When the ancestors of the Mackly family emigrated to England following the Norman Conquest in 1066 they brought their family name with them. They lived in Lincolnshire, where they held a family seat at Claye. The place name literally means "dweller at the clayey place." 1

Early Origins of the Mackly family

The surname Mackly was first found in Lincolnshire where the Hundredorum Rolls of 1273 list William del Cley and Robert del Clay as holding lands there at that time. The same rolls also listed Alicia in le Clay, Huntingdonshire. 2

Later, in Yorkshire, the Yorkshire Poll Tax Rolls of 1379 included: Agnes del Clay; Johannes del Clay; and Adam del Clay, Howdenshire. 2

"Clay has long been a Nottinghamshire surname. It was represented in the parish of Hayton in the time of Henry VII. Hercules Clay was a mayor of Newark in the reign of Charles I. (S.), and Clay is still a Newark name. The Clays of Southwell during last century carried their pedigree back 200 years, and their name is yet in the town. Six centuries ago Clay was a common name in the east of England, especially in Essex, Lincolnshire, Hunts, Cambridgeshire, and Beds. It is still well established in Lincolnshire, as well as in Nottinghamshire and Derbyshire." 3

Mackly Spelling Variations

The English language only became standardized in the last few centuries. For that reason, spelling variations are common among many Anglo-Norman names. The shape of the English language was frequently changed with the introduction of elements of Norman French, Latin, and other European languages; even the spelling of literate people's names were subsequently modified. Mackly has been recorded under many different variations, including Clay, Claye, Cley, Cleye, McClay and others.

United States Mackly migration to the United States +

To escape the uncertainty of the political and religious uncertainty found in England, many English families boarded ships at great expense to sail for the colonies held by Britain. The passages were expensive, though, and the boats were unsafe, overcrowded, and ridden with disease. Those who were hardy and lucky enough to make the passage intact were rewarded with land, opportunity, and social environment less prone to religious and political persecution. Many of these families went on to be important contributors to the young nations of Canada and the United States where they settled. Macklys were some of the first of the immigrants to arrive in North America:

  • David Mackly, who arrived in Pennsylvania in 1742 5


The Mackly 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: Per orbem
Motto Translation: Through the world.
