Delaware is the name of a U.S. state as well as several other places in the U.S. as well as the name of a Native American tribe (also known as the Lenape). The name comes from Thomas West, the 3rd Baron of De La Warr. The name De La Warr is an English surname (of Norman origin), made up of de la werre (werre being an Old English word meaning “war”) or de la guerre (guerre being the French word for “war” as well), which may have originated as nickname for a belligerent person or someone who was a soldier.
It’s also possible that it may have originated as a locational name for someone who lived near a weir.
