I adore
Elena (pronounced eh-LAY-nuh). I started liking it first because it was the MN of a dear family member (Auntie
Bea who's full name was
Beatrice Elena), and as her mother's FN was
Lena I always pronounced it eh-LEE-nuh or ee-LEE-nuh and though I thought that was cute it wasn't until I discovered that
Elena could be pronounced eh-LAY-nuh that I started to love it! :)
Elena is a bit popular, especially in Hispanic cultures, though it's not as popular as
Ella has been. I agree that
Elena and
Ella are too similar, add to that
Elliott and then the other E names it would really be confusing. :(
Ileana is a lovely alternative though I prefer the Iliana spelling that I've seen various places.
Ayla is also sweet but doesn't quite have the same feel as
Elena. There's also several names that have the same sound such as
Helena (which I pronounce he-LAY-nuh),
Olena (which I guess would be oh-LAY-nuh), or
Yelena (which I'd pronounce rather the same yeh-LAY-nuh).
There's also many names ending in
Lena (LAY-nuh, or LEE-nuh if you prefer) such as
Marlena (mar-LAY-nuh),
Shelena (shuh-LAY-nuh or shee-Lay-nuh), or
Magdalena too! :)
