Keythorpe, in the Gartree Hundred of Leicestershire, is an Anglo-Scandinavian hybrid from the Old English male personal name Keyia or Keia and Old Norse þorp ‘a secondary settlement, a dependent outlying farmstead or hamlet’. It was a daughter settlement of Tugby, which it is now a joint parish with.
Alternatively, the first element could be the Old English male personal name Cœga, but this seems to be too early of a name to pair with þorp. The Old English element cœg ‘a stone’ has also been suggested; however, the drift ecology does not reflect this postulation.
