Recorded in many spellings as shown below, this is an English surname. It has two possible origins. Firstly, it may derive from the pre 7th Century personal name Tideman from "tid" meaning time, plus "mann," a man. Secondly it could be a status name for the head of a tithing, a group of ten households. According to the medieval system of frankpledge, every member of a tithing was responsible for every other, so that for example if one of them committed a crime the others had to help pay for it. The surname is first recorded in the early 14th Century, and examples include John Tytman in the Subsidy Rolls of Suffolk in 1524. In the modern idiom the surname spellings include Tidiman, Tiddeman, Tydeman, Titman, Tittman, and others. Later recordings from the London church registers include John Tiddeman who was christened on January 9th 1624, at St. Giles Cripplegate, and the marriage of Alice Tidiman and John Love on April 20th 1627, at St. Gregorys by St. Pauls cathedral. The first recorded spelling of the family name is shown to be that of John Tytheman. This was dated 1327, in t he Subsidy Tax Rolls of Suffolk, during the reign of King Edward 111rd, known as "The Father of the English Navy", 1327 - 1377. Surnames became necessary when governments introduced personal taxation. In England this was sometimes known as Poll Tax. Throughout the centuries, surnames in every country have continued to "develop" often leading to astonishing variants of the original spelling.
