MacKesay History, Family Crest & Coats of Arms
The ancestors of the MacKesay family brought their name to England in the wave of migration after the Norman Conquest of 1066. They lived in Sussex. Their name, however, is thought to be derived from a location in Normandy called Argenson, which would have been used as a name in its local form, D'Argenson, meaning from Argenson. The location, however, like many small settlements of the time, has been lost to the map in contemporary times. It is likely that the M now appears as the first letter of the name in most cases due to confusion with the similar metronymic name meaning son of Margaret. 
Early Origins of the MacKesay family
The surname MacKesay was first found in West Sussex where the family held estates in Offington. One source claims "John D'Argenson, living in 1449, had two sons, one of whom fought at the battle of Pavia, in 1524, and the other, Peter D'Argenson, was founder of the English branch. The Margetsons of Yorkshire sprang from that personage, which may well admit of question, for certainly D'Argenson and Margetson are not much alike." 
The Yorkshire Poll Tax Rolls of 1379 list: Robert Marjorison; Richard Marjorison; and Roger Margeryson.

MacKesay Spelling Variations
A multitude of spelling variations characterize Norman surnames. Many variations occurred because Old and Middle English lacked any definite spelling rules. The introduction of Norman French to England also had a pronounced effect, as did the court languages of Latin and French. Therefore, one person was often referred to by several different spellings in a single lifetime. The various spellings include Margesson, Margeson, Margerison, Margetson and many more.

Migration of the MacKesay family
Many English families left England, to avoid the chaos of their homeland and migrated to the many British colonies abroad. Although the conditions on the ships were extremely cramped, and some travelers arrived diseased, starving, and destitute, once in the colonies, many of the families prospered and made valuable contributions to the cultures of what would become the United States and Canada. Research into the origins of individual families in North America has revealed records of the immigration of a number of people bearing the name MacKesay or a variant listed above: Edward Margeson was one of the passengers on the " Mayflower" which arrived in 1620; Robert Margeson settled in Virginia in 1655; Joseph Margerison settled in Philadelphia in 1880..

The MacKesay Motto +
The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.
Motto: Loyalité me lie
Motto Translation: Loyality binds me.
