Rob Roy MacGregor lived in Glen Shira for a short time under the protection of John Campbell, 2nd Duke of Argyll, also known as Red John of the Battles ("Iain Ruaidh nan Cath"). Argyll negotiated an amnesty and protection for Rob in 1716, and granted him permission to build a house in upper Glen Shira after disarmament. Records suggest that Rob Roy also constructed a fank for sheep or cattle in the Glen. However, some time after the 1719 Jacobite Rebellion — likely around 1720 — Rob moved to Monachyle Tuarach by Loch Doine, abandoning the structures. Nevertheless, ruins remain extant.
