The surname Graham is an Anglo-French form of the name of the town of Grantham, in Lincolnshire, England.
[2] The settlement is recorded in the 11th century Domesday Book variously as Grantham, Grandham, Granham and Graham.
This place name is thought to be derived from the Old English elements grand, possibly meaning "gravel", and ham, meaning "hamlet" the English word given to small settlements of smaller size than villages.
Alternatively, possibly from Old English græghama "grey-coated one" (ie, wolf).
The forename Graham is considered to be an English and Scottish given name.
