History & Origin

Katelynn is a modern English variant of Caitlin (Irish) or Katelyn, which derive from the Greek Aikaterine (Katherine), meaning pure or unsullied. Katherine spread through Europe via Saint Catherine of Alexandria.

Katelynn belongs to the large family of Kate/Katelyn/Caitlin variants popular in English-speaking countries since the 1980s. The double-nn ending is a modern elaboration for visual distinction.
