The Cays surname is thought to have emerged from several different sources. In Northern England and Scotland, it comes from the Old Norse "ká," which meant "jackdaw." It also came from the Breton and Old Welsh word "Cai," and the Cornish word "Key," both of which meant "wharf." And, in some instances, this surname is no doubt derived from the Old English "Coeg," which meant "key."

Early Origins of the Cays family

The surname Cays was first found in Yorkshire, but the surname was also found in Lincolnshire, and Cambridgeshire as far back as the 13th century. One of the first records in Scotland was the Kae family of Croslats who were and "old family" of West Lothian. The Keay spelling was quite popular in Perthshire. Philip Qua was listed in Aberdeen in 1317 and Donald Ka was listed there too in 1399. Thomas Kaa was on an inquest taken at Berwick-on-Tweed in 1370. Patrick Ka was burgess of Linkithgow until his death in 1445. 1 The "Mac" prefix seems is difficult to clarify. Some Mackay (Macaoid) families may have shortened their name.

The Cays Motto +

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.

Motto: Kynd Kynn Knawne Kepe
Motto Translation: Keep your own kin-kind.
