Borthwickbrae, an estate, with a modern mansion, in the Selkirkshire section of Roberton parish, on the left side of Borthwick Water, 1½ mile SW of Roberton church. A graveyard here, the site of an ancient chapel, serves still as the principal burial-place of the parish; hence Borthwickbrae is sometimes called Kirk-Borthwick.
