History of Manchester
According to Oxford University Press, Manchester derived its name from Mamucium, the Roman name for the 1st century-settlement and fort. Mamucium itself is a Latinised form of the Celtic meaning "breast-shaped hill".
Tottington, Greater Manchester
There is no mention of Tottington in the Domesday Book and little evidence of a settlement before the Norman conquest. The earliest extant record of Tottington is from 1212 when it was recorded as Totinton. Tottington's name is most likely derived from the Old English for the land or farmstead belonging to a man called Tota; or "tot" may be from an Old English word meaning "hilltop lookout point".
