Cochrane is a surname with multiple independent origins, two Scottish and one Irish. One Scottish version originates from a place in Scotland, and both the Irish surname and the other Scottish surname are anglicisations for a Gaelic language surname.
The name Cochrane originates from a habitational name derived from the "Lowlands of Cochrane", near Paisley in Renfrewshire. The derivation of the place name is uncertain. One possibility is that it is derived from the Welsh coch meaning "red"; however this theory is not supported by the early spelling of the name Coueran. Early recorded bearers of the surname are Waldeve de Coueran in 1262; William de Coughran in 1296; and Robert de Cochrane in about 1360.
The surname is especially concentrated in England in the counties of Durham in the North of England and Kent in the south. In Scotland, Cochrane is found in high frequency in the counties of South Lanarkshire, West Lothian and in Renfrewshire. The surname is the 784th most common last name in the United Kingdom. There are a number of spelling variations including Cochran, Cockren, and Coughran.
Together Scotland and England have the highest percentage of the Cochrane surname anywhere in the world. In Ireland, the surname Cochrane is especially concentrated in the northern province of Ulster where it was introduced by Protestant Scots settlers during the Plantation period of the 17th century. It was also adopted as an anglicisation by some Corcoran families.
In Northern Ireland, the surname Cochrane is concentrated in the counties of Antrim, Londonderry, Down and Tyrone. James Cochrane, an Ulsterman, was a 19th-century entrepreneur who helped the Northern Irish whiskey Bushmills and the Old Bushmills Distillery gain world wide popularity.
In the United States of America, the first Cochranes arrived amongst the Ulster-Scots immigrants to the British North American colonies of New Hampshire and Pennsylvania. Some of the earliest Cochranes in the United States came from County Antrim, Northern Ireland, in the early 18th century after obtaining a land grant from the Governor of Massachusetts. Later Cochranes would arrive from Scotland and England.
