Robert "Rob" Roy MacGregor (Gaelic: Raibeart Ruadh MacGriogair; baptised 7 March 1671 – died 28 December 1734) was a Scottish outlaw, who later became a folk hero. The name Roy comes from Gaelic Ruadh meaning Red, and referred to his red hair. Rob Roy was born at Glengyle, at the head of Loch Katrine, as recorded in the baptismal register of Buchanan, Stirling. His parents were Donald Glas MacGregor and Margaret Campbell. He was also descended from the Macdonalds of Keppoch through his paternal grandmother. In January 1693, at Corrie Arklet farm near Inversnaid, he married Mary Helen MacGregor of Comar (1671-1745), who was born at Leny Farm, Strathyre. The couple had four sons: James, Ranald, Coll and Robert (known as Robin Oig or Young Rob). They also adopted a cousin named Duncan.
