"A parish in Berwickshire, in the district of Merse, of a triangular shape, containing about 7200 acres. The surface rises from the E. and S. towards the N. where the highest ground is named Langton Edge, from whence the prospect over the low land in Berwickshire and Northumberland is very extensive ... The ancient village of Langton was a long straggling town, as its name implies: it suffered like the rest of the border towns from the incursions of the English, having been burnt in 1558 by Sir Henry Percy and Sir George Bowes, and at other times by the marauding parties from Berwick and Northumberland. Mr George Gavin, the late proprietor, finding a dirty town so near his house an obstacle to improvements, offered the inhabitants to feu, on easy terms, a piece of ground, in a pleasant situation, about half a mile distant. This offer was accepted, and the old town of Langton in a short time disappeared, and the new and thriving village of Gavintown arose in its room ... Population in 1801, 428."
