Etymology
Sheldon is an English habitational surname taken from places called Sheldon, especially in Warwickshire, Derbyshire, and Devon. The name is usually explained from Old English elements meaning a shelf, ledge, or crag plus dūn, “hill,” so the place-name sense is roughly “shelf hill” or “ledge hill.” Some 19th-century writers also glossed it more loosely as a spring-and-valley name, but the Old English “shelf hill” derivation is the stronger and more widely accepted explanation in the historical sources here.
History
The surname appears in medieval records from the Midlands and later spreads into other parts of England. Warwickshire Sheldon is especially important because it was described as an early seat of the family. The name later traveled with English migrants to North America and elsewhere, and it remains a fairly well-known but not overly common surname.
