Aiden is the Anglicized form of the Old Irish name Áedán, which is derived from the Old Irish element Áed, meaning "fire." As a baby name, it's often translated to "little fire." It's a name given to the sons of legendary singer Rod Stewart and actress Jennifer Love Hewitt, though she and her husband Brian Hallisay spelled it Aidan. Aiden has been a top 100 baby boy's name since 2003, but Aidan, Aden and Ayden are also popular today.
