Uisdean Macdonald

Hugh of Sleat (c. 1437 – 1498), pronounced "Slate", who is known as Ùisdean (Scottish Gaelic pronunciation: [ˈuːʃtʲan]) in Gaelic, was an illegitimate son of Alexander MacDonald, 10th Earl of Ross and Lord of the Isles. He was a member of the Highland and Western Isles Clan Donald. Hugh's clan later became known as Clan Uisdean, Clan Donald North, and Clan Macdonald of Sleat, while the McDonnells of County Antrim in Northern Ireland were known as Clan Donald South.

Hugh was probably born about 1436, the year when his father married his mother, a daughter of Gillepatrick Roy, son of Rory, son of the Green Abbot of Applecross, of the O'Bealon family, former Earls of Ross. The O'Bealon family also has been known as Ross and Rose and has connections to the Leslie family through marriage.

Hugh was probably born in Dingwall Castle, just outside Inverness, Scotland, the same castle where Macbeth of Scotland, of Shakespeare fame, was born. This was long the seat of the Earls of Ross. He most likely died at Paisley Abbey, in Paisley, Scotland, in 1498, and was buried at a place called Sand, on the island of North Uist. This burial ground is now called Clachan Shannda, Clachan meaning "a small village with a church", and Shannda meaning "Sand" or "Sand Island", from the Norse.

John, last Lord of the Isles from the McDonald line, was the brother of Hugh and received the lordship in 1449, when Alexander died at Dingwall. There is some controversy over the exact date, but it appears that John gave Hugh a charter to the lands of Sleat on the Isle of Skye, off the western coast of Scotland, during the year 1449. John would then have been about fifteen years old, so would have needed the blessing of his council. Hugh was probably thirteen years old when he first became Hugh of Sleat.
