“In the parish of Borthwick, Midlothian, is Catcune, on the right bank of Gore Water, in 1296 ‘Thomas de Catkune,’ etc.;  in Blaeu Cathkin; in Retours Catcun, Cotcun, Cattun, Caltun, Caltoun. Here, then, we have a glimpse of the Gaelic people settled round their coitchionn or common pasture at some time, probably not very long before the time of Thomas de Catkone. There appear also ‘the land of the Lord of Borthwick called Catkunyslandis, under the burgh, territory, and burgage of Lauder.’ (22) Lauder still possesses extensive common lands which may be the lands here referred to but I am not sure that the reference is Catcune in Borthwick. The might be expected to be fairly common, but the only other instance known to me is Cathkin in Carmunnock near Glasgow.” Watson 1926, 136
