Aideen is an uncommon Irish female given name, derived from the Irish word 'Aithin', which means 'little fire'. It is a variant spelling of Aidin, another form of the same name. The name Aideen was popularized in English literature by William Carleton's novel 'The Blackthorn', published in 1853. It has since gained some recognition as an Irish name but remains relatively rare.
"The name Aideen has seen a steady decline in popularity over the years, with only seven births recorded in 2022 compared to its peak of 13 in 2011."
