context_page_description: Donnchadh of Argyll or Donnchadh mac Dubhghaill was a late 12th and early 13th century Scottish noble. He was the son of Dubhghall mac Somhairle, son of Somhairle mac Gille Bhrighde. He is the first of the MacDougall lords of Argyll to take the title de Argadia, and can be regarded as the founder of the successful MacDougall lordship of Argyll. He was also a prominent builder, notable for his construction of Ardchattan Priory and Dunstaffnage Castle.
context_section_description: Donnchadh, like other Scottish magnates of the time such as Uilleam, Earl of Mar, and Fearchar, Earl of Ross, was a prominent religious patron and castle builder. Around 1230, he founded a house for Valliscaulian monks at Loch Etive; this was Ardchattan Priory. The Valliscaulians were a relatively new religious order fashionable in the reign of Alexander II, with other foundations around the same time at Beauly Priory and Pluscarden Abbey. Donnchadh is remembered for his secular buildings too. It was Donnchadh who constructed Dunstaffnage Castle, the site which became the main seat of the MacDougall lords of Argyll. Donnchadh may have been responsible for the huge hallhouse castle at Aros in Mull.
  Donnchadh had several children. The most important of these was his son Eóghan of Argyll, who succeeded to his lordship. It has been alleged, without any authority, that a daughter of Donnchadh named Gill or Egidia married Brian Ua Néill, King of Tír Eógain.
