Alia is most classic and feminine form of Ali, one of the 99 attributes of Allah. The name is used by Christians, Muslims and Jews; the word Aliyah means to make a pilgrimage to Israel and the words in both languages mean sublime, lofty, or exalted. Alia is also the name of the heroine of Frank Herbert's science fiction classic Children of Dune
While Alia is the sleekest version of the name, both the most ancient and the most modern-feeling, its most famous relative in the U.S. today is the more complicated Aaliyah.
In this extended family of names, Aaliyah is the most popular, at Number 48, with Aliyah not far behind. Alia, at 612, and Aliya, at 788, are further down the list. All variants have been declining in popularity in the past few years.
