Kathleen is a female given name, used in English- and Irish-language communities.
Sometimes spelled Cathleen, it is an Anglicized form of Caitlín, the Irish form of Cateline, which was the Old French form of Catherine.
[1][2] It ultimately derives from the Greek name Aikaterine, the meaning of which is highly debated (see Katherine).
Kathleen was the 8th most popular girls' name in Ireland in 1911,[3] but by 1965 it had sunk to number 18.
