A tower is marked on mid-17th century maps as Sownout (Gordon) and Sounwoode (Blaeu) in the vicinity of East and West Reston. Its exact location is unknown so I have placed it at Swinwood Mill for now pending further research.
Sounwoode; Sownout; Suineston; Swinewood; Swynewode
Swinwood is in the parish of Coldingham and the county of Berwickshire.
