Stuart made him Lord Macdonell in the Jacobite peerage. Following Alasdair Dubh's death (c. 1721 or 1724), he was eulogized in the song-poem Alistair à Gleanna Garadh by his kinswoman Sìleas na Ceapaich, which hearkens back to the mythological poetry attributed to Amergin Glúingel and which remains an iconic and oft imitated work of Scottish Gaelic literature. General Wade's report on the Highlands in 1724, estimated the clan strength at 800 men. Glengarry's Regiment served throughout the 1745 Rising, initially led by Aeneas, Glengarry's second son; he was accidentally shot dead after Falkirk and replaced by his kinsman Lochgarry who commanded at the Battle of Culloden. His elder brother Alastair Ruadh, later 13th Chief of Glengarry, was captured in November 1745 by a Royal Navy frigate while travelling from France to join the Rising. Imprisoned in the Tower of London, he was released in 1747 and at some point became a Hanoverian mole inside the Jacobite Movement, with devastating results. While his motivations are still disputed, Scottish historian Andrew Lang confirmed in 1747 that Alistair Ruadh was in fact 'Pickle the Spy'. The Highland Clearances of the early 19th century forced the majority of Clan MacDonell of Glengarry into exile; most settled in Glengarry County, Ontario and parts of Nova Scotia. The most systematic evictions were ordered by the 15th chief, Alexander Ranaldson MacDonell of Glengarry, who was allegedly the model for the haughty and flamboyant Scottish clan chief Fergus MacIvor in Walter Scott's 1814 novel, Waverley. In June 1815, Glengarry formed the Society of True Highlanders, a rival to the Celtic Society of Edinburgh; he was closely involved in arguments over precedence before, during, and after George IV's visit to Scotland in 1822. The occasion is best remembered for popularising the idea of tartans and Highland dress. His kinsman Fr. Alexander MacDonell (1762–1840) became a Catholic priest in Lochaber. In 1794, during the French Revolutionary Wars, Fr. Macdonnell became the first Catholic military chaplain in post-Reformation British military history after helping to raise the Glengarry Fencibles, which was disbanded in 1804. Father MacDonell accompanied his clansmen to Glengarry County, Ontario, where he helped resurrect the regiment for active service in the War of 1812. In 1826, he was appointed first Bishop of the local Diocese of Kingston. Castles Invergarry Castle which is situated on the Raven's Rock was the seat of the Chief of Clan MacDonell of Glengarry.
