Caitlyn is a unique and modern female given name of Irish origin. It means 'pure' or 'virginal,' derived from the ancient Gaelic word 'caitlin.' The name gained significant popularity in the 21st century, particularly after the announcement by Caitlyn Jenner in 2015 that she identifies as a woman. This event brought the name into the public eye and led to an increase in its usage.
"Catelyn experienced a surge in popularity between 1998 and 2002, with the highest number of births occurring in 2002 at 13. However, it has since seen a decline, with only 5 births recorded each year from 2003 to 2005, and again in 2008."
