Cool History, Family Crest & Coats of Arms
The ancestors of the Cool family were part of an ancient Scottish tribe called the Picts. They lived in Coull, a parish, in the district of Kincardine O'Neil, county of Aberdeen. "This place is supposed to have taken its name, which signifies a "corner," from its situation in the south-eastern extremity of the district of Cromar." 
Early Origins of the Cool family
The surname Cool was first found in Aberdeenshire (Gaelic: Siorrachd Obar Dheathain), where one of the first records of the family was "William de Cull [who] was one of the witnesses to a charter by John, Earl of Huntington to Norman filius Malcolm of the lands of Lesslyn etc., between 1219-1237." 
Coull Castle was an 13th-century castle to the south of Coull. Only traces of the castle can be found today.
Some of the first records of the family in Scotland include: John Cowl who possessed a tenement in Glasgow in 1458, and Sir John Cowill, a cleric, was witness in Aberdeen, 1567. Patrick Coule at Newburgh is mentioned in the Lindores Chartulary in 1479. David Cowle, a native of Scotland, had letters of naturalization in England in 1481, and in the same year Alexander Coule was admitted burgess of Aberdeen." 
Further south in northern England, the Lay Subsidy Rolls of 1332 listed John de Couhill, of Rishton, Lancashire; and John de Coule, of Blackburn, Lancashire, 1332. 
"The Cowells of Lancashire probably take their name from Cowhill, a district and seat in Lancashire."

The freedom of the North American colonies was enticing, and many Scots left to make the great crossing. It was a long and hard journey, but its reward was a place where there was more land than people and tolerance was far easier to come by. Many of these people came together to fight for a new nation in the American War of Independence, while others remained loyal to the old order as United Empire Loyalists. The ancestors of Scots in North America have recovered much of this heritage in the 20th century through Clan societies and other such organizations. A search of immigration and passenger lists revealed many important and early immigrants to North America bearing the name of Cool:

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: Cole Deum
Motto Translation: Worship God.
