According to MacLeod tradition, Leod had two sons—Tormod and Torquil. The tradition is that Tormod was the ancestor of the MacLeods of Harris and Dunvegan (the chiefs of Clan MacLeod), and Torquil was the ancestor of the MacLeods of Lewis. The "Bannatyne manuscript" does not specifically state which son was the elder, and subsequently there has been debate over which branch was more 'senior' in descent. In the late 20th century, Matheson called into question this tradition of brothers, and his work was followed up by other historians. The current view of historians is that the two were not brothers at all; but that Torquil was actually the grandson of Tormod.
