This name is a good example of a developed form of surname which has moved completely away from its 'roots'. The origination is the Anglo-Saxon 'ceald' meaning 'cold' and 'cot' - a house or small dwelling. The first recording of what could be described as the forerunner of the modern spelling was Simon de Caldecot recorded in the Pipe Rolls of Cambridgeshire for 1195, in the short reign of Richard 1 'The Lionheart'. Later developments included William de Cheldecot (1225, Warwick) and Edmund de Caudecot of Kent in 1206. Later developments showing the 'link' to the present spelling include Will Cadlicatt of London, in 1710 and James Cadlett of Stepney in 1758. The present name spelling is very rare, only one 'root' recording being found before this century. The first recorded spelling of the family name is shown to be that of Frederich Cadlock, which was dated May 12th 1872, a witness at Christ Church Southwark, London, during the reign of Queen Victoria, 'The Great White Queen', 1837 - 1901. 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.
