(Part 1 of 3) The Jester name has a long history in British Isles, but now DNA and some recorded history says their origin is from the Emerald Island. The Jester 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 Jester surname origin is from Clan Domnaill [DNA Tribe R1b-L513, Subgroup B1] and relations who remain in Ireland take the modern surname (O’)Donnelly, McDonald and Donohue 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 Jester story begins in pre-history Ireland then moves to Wales where the family can be traced back to their Welsh tribe Cydifor Fawr. An ancestor and many of his kin will then move to Brittany, France during the Dark Ages.
