found in names like Calista and Calantha.
