Aidyen, pronounced /ei-dee-en/, is of Scottish origin and means 'little fire'. It's derived from the Scottish Gaelic Aodhán, which is a diminutive form of Aod, meaning 'fire'. Aidyen is quite rare and unique, with its usage most prevalent in Scotland. It gained some popularity in the late 20th century but remains relatively uncommon today.
"Aidyen saw exactly five newborns in 2009, with the overall tally remaining at five."
