This is a locational name which derives from either the Village of Trotton in Sussex or Troughton in Lancashire, both having the same meaning and origin. The name is Olde English pre 10th Century and translates as "the Farm of Traett", the latter being a pre Domesday personal name which means "The defiant one". In the modern idiom the surname has several spelling forms including Trotton, Tritton and Trittam. The spelling development would seem to be Troughton or Trotton to Trighton to Trittam. Mary Trittam being baptised in 1624 (London), whilst in 1728, Susan Tritton married John Horne, also in London. The first recorded spelling of the family name is shown to be that of Thomas Trighton, which was dated 1555, who married Jane Mossel, of London, during the reign of Queen Mary 1, known as Bloody Mary, 1554 - 1558. 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.
