Clan Robertson
Clan Donnachaidh (Scottish Gaelic: Clann Donnchaidh), also known as Clan Robertson, is one
of the oldest of all Scottish clans. The clan's first recognised chief, Donnchadh Reamhar, "Stout Duncan", son of Andrew de Atholia (Latin "Andrew of Atholl"), was a minor
land-owner and leader of a kin-group around Dunkeld, Highland Perthshire, and as legend has it, an enthusiastic and faithful supporter of Robert I (king 1306–29) during the
Wars of Scottish Independence; he is believed to have looked after King Robert after the Battle of Methven in 1306.[citation needed] The clan asserts that Stout Duncan's
relatives and followers (not yet known as Robertsons) supported Robert the Bruce at the Battle of Bannockburn in 1314. His descendants became known (in English or Scots) as
the Duncansons, or Gaelic Clann Dhònnchaidh, "Children of Duncan". Duncan is believed to have been killed at the Battle of Neville's Cross and was succeeded by Robert, from
who the Clan Robertson takes its name. Robert's brother, Patrick, was the ancestor of the Robertsons of Lude who were the principal cadet branch.
