I really like
Elena but there are so many pronunciations of it! I would automatically pronounce it ehl-EE-na, my landlord's name is spelled
Elena and pronounced EHL-e-na, and my personal favourite pronunciation is eh-LAY-na.
So I would go for
Elaina to make the pronunciation clear but then it looks too much like
Eliana... Therefore,
Elaina /
Alaina /
Elena /
Olena are always mns in my combos these days.
