Help me spell my baby's name!

Shelbi
We had a blast at our gender reveal party tonight! We are having a girl! So here is my delimma.... 
I want to name her after Marlena from Water for Elephants (it's my favorite movie and my mom named me after her favorite movie). But my husband doesn't like the name, so we compromised on taking the "mar" off. (Pronounced like Elena, without the E). How have you seen this spelled? I want to spell it Leighna, but I know some people see "Leigh" and see "lee." Her name isn't "leeeee-na" it's "laaaaa-na" lol
How should we spell it? Thanks y'all!
