may I leave you, what I have found out from different publications on the name 'Cleator'.

The name Cleator Moor is exactly what it implies ‘The Moor of Cleator’. Cleator is the village about one mile from the town and the origins of the village can be traced back to the 12th Century. Some of the explanations of the name have been given in various publications. These four are taken from the mid 1800’s and early 1900’s.

From Nicholson and Burns:

• Kekell from the river Kekell, and so the parish was called Kekeltere and by contraction Cleator
• From Whelen Directory 1860: “Probably the district derived its name from Ketel, the third Baron of Kendal”
• From Bulmers Directory 1901: “Cleator appears in old records as Kekleton, so named from the small river Keekle which bounds it on the West. The origin of the name has not as yet been ascertained with any degree of certainty. A rather distant resemblance in sound of the name of the third Baron of Kendal, Ketel, has been suggested the name of that feudal champion as the source of the word”
• From Cleator Past and Present by Caesar Caine, and reprinted by Michael Moon: He writes about a Richard Cleter, which appears in a document dated 1292. When quoting from a translation from 1315 he wrote: “Cleator was not spared, in 1315 a Lieutenant of Robert the Bruce, descended upon St Bees, Egremont and Cleator”

Cleator has also been written in differing styles throughout the centuries. Such as: 1175 Cletergh, 1322 Cleterne, 1338 Cletergh, 1539 Cletour, 1572 Cleter and 1900 Cleator (a derivation of the name Kekelterre, contracted to Cleator, i.e. The lands of the river Kekel).
