Aydan

Aydan () is a Guanche and Irish male name or Turkish and Azerbaijani feminine given name and surname. 
The Irish male name is derived from the name "Aodhán", which is a pet form of "Aodh". The personal name "Aodh" means "fiery" and/or "bringer of fire" and was the name of a Celtic sun god (see Aed).
Formerly common only in Ireland and Scotland, the name and its variants have become popular in England, the United States, and Canada. "Aidan" has been the 57th most popular name in the United States since the start of the year 2000, bestowed on over 62,000 boys, while "Aiden" ranking 66th, has been used on over 51,000 boys. Other variants are a bit less popular, such as "Hayden" 88th, "Ayden" 189th, "Aden" 333rd, "Aydan" 808th, and "Aydin" 960th, according to the United States Social Security Database. "Aidan/Aiden" was the most popular boys' name in Canada in 2007.
The Guanche male name can be roughly translated as "he who lives underwater".
The Turkish and Azerbaijani feminine given name literally means "from the moon" ("ay": moon, and -dan is a suffix meaning "from"). Figuratively, it means made of the moon or the one that comes from the moon.
Aydan is also a Turkish geographical name, notable the modern town in Anatolia (Asian Turkey), near the Ancient Roman city and bishopric and present Latin Catholic titular see of Attanus
