Merryn is a modern English name likely derived from the Cornish name Merryn, itself possibly a variant of Merryn (from the Welsh Meryn, meaning 'joyful' or 'light-hearted'), or a feminization of Merlin. It may also be a respelling of the Irish name Meara or a combination of Mary and Lyn. The name gained some usage in the early 2000s but remains rare.
