Crumpton
A locational surname meaning “from Crompton,” the Lancashire township name behind the family name.
The #6,765 most common surname in the United States (2010 Census) — about 1 in every 61,935 Americans shares it.
Etymology
Crumpton is generally explained as a surname formed from the place-name Crompton in Lancashire, rather than from the word "crump" itself. The placename is usually analyzed as an English habitational name, probably built from an Old English element meaning a bend, curve, or crooked feature, plus a topographic ending. The surname therefore most likely meant simply “someone who came from Crompton.”
History
19th-century surname writers explicitly link Crumpton to Crompton and note that it spread strongly through Lancashire. As with many English locational surnames, it later traveled well beyond its original county and became established in the United States. The spelling with -u- is a common surname variant of the place-based name.
