U.S. state, river, and native tribe, all named for the bay, which was named for Baron (commonly "Lord") De la Warr (Thomas West, 1577-1618), first English colonial governor of Virginia. The family name is attested from 1201, from Delaware in Brasted, Kent, which is probably ultimately from de la werre "of the war" (a warrior), from Old French werre/guerre "war" (see war (n.)). Related: Delawarean.
