In 1451 he had received a charter from the burgesses of Dingwall for land and a mill near Robert's Bridge (pontem Roberti de Munroo supra Peffery).
In 1505/6 he resigned the lands of Kildun to the Abbot of Dunfermline who granted them the following month to his son and heir, William Dingwall.
William Dingwall took part in the rebellion of Sir Donald during the regency which followed the death of James IV of Scotland at the Battle of Flodden in 1513.
Through his mother, Thomas Dingwall of Kildun inherited the lands of Lochalsh, Lochbroom, Kishorn, and Ferinkoskry in Braychatt.
In 1554 half of Lochalsh went by wadset to Kenneth, son of John Mackenzie of Kintail and finally sold to them in 1571.
In 1571, Thomas Dingwall gave a charter to Alexander Bayne of Tulloch and Anne Fraser his wife for half of the lands of Torridon.
He had married Janet Hay in 1533/4 and had at the same time part of the lands of Kildun granted to them by George Durie the Abbot of Dunfermline.
In 1589, he was accused, along with his servant, Donald Dingwall, of wounding Alexander Bane the younger in Knokinbaxter, and again for taking John MacInogach in Mekel Oussie and holding him bound in Kildun for 48 hours.
