The surname McCosley was first found in on the Isle of Uist, in the Hebrides in Scotland, which is named for the Irish King, Colla Uais who was deposed in Ireland by Muedach Tireach and was banished with 300 of their principal chiefs to the Hebrides in 327 A.D. They became known as the kingdom of Ailech and gave birth to the kindred of St. Columba and the Abbots of Iona. Descended were the Kings of Scotland from 1034 to 1286. The MacDonalds, Kings of the Isles were descended through Somerled to MacCuish or MacCooish.

Migration of the McCosley family
Scottish settlers arrived in many of the communities that became the backbones of the United States and Canada. Many stayed, but some headed west for the endless open country of the prairies. In the American War of Independence, many Scots who remained loyal to the Crown re-settled in Canada as United Empire Loyalists. Scots across North America were able to recover much of their lost heritage in the 20th century as Clan societies and highland games sprang up across North America. Early immigration and passenger lists have documented some of the first McCosleys to arrive on North American shores: John McCoosh settled in Pennsylvania in 1714.
