The name Kaitlyn is a girl's name of Irish origin meaning "pure". Kaitlyn is ranked #326 on our popularity charts and is often added to lists like If You Like Kaitlyn, You Might Love... and discussed in our forums with posts like "Sibsets you know".
From the experts:
A huge name over the past few decades, Kaitlyn's just started dropping down the charts while others -- the original Caitlin and Kaitlin, for instance -- have been moving down for some time. No matter how you spell it, Kaitlyn, now still at Number 197 and given to more than 1500 girls last year, has at this point been considerably overused and can no longer be seen as stylish. It's especially popular in Canada.
