Etymology
Caitlin is a feminine given name of Irish origin. Historically, the Irish name Caitlín was anglicized as Cathleen or Kathleen. In the 1970s, however, non-Irish speakers began pronouncing the name according to English spelling rules as KAYT-lin, which led to many variations in spelling such as Caitlin, Ceitlin, Catelynn, Caitlyn, Katlyn, Kaitlin, Kaitlyn, Kaitlyne, Katelyn and Katelynn.
