Sigurd II "Digri" Hlodversson

Sigurd Hlodvirsson (circa 960 – 23 April 1014), popularly known as Sigurd the Stout from the Old Norse Sigurðr digri,[2] was an Earl of Orkney. The main sources for his life are the Norse Sagas, which were first written down some two centuries or more after his death. These engaging stories must therefore be treated with caution rather than as reliable historical documents.

The sources for Sigurd's life are almost exclusively Norse sagas, none of which were written down at the time of the events they record. The Orkneyinga Saga was first compiled in Iceland in the early 13th century and much of the information it contains is "hard to corroborate".

Sigurd also appears briefly in St Olaf's Saga as incorporated into the Heimskringla and in the Eyrbyggja Saga. There are various tales about his exploits in the more fanciful Njal's Saga as well as the Saga of Gunnlaugr Serpent-Tongue, Thorstein Sidu-Hallsson's Saga, the Vatnsdæla Saga and in the tale of "Helgi and Wolf" in the Flateyjarbók

The Orkneyinga Saga reports that Sigurd was the son of Hlodvir, one of the five sons of Thorfinn Skull-Splitter, and Eithne. She is said to be a daughter of a "King Kjarvalr". The period after Earl Thorfinn's death was one of dynastic strife; three of Earl Hlodvir's brothers ruled before him, although he died in his bed before being succeeded by Sigurd,[9][10] probably in the 980s.

Sigurd's patronymic is an unusual one and there would appear to be a connection with this name and the early roots of the modern French name "Louis"
