The surname Cay is derived from the Breton and Old Welsh word "Cai," and the Cornish word "Key," both of which meant "wharf." This name became the Middle English given name Kay. Some instances of this surname are no doubt derived from the Old English "Coeg," which meant "key." 1

Early Origins of the Cay family

The surname Cay was first found in the Pipe Rolls for Northumbria where Britius filius Kay is listed there in 1199. Cecilia de Kay was in the Pipe Rolls for Gloucestershire in that same year. Another early record in the Pipe Rolls is of John del Cay in 1207 in London. John del Cai was Sheriff of London in 1201 and may be the same person as the aforementioned Pipe Roll entry. 2

The Hundredorum Rolls of 1273 list a Jordan Kay but the Yorkshire Poll Tax records of 1379 has the most entries of the time: Robertus Cay; Alanus Kay; Johanna Caa; and Willelmus Ka. 3

One reference claims a more romantic origin of the name: "the family of Kaye is of great antiquity in the county of York, being descended from Sir Kaye, an ancient Briton, and one of the Knights of the warlike Table of that noble Prince Arthur, flower of chivalry!!" 4

"The property [of Thornton in Craven in the West Riding of Yorkshire] belongs to various families, the principal owner being Sir John Lister Kaye, Bart., lord of the several manors." 5

"Kay or Kaye is the name of an ancient and distinguished family of Woodsome in the West Riding [of Yorkshire], one of whose members received a baronetcy from Charles I. The Kayes are now best represented in the Huddersfield district of the West Riding, whilst the Kays are more numerous in Lancashire. As far back as the 13th century we find this name, both as Kay and Kaye, in Lincolnshire, Hunts, and Cambridgeshire. 6
