Manor
The toponym was originally simply "Clifton", meaning "tun on a cliff" in Old English. There is no documentation for the "Hampden" part of the name from before 1726.
In the Anglo-Saxon era Clifton belonged to the Bishop of Dorchester. After the Norman conquest of England William the Conqueror transferred the see to Lincoln, with its properties including Clifton.
