Blyth History, Family Crest & Coats of Arms
The saga of the name Blyth begins with a Strathclyde-Briton family in the ancient Scottish/English Borderlands. It is a name for a happy or cheerful person having been derived from the Old English word blithe.  
Alternatively, the name could have originated at Blyth in Northumberland or in the West Riding of Yorkshire. Both parishes derive their name from the Old English "blithe," meaning "the gentle or pleasant one."  The Yorkshire parish anciently in Nottinghamshire is the oldest dating back to the Domesday Book of 1086 where it was recorded as Blide. 
Another source notes "This place, anciently called Blia and Blida, was chiefly noted in former times for its religious and charitable establishments. In 1088, a priory was founded in honour of the Blessed Virgin, by Roger de Builly and his wife Muriel, for monks of the Benedictine order; which, though considered as an alien priory, being in some respects subordinate to the abbey of the Holy Trinity, near Rouen, in Normandy, was yet spared at the suppression of alien priories, and subsisted till the general dissolution, when its revenue was estimated at £126. 8. 2. An hospital for lepers, dedicated to St. John the Evangelist, was founded by Hugh de Cressy, lord of Hodsock, in the reign of John." 
Early Origins of the Blyth family
The surname Blyth was first found in Berwickshire an ancient county of Scotland, presently part of the Scottish Borders Council Area, located in the eastern part of the Borders Region of Scotland. Blyth was an old barony in the lordship of Lauderdale some time ago.
The first on record was of William de Blyth of Chirnesyde in Berwickshire who represented the family and rendered homage to King Edward I of England on his brief conquest of Scotland in 1296.
A few years later, the seal of Adam de Blyth was appended to an account of goods purchased at Perth in 1302. James Blyth was burgess of Dundy (Dundee) in 1485. 
Further south in England, Blythe, Lancashire has an interesting history. It was originally held by Geoffrey Travers, whose son Henry, was called "de Blythe." Henry de Blythe's descendants "John and Robert de Blythe occur among the names of subscribers to the stipend of a chaplain at Ormskirk in 1366 and the latter also in the Poll Tax Roll of 1381. John de Blythe attested Scarisbrick charters in 1399 and 1401, and was the father of Roger, who in 1397 was charged with breaking into the parsonage house at Crossens. From him descended Roger Blythe, whose daughter and heir Margaret by her marriage with John Blakelache (or Blackledge) conveyed the estate to this family. " 
Another source notes, William de Blithe was listed in the Hundredorum Rolls of 1273 in Oxfordshire and Willelmus de Blythe was listed in the Yorkshire Poll Tax Rolls of 1379.

Blyth Spelling Variations
Spelling and translation were hardly exact sciences in Medieval Scotland. Sound, rather than any set of rules, was the basis for spellings, so one name was often spelled different ways even within a single document. Spelling variations are thus an extremely common occurrence in Medieval Scottish names. Blyth has been spelled Blythe, Bllyt, Blytht, Blyithe, Blith, Blyth, Blitht and many more.

Migration of the Blyth family to Ireland
Some of the Blyth family moved to Ireland, but this topic is not covered in this excerpt.
Such hard times forced many to leave their homeland in search of opportunity across the Atlantic. Many of these families settled along the east coast of North America in communities that would become the backbones of the young nations of the United States and Canada. The ancestors of many of these families have rediscovered their roots in the 20th century through the establishment of Clan societies and other patriotic Scottish organizations. Among them:

Emigration to New Zealand followed in the footsteps of the European explorers, such as Captain Cook (1769-70): first came sealers, whalers, missionaries, and traders. By 1838, the British New Zealand Company had begun buying land from the Maori tribes, and selling it to settlers, and, after the Treaty of Waitangi in 1840, many British families set out on the arduous six month journey from Britain to Aotearoa to start a new life. Early immigrants include:

The British first settled the British West Indies around 1604. They made many attempts but failed in some to establish settlements on the Islands including Saint Lucia and Grenada. By 1627 they had managed to establish settlements on St. Kitts (St. Christopher) and Barbados, but by 1641 the Spanish had moved in and destroyed some of these including those at Providence Island. The British continued to expand the settlements including setting the First Federation in the British West Indies by 1674; some of the islands include Barbados, Bermuda, Cayman Island, Turks and Caicos, Jamaica and Belize then known as British Honduras. By the 1960's many of the islands became independent after the West Indies Federation which existed from 1958 to 1962 failed due to internal political conflicts. After this a number of Eastern Caribbean islands formed a free association.
