Grants and donations of land at Mellerstain were made to both Durham Priory and Kelso Abbey, and some time between 1265 and 1285 William de Hattely granted the abbot of Kelso the right to pass through his lands of Meloustan (Mellerstain) and permission to build a bridge over the Blackburn above his house.
