GRANT Family History

Recorded as Grant, Grand, Le Grand, and Legrand, this is an Anglo-Scottish, Belgian and French surname. It has two possible origins. The first is early French, and introduced into the British Isles at the time of the famous Norman Conquest of 1066. As such it was a nickname derived from the word "graunt", meaning tall or perhaps large, and ultimately from the Latin "grandis". In medieval times it enjoyed much the same family status as in the modern senior or junior, and was used to distinguish between people of the same family name, but of different generations. A second origination is pre 7th century Old English...

(Part 1 of 4) The Grant name has a long history in British Isles, but now DNA and some recorded history says their origin is from the Emerald Island. The Grant 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 Grant 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 4) 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 Grant 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.

(Part 3 of 4) Robert de Grantmesnil (family name of Grant) is born in 990 and living in Calvadoes, Normandy. His father was Gavase le Breton born in 960 from Dol, Brittany. William the Conqueror’s army consists of many Bretons. Robert’s descendant will join the Normans and invade England in 1066. 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.

Part 4 of 4) 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
