This surname has a number of interesting derivations. Firstly, it may be of early medieval English origin, from a Middle English given name "Cade", apparently deriving from a Germanic root meaning "something lumpy or protruding", plus the second element "mann", man, but in this context usually meaning "servant of", hence "Cade's servant". Secondly, the name may be an occupational name for a cooper, from the Old French, Middle English "cade", a cask, barrel. Finally, the surname may have originated as a nickname for an inoffensive, gentle person, from the Middle English "cade", a domestic animal, pet. The surname itself is first recorded in Cambridgeshire in the late 13th Century (see below), while Eustace Cade is recorded in the Pipe Rolls of Lincolnshire in 1189. Geoffrey Cademan is mentioned in the Subsidy Rolls of Derbyshire in 1327, while Thomas Cademain and Robertus Cadman are mentioned in the Poll Tax Records of Yorkshire in 1379. Sir Thomas Cademan (1590 - 1651) was physician to Queen Henrietta Maria, and held patents for distilling strong waters and vinegar. A Coat of Arms was granted to a Cadman family at Cowley in Derbyshire which depicts three green columbine buds on a gold shield, with a Crest consisting of a stork's head royally crowned proper. The first recorded spelling of the family name is shown to be that of Robert Cademan, which was dated 1279, in the "Hundred Rolls of Cambridgeshire", during the reign of King Edward 1, known as "The Hammer of the Scots", 1272 - 1307. Surnames became necessary when governments introduced personal taxation. In England this was known as Poll Tax. Throughout the centuries, surnames in every country have continued to "develop" often leading to astonishing variants of the original spelling.
