Leod (Scottish Gaelic: Leòd; Old Norse: Ljótr) ( 1200 – 1280) was the eponymous ancestor and founder of Clan MacLeod and Clan MacLeod of Lewis. Almost nothing is known about him and he does not appear in any contemporary records. Tradition dating to the late 18th century made him a son of Olaf the Black who was King of Man (r. 1225–1237). Heraldic evidence, dating to the late 17th century, is considered to be the earliest evidence of descent from Olaf the Black. However, in recent years, this traditional lineage has been challenged and is no longer considered fact by one historian.

According to Clan MacLeod tradition, Leod inherited some of his lands from a foster father, who was a sheriff of the Hebridean island of Skye; other lands he inherited from his father-in-law, who was also a lord on Skye. MacLeod tradition also states that Leod was the father of four sons and two daughters. Two of these sons founded the two main branches of MacLeods; branches which exist to this day—Tormod (from whom the MacLeods of Harris and Dunvegan descend) and Torquil (from whom the MacLeods of Lewis descend). The traditional belief that Torquil was a son has also been challenged; the current understanding is that he was a great-grandson of Leod. In recent years, the DNA evidence of men bearing surnames equating to MacLeod has revealed that a certain proportion share a common ancestor—an ancestor considered to have been the clan's founder.

Leod

Traditional ancestry

According to MacLeod tradition, Leod is the eponymous ancestor of the clan. However, little to nothing is known about this man; he does not appear in any contemporary records. The earliest historical record of a MacLeod chief occurs almost a century after he is thought to have flourished—when the names of "Malcolme, son to Tormode M'Cloyde", and that of "Torkyll M'Cloyd", appear in a royal charter during the reign of David II, King of Scots (r. 1329–1371). Until quite recently, Leod has generally been considered to have been the son of Olaf the Black, King of Mann and the Isles (r. 1225–1237).

Leod

This traditional ancestry may be traced to the late 17th century when a chief adopted the designation of "McOlaus" and another was the first MacLeod to incorporate the royal Manx arms into MacLeod heraldry. In a document dating to 1630, Iain Mòr MacLeod of Dunvegan (chief 1626–1649) appears as "John McOlaus of Dunvegane"—McOlaus representing MacOlaf. This chief's son, Iain Breac (chief 1664–1693), is the first MacLeod to have incorporated the Manx triskelion into his coat of arms. The triskelion was borne in the arms of the kings of Mann and the Isles as far back as the 13th century. The earliest known arms borne by the MacLeods of Harris and Dunvegan (pictured top-right) are, however, quite different the royal Manx arms. These earliest MacLeod arms date to the mid-15th century; recorded in a leading European armorial known as the Armorial de Berry. Accordingly, it has been suggested that these points show that 17th-century belief of a descent from Olaf was not one of long standing.

Leod

There are various other points which cast serious doubt on Leod's traditional ancestry. In 1265, Magnus, King of Mann, the last king of this Manx dynasty died. Later in 1275, Magnus's illegitimate son, Godfrey died while leading a revolt. At least two women later came forward with claims for the kingdom—yet Leod and his sons did not. According to W.D.H. Sellar, it is hard to believe that a descendant of the royal line would not have put forward a claim. Another point put forward is that the MacLeods did not adopt the royal names of the 13th century Manx dynasty—names such as Godfrey (Old Norse: Guðrøðr; Gaelic: Gofraid), Ranald (Old Norse Rögnvaldr; Gaelic: Raghnall), Olaf (Old Norse Óláfr; Gaelic Amlaíb), and Harald (Old Norse Haraldr; Gaelic Aralt). Sellar illustrated his point by noting the royal names adopted by the descendants of Somerled (d. 1164) and his wife Ragnhild, daughter of Olaf the Red (grandfather of Olaf the Black).
