Many Flemings were attracted to Scotland during the 12th Century. One of them, named Freskin, obtained the lands of Strathbrock, in Linlithgowshire, later termed Broxburn, as a reward for his valour against an insurgent band in Morayshire. Some time around 1130, he received a grant of land in that county. His descendants, settling there, assumed the name of de Moray or de Moravia.
The Moryquhat, or Murraythwaite branch, flourished in Dumfriesshire during the 13th Century. Sir William Murray, of Cockpool, who lived in the reign of Alexander III, married Isobel, sister of Thomas Randolph, Earl of Moray. Their son, William, received a charter of the barony of Comlongan and Ryvil, from his uncle Randolph. The family was ennobled about 1623, in the person of Sir John Murray of Lochmaben, created Earl of Annandale. This Sir John's grandmother, Janet Jardine, after the death of Sir John's grandfather, married John Carruthers, 1st Baron Holmains, and was the progenitor of a line of Carruthers that eventually emigrated to America.
