McDougal Family History

This notable Scottish surname is a an anglicized form of the Old Gaelic "MacDubhghaill", a patronymic from the male given name Dubhghall, composed of the elements "dubh", black, dark, and "gall", stranger. This was frequently used as a byname for Scandinavians, in particular to distinguish the darker-haired Danes from fair-haired Norwegians. The McDougall clan are descended from one, Dugall, eldest son of Somerled of the Isles, and were described by the late Dr. Alexander Carmichael as "one of the most unobtrusive and honoured families in Scotland".

MacDougall Mull

My McDougalls came from Ireland to the Isle of Mull Scotland the 1700s. I think they came from Donegal.

(Part 1 of 3) The McDougal name has a long history in Scotland, but now DNA and some recorded history says their origin is from the Emerald Island. The McDougal story [dominated by DNA tribal marker R1b-L513, Subgroup B2] can trace their origins to the Finn Valley in Donegal, Ireland from 50 BCE. Perhaps the journey begins with the Clanna Dedad; Deda, son of Sen or Deda Mac Sin. The McDougal surname origin is from Clan Domnaill [DNA Tribe R1b-L513, Subgroup B1] and relations who remain in Ireland take the modern surname (O’)Donnelly, (O’) Donoghue, McDonald and Hughes in Ireland.

(Part 2 of 3) According to research, the Domnaill name is also found in Brittany, France. It is a very old name which appears in the 5th century Roman inscriptions as Dumnovellaunos in Brittany meaning “Deep Valour” equivalent to Irish Domhnaill. But how could this be? Recent discoveries from DNA testing are unlocking the migration patterns of Celtic tribes as late as 800 CE to 1200 CE. The McDougal story begins in pre-history Donegal then moves to north-east Ireland where the family can be traced back to the Dal Riata. An ancestor and many of his kin will then move to Scotland during the Dark Ages.

(Part 3 of 3) Discover their newly found untold story and how forgotten texts bring their story back to life. From the ebook, “The Tribe Within” learn how DNA unfolds this amazing tale and if you look in the right places, how history narrates this evidence. There is another written account of their story, but it is camouflaged in smoke and myth – it will become the tales of King Arthur. Come follow in the footsteps of Deda Mac Sin and visit
