[1] William Fraser, writing in the 19th century gives a similar account but states that Hugh was actually the son of Freskin, rather than his grandson.

[3] According to John Stewart-Murray, 7th Duke of Atholl, Hugo or Hugh de Moravia was the second son of Freskin.

Fraser concludes that it is probable that in this period King Alexander conferred the title of earl upon William, Lord of Sutherland.

However, they did not always agree as before the bishop's death in 1245 a feud took place between them over certain lands and although an agreement was reached, it was not settled in their day and was continued by their successors.

[8] Sir Robert Gordon relates the story of the Battle of Embo where William, Earl of Sutherland sent his retainer, Richard de Moravia, brother of Bishop Gilbert, to keep a force of marauding Norwegian invaders in check until he could raise a large enough force to do battle.

[8] According to Sir Robert Gordon, William de Moravia, 1st Earl of Sutherland died in 1248 and was buried in the south aisle of Dornoch Cathedral.
