Dermot is an appealing, relatively undiscovered Irish mythological hero's name long popular in the Old Country, and imported into the American consciousness by actor Dermot Mulroney. We see it in the next Celtic wave following Connor and Liam.
The name Dermot was borne by several early kings and a number of saints, as well as the legendary king of Tara. A further plus: The legendary Diarmaid (pronounced DEER-mit), a member of the band of Finn MacCool, had a mark on his face that caused women to fall instantly and madly in love with him.
Kermit the Frog owes his name to a regional variant of Dermot.
