Dull
A nickname surname that likely began as a description of someone considered dull, heavy, or slow-witted.
The #6,961 most common surname in the United States (2010 Census) — about 1 in every 64,082 Americans shares it.
Etymology
This surname is most likely from Middle English dull, meaning slow, heavy, blunt, or lacking brightness. As a family name, it probably began as a nickname for someone thought to have a quiet, sluggish, or unremarkable manner. The word itself is old Germanic in origin and has long carried senses like dim, stupid, or lifeless in English.
History
The name is found in English records as a straightforward nickname-type surname, though the surviving excerpt evidence does not give a single secure first bearer or location. Because dull was a common descriptive word, the surname may have arisen independently in more than one place. Modern bearers are concentrated in the English-speaking world, especially the United States.
