This ancient and interesting name is of Anglo-Saxon origin, and is a "status" name given to the head of a tithing, group of ten households. The name derives from the Old English pre 7th Century "teothingmann", from "teothing", tithing, group of households, with "mann", man. In the medieval system called "frankpledge", every member of a tithing was responsible for every other, so that if, for example, one of them committed a crime, the others had to help pay for it. In some few cases, the surname may derive from the Old English given name "Tideman", composed of the elements "tid", time, season, with "man", man. The surname development includes John Tytheman (1327, Suffolk), and John Tytman (1524, ibid.). The modern surname can be found as Tidman, Tiddeman, Tydeman, Titman, and Tittman. The marriage of Thomas Tydeman and Anne Porter was recorded at St. James's, Duke's Place, London, on September 21st 1690. The first recorded spelling of the family name is shown to be that of William Tedingman, which was dated 1193, The Wiltshire Pipe Rolls, during the reign of King Richard 1, "The Lionheart", 1189 - 1199. 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.
