"BOLTON, a parish in Haddingtonshire, bounded by the parishes of Haddington, Gifford, Humbie, and Salton. Its post-town is Haddington, 2 3/4 miles north of the church. The length of the parish northward is nearly 6 miles; and the average breadth is not more than about 1 1/4 mile. Gifford or Coalstone Water, a stream of much gentle beauty, flows along the north-eastern and northern boundary; and Binn's Water, from about the point of its debouch from the Lammermoors, flows along the southern boundary. The surface of the parish is agreeably diversified with undulations, but does not contain any upland or hill ... Population in 1831, 332; in 1861, 332." [From the Imperial Gazetteer of Scotland, edited by John Marius Wilson, 1868]
