This character name from the Throne of Glass series by Sarah J. Maas has an ancient appeal, even though it seems to be a modern coinage. It may have been inspired by similar sounding names, like the Turkish Aylin ("of the moon") or the Irish Eileen, a form of Helen or Aveline.

A fairly common name in many Slavic countries, especially Russia – perhaps in part because it sounds close to the name of the country, although the two words are unrelated etymologically. The name Ruslan was used by Russian poet Alexander Pushkin for the hero of his epic poem Ruslan and Ludmila, based on Russian and Tatar folktales about the hero Yeruslan Lazarevich. Yeruslan or Uruslan is a Tatar name likely deriving from Turkic arslan "lion".

Turquoise is similar in hue to Aqua, which is one of the cool new color names on the palette. Other blue-hued options: Cerulean, Cyan, Indigo, or Blue itself.

Top 10 in Turkey and Top 500 in the Netherlands (which has a high Turkish population), this sleek and pretty name is virtually unknown elsewhere.
