MacGriogair
MacGriogair is a Scottish surname, an Anglicized form of the Gaelic *Mac Griogair*. The Gaelic patronymic *Mac Griogair* translates to "son of Griogair". The personal name Griogair is derived from the Latin name Gregorius, which itself comes from the Greek word gregōr, meaning "watchful" or "vigilant". The MacGregors are one of the oldest Highland clans, with a history stretching back to the 13th century. Their traditional territory was around Loch Awe and Glen Orchy in Argyll. The clan has a complex and often turbulent history, marked by feuds with other clans and conflicts with the Scottish Crown. Notable historical figures associated with the name include Rob Roy MacGregor, a famous outlaw and folk hero. The surname MacGregor, and its variations such as MacGrigor or McGregor, is common throughout Scotland and has also spread to other English-speaking countries through emigration. The clan motto is "S'rioghal mo dhream" (My race is royal).
