This rare and interesting surname is a variant of Trustrie, which is itself a variant of Tristram, which is of Scottish origin. The name is derived from the Celtic personal name "Drystan", from "drest, drust", tumult, din and it appeared in Scotland as a personal name from the end of the 12th Century, usually in the form Tristram. The personal name was first recorded as "Tristrannus" in the Charters bulls, and other documents relating to the Abbey of Inchaffray, Scotland in 1200. The surname development since 1207 (see below) includes the following: Richard Trustram (1577, Norfolk), Thomas Trustrie (1600, Scotland) and Thomas Trustey (1645, London). The modern surname can be found as Tristram, Trustram, Trustrie, Trustie, Trustey and (Mc) Trusty. Among the recordings in Scotland are the christening of William Hugh, son of Hugh McTrusty and Martha Eaton, on September 10th 1871 at Old Monkland, Lanarkshire, and the marriage of Richard McTrusty and Jane Bell on July 15th 1875 at Gorbals, also in Lanarkshire. The first recorded spelling of the family name is shown to be that of Henry Tristram, which was dated 1207, in the Pleas before the Kings or his Justices, Essex, during the reign of King John, known as "Lackland", 1199 - 1216. 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.
