Halladay History, Family Crest & Coats of Arms
The roots of the name Halladay are found among the Strathclyde-Briton people of the ancient Scottish/English Borderlands. Halladay was originally found 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 Halladay family
The surname Halladay 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."

Halladay migration to the United States +
The freedom, opportunity, and land of the North American colonies beckoned. There, Scots found a place where they were generally free from persecution and where they could go on to become important players in the birth of new nations. Some fought in the American War of Independence, while others went north to Canada as United Empire Loyalists. The ancestors of all of these Scottish settlers have been able to recover their lost national heritage in the last century through highland games and Clan societies in North America. Among them:

The Halladay 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: Quarta saluti
Motto Translation: The fourth to health.
