McGuffin History, Family Crest & Coats of Arms
The distinguished surname McGuffin emerged among the industrious people of Flanders, which was an important trading partner and political ally of Britain during the Middle Ages. As a result of the frequent commercial intercourse between the Flemish and English nations, many Flemish migrants settled in Britain. In early times, people were known by only a single name. However, as the population grew and people traveled further afield, it became increasingly necessary to assume an additional name to differentiate between bearers of the same personal name. One of the most common classes of surname is the patronymic surname, which was usually derived from the first name of the person's father. Flemish surnames of this type are often characterized by the diminutive suffix -kin, which became very frequent in England during the 14th century. The surname McGuffin is derived from Giff, a pet form of the personal name Geoffrey. This pet form is supplemented by the diminutive suffix -on or -in.
Early Origins of the McGuffin family
The surname McGuffin was first found in North Ayrshire where the Barony of Giffen was in the parish of Beith in the former District of Cunninghame. Giffen Castle is today in ruins but the castle was home to the Lordship of Giffin, which included the Baronies of Giffen, Trearne, Hessilhead, Broadstone, Roughwood and Ramshead dating back to the 15th century. It fell into disrepair soon after 1726 and finally collapsed in 1838.
Further to the south, "the Subsidy Rolls of Worcestershire (1327) and Warwickshire (1332) contain at least 40 surnames [with the] -en [suffix.] "  By example, Peter and Rose Geffen were listed in the Subsidy Rolls for Warwickshire in 1332. Willelmus Gyffon was listed in the Yorkshire Poll Tax Rolls of 1379.

McGuffin Spelling Variations
Flemish surnames are characterized by a large number of spelling variations. One reason for this is that medieval English lacked definite spelling rules. The spellings of surnames were also influenced by the official court languages, which were French and Latin. Names were rarely spelled consistently in medieval times. Scribes and church officials recorded names as they sounded, rather than adhering to specific spelling rules, and people often had their names registered in several different forms throughout their lives. One of the greatest reasons for change is the linguistic uniqueness of the Flemish settlers in England, who spoke a language closely related to Dutch. The pronunciation and spelling of Flemish names were often altered to suit the tastes of English-speaking people. In many cases, the first, final, or middle syllables of surnames were eliminated. The name has been spelled Giffin, Giffen, Geffen, Giffan, Giffon, Geffan, Geffon, Giffines, Giffins, Giffans, Giffons, Whiffen, Whiffin, Wiffin, Wiffen, McGiffen and many more.
