Herdey History, Family Crest & Coats of Arms
The first family to use the name Herdey lived in the ancient Scottish kingdom of Dalriada. It was used as a nickname for a brave person. This surname is a nickname, which belongs to the category of hereditary surnames. Nicknames form a broad and miscellaneous class of surnames, and can refer directly or indirectly to one's personality, physical attributes, mannerisms, or even their habits of dress. The surname Herdey comes from the Old French and Old English word hardi, which means brave. 
Another source claims that the name was originally Norman as the Magni Rotuli Scaccarii Normanniae lists Roger, Hunfrid, Robert and Nicholas Hardi in Normandy, 1180-1195. 
Early Origins of the Herdey family
The surname Herdey was first found in Lanarkshire (Gaelic: Siorrachd Lannraig) a former county in the central Strathclyde region of Scotland, now divided into the Council Areas of North Lanarkshire, South Lanarkshire, and the City of Glasgow.
"The home county of the MacHardies is the Highlands of Aberdeenshire and the immediate neighborhood north and south, but with some few unimportant exceptions they did not own land on Deeside. They were, however, numerous and influential. The Strathdon branch counted themselves of the Clan Chattan and followed Macintosh as their chief. Dr. Macbain suggested that the name came from Pictish Gartnaigh, pronounced Gratney, a well-known name of old in Mar. (There was an earl of Mar called Gartney or Gratney about 1300.) He thinks it was developed to MacCardney or MacCarday, and ultimately before 1587 to MacHardy." 
Further to the south in England, the root of the name was more often than not found. The Hundredorum Rolls of 1273 listed Thomas Hardi (with no place of origin) and later, Thomas Hardy was listed in the Yorkshire Poll Tax Rolls of 1379. 
"We learn from the Hundredorum Rolls that six centuries ago, Hardi or Hardy was also an east country name, occurring then in the counties of Norfolk, Bedfordshire, Cambridge, Huntingdonshire, etc. " 
Over in Ireland, "the ubiquitous English surname Hardy in Ireland often conceals an ancient Gaelic Irish name MacGiolla Deacair. Deacair is the Irish word for hard. The early Anglicized form of this name was Macgilledogher. This is now obsolete and in the absence of a reliable pedigree, or at least of a well established family tradition, it is not possible to distinguish between Hardys of English and Hardys of Irish origin. " 
The famous English novelist and poet Thomas Hardy (1840-1928), hailed from Stinsford, Dorset, England where his father Thomas Hardy (1811-1892) worked as a stonemason and local builder.

Migration of the Herdey family
Significant portions of the populations of both the United States and Canada are still made up of the ancestors of Dalriadan families. Some of those in Canada originally settled the United States, but went north as United Empire Loyalists in the American War of Independence. The late 19th and early 20th centuries saw the ancestors of many Scots on both sides of the border begin to recover their collective national heritage through Clan societies and highland games. Some of the first North American settlers carried this name or one of its variants: Elizabeth Hardey settled in Rappahannock Virginia in 1725; Robert Hardey settled in Maryland in 1774; John Hardy settled in Salem in 1630; Thomas Hardy settled in Virginia in 1642.
