Black-haired or dark-haired
Daegan is a modern spelling variant of the Irish name DeaglΓ‘n (Declan). While its exact etymology is debated, it is most commonly associated with the Gaelic elements meaning 'full of goodness' or 'black-haired'. It has gained some traction in North America as a creative alternative to more common 'D' names.
