Keithley History, Family Crest & Coats of Arms
The ancestors of the name Keithley date back to the Anglo-Saxon tribes of Britain. The name is derived from when the Keithley family lived in the settlement of Keighley in the West Riding of Yorkshire.   The surname Keithley belongs to the large category of Anglo-Saxon habitation names, which are derived from pre-existing names for towns, villages, parishes, or farmsteads.
Early Origins of the Keithley family
The surname Keithley was first found in Yorkshire at Keighley, a market-town and parish, and the head of a union, in the E. division of the wapentake of Staincliffe and Ewcross.  The first listing of the place name was Chichelai in the Domesday Book of 1086. 
"This place, anciently Kyghelay, was for many generations the property of the Kyghelay family, who either gave their name to, or derived it from, the manor; and of whom Gilbertus Kyghelay, of Utley, was buried here in 1203, according to an inscription on a stone still remaining in the parish church. In the reign of Edward I. Henry de Kyghelay, a member of the family, obtained the grant of a weekly market and an annual fair, with privilege of free warren for the inhabitants." 
The first on record was found in the Testa de Nevill, sive Liber Feodorum, temp. Henry III-Edward I. : Henry Kighele, Lancashire, I Edward III (during the first year of the reign of King Edward III.) 
Henry de Kythelay was also found in Yorkshire in the 14th century. 
Later the Yorkshire Poll Tax Rolls of 1379 listed Johannes de Kyghelay as holding lands there at that time.  A well-educated family, the Register of the University of Oxford had two early entries for the family: John Kighlye, Lincolnshire, 1576: and Philip Kyghley, or Kygleye, Worcestershire, 1583.
