Kathaleen

Meaning & origin

Kathaleen is a spelling variant of Kathleen that saw its brief peak usage in the United States mid-century. The name was first recorded in 1902 but enjoyed its greatest frequency in 1950, the peak year, when it reached its highest rank (though not in the top 1000). Since then, its trajectory has been stable but very low, with intermittent usage in the decades following. Unlike the more common Kathleen, which ranked among the top 100 from the 1930s through the 1960s, Kathaleen never achieved widespread popularity. The name was primarily concentrated in states with large Irish-American populations, though it never registered enough births to appear in top state lists. Overall, Kathaleen remains a rare choice, appealing to parents seeking a distinctively-spelled version of a classic Irish name.

Kathaleen is a variant spelling of Kathleen, the Anglicized form of the Irish name Caitlín, itself derived from the French Catherine. Catherine ultimately comes from the Greek Aikaterinē, whose meaning is uncertain but traditionally linked to katharos meaning 'pure'. The name was introduced to Ireland through Norman influence and became widely used there. The spelling Kathaleen emerged in the United States in the early 20th century, reflecting a phonetic rendering.
