Does this sound smooth and meld together?
My top choice:
Leilani Mei Morse
Leilani Mae Morse
Leilani May Morse
Meaning:
Leilani - "Heavenly Flower" (Lei) flowers (lani) of the sky or heavens
Mei, May, Mae (Haven't decided which spelling) "beloved, bitter, drop of the sea, pearl", or "may" - symbolism of spring, growth, and renewal.
