The English surname Dodd is one of the first Anglo-Saxon names recorded.
In the West of England, Dodd is understood to be of Ancient Welsh Celtic origin.
It may also have Germanic origins if found in the East of England, stemming from a description of something "round or plump" as a surname based on nicknames.
The surname Dodd may also be derived from the Old English word "dydrian", in East England which means deceiver or rascal, or from the word "dod", which means to make bare or to cut off.
[1] Through migration, the surname Dodd has become common throughout the British Isles and the broader English-speaking world.
