Aldey History, Family Crest & Coats of Arms
In ancient Scotland, Aldey was a Strathclyde-Briton name for someone who lived near the mountain called, Holy Day, in the county of Annandale. However, some sources claim the "name is derived from the slogan or war cry of the family 'a holy day, a holy day.' "  
Early Origins of the Aldey family
The surname Aldey was first found in Annandale. "The Hallidays of Hoddom, Dumfriesshire, were an old family there, and probably gave their name to Halliday Hill in the parish of Dalton." 
One of the first records of the family was found in 1303, when Adam de Halide was a juror on inquest at St. Andrews. A few years later, John Halyday was an archer of the East March in 1404 and Ambrose Halyday and David Halyday were merchants in Edinburgh in 1479. 
Despite the general understanding that the family was Scottish in origin, early records in England, specifically the Hundredorum Rolls of 1273, list Richard Haliday in Buckinghamshire and Gerard Haliday in Suffolk. Later, the Yorkshire Poll Tax Rolls of 1379 listed: Willelmus Haliday, Johannes Halyday, and Adam Halyday.  The reader should be reminded that Yorkshire's proximity to the Scottish border probably points to the aforementioned Scottish origin as the borders were extremely mercurial.
One romantic source notes: "A well-known Scottish Border Clan, who from their great animosity against the Southron are said to have adopted the war-cry or slogan of A Holy Day, (Scottice, 'a Haly Day'), because the chiefs and people of Annandale, whenever they made a raid or foray upon the Saxon border, accounted the day spent in rapine and slaughter a holy one."

Aldey Spelling Variations
Prior to the first dictionaries, scribes spelled words according to sound. This, and the fact that Scottish names were repeatedly translated from Gaelic to English and back, contributed to the enormous number of spelling variations in Scottish names. Aldey has been spelled Halliday, Haliday, Holyday, Holiday, Holliday, Halidays and many more.

Migration of the Aldey family
In such difficult times, the difficulties of raising the money to cross the Atlantic to North America did not seem so large compared to the problems of keeping a family together in Scotland. It was a journey well worth the cost, since it was rewarded with land and freedom the Scots could not find at home. The American War of Independence solidified that freedom, and many of those settlers went on to play important parts in the forging of a great nation. Among them: Joseph Halliday settled in Barbados in 1686; John Halliday settled in Maryland in 1775; James Halliday settled in Petersburg, Virginia in 1822, along with his father David..
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: Quarta saluti
Motto Translation: The fourth to health.
