The surname of HEATLIE was a locational name 'of Heatley' a spot in County Cheshire. Local names usually denoted where a man held his land and indicated where he actually lived. The name was taken to Scotland by early settlers and William de Hatteley, and Matilda, his wife, with her consent, granted to the monks of Kelso a right of way through his land of Mellerstan, and permission to build a bridge over the Blackburn. A Robert de Hetley, who possessed lands in Faunes and Melockstan, witnessed a charter in 1270. The burghs of Scotland owe much of their prosperity to the large immigration of foreigners which went on during the 12th and 13th centuries. The original founders of the towns, were in many cases wanderers from Flanders, who brought with them their habits of industry and knowledge of trade and manufactures. Settlers of this description came in great numbers to England in the reign of Henry I (1100-1135) and when Henry II (1154-1189) drove all foreigners out of his dominions they flocked into Scotland, where a more enlightened policy made them welcome. Other records of the name mention Hethileg (without surname) 1286 County Cheshire. Johannes de Hethele, listed in the Yorkshire Poll Tax of 1379. Johanna de Hetlegh, 1379 ibid. William de Hetley was one of the men-at-arms in the garrison at Roxburgh Castle in 1335 to 1377, and William Hatle, a Scottish merchant was given permission to have a safe conduct to travel into England in the year 1412.
