Katelyn

Add "Kate" to "lyn," and you get Katelyn, another modern variation of the classic "Caitlin," a pretty Irish name that comes from the Celtic "Catherine," which itself is from the Greek "Aikaterine." However you choose to spell it—other variants include Katelynn, Kaitlynn and Kaitlen—the name's meaning translates to "pure." No surprise then that St. Caitlin was associated with courage and purity. While Kaitlyn wins the top spot among spelling preferences, Katelyn isn't too far behind.
