Clan MacQuarrie Clan MacQuarrie (also MacQuarie, McQuary, MacQuaire, MacGuarie, Macquarie) is an ancient Highland Scottish clan which owned the islands of Ulva, Staffa and Gometra as well as large tracts of land on the Isle of Mull, which are all located in the Scottish Inner Hebrides. Clan MacQuarrie ("Scottish Gaelic" for: son of Guaire) is one of the seven Siol Alpin clans descended from the Kings of the Picts and Dál Riata. Clan MacQuarrie is one of the four oldest Highland clans and can trace its ancestry to 9th century Kenneth MacAlpine, the first King of Scots. According to the nineteenth-century historian William F. Skene, the "manuscript of 1450" documents the royal descent of Clan MacQuarrie through their progenitor "Guaire" ("Scottish Gaelic" for: noble), brother of "Fingon" (ancestor of Clan MacKinnon) and "Anrias" (ancestor of Clan Gregor). They were fierce fighters in the Wars of Scottish Independence and fought in support of King Robert the Bruce at the Battle of Bannockburn in 1314.
