Mcdermott Genealogy & Family Tree

McDermott is an Irish name from County Roscommon, Ireland, where the family descended from the kings of Connacht. It comes from the Gaelic Mac Diarmada which means "son of Dermot," a Celtic given name that means "free." The earliest known ancestor--Brian Mac Dermot--was recorded in 1592. The family motto is Honor probataque virtus which means "Honor and approved valor."

Other spellings include "McDermot," "MacDermot," "MacDermott," "MacDermitt," "McDermitt," and "MacDermit." Notable people with the surname include American actor Dylan McDermott (The Practice, The Perks of Being a Wallflower, Olympus Has Fallen), American actor Charlie McDermott (The Middle, Frozen River, Hot Tub Time Machine), and American Olympic athlete Don Joseph McDermott (speed skating). The first McDermott to come to America was Angus McDermott in Maryland in 1716.
