BLAIR Family History

Recorded as de Blare, Blare, Blayr, and the more popular Blair, this famous Scottish surname is locational. It probably originates from Blair House in Ayrshire, although the area of Mount Blair in the former county of Forfarshire in the far North East is also a possibility, as are the various Blair villages in Perthshire and Dunfermline. In all cases the derivation is from the pre 9th century Gaelic word "blar", meaning a field or plain but more specifically a battlefield! The surname is well recorded in the records of Scotland from the early 13th century with examples including Brice de Blar and Alexander del Blair who witnessed an agreement between the burgh of Irvine and Brice de Eglunstone in 1205...

(Part 1 of 3) The Blair name can be found in Scotland, but its origin according to DNA is from the north-west coast of the Emerald Island. The Blair story [dominated by DNA tribal marker R1b-L513, Subgroup A1] 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 Blair surname origin is from a Northern Ui Neill [R1b-L513] tribe. The Cenél Eoghan and the tribes of Donegal conquered much of Ulster (Derry and Tyrone).

(Part 2 of 3) Cenél Eoghan will expand across northern Ireland with their cousins Cenél Conaill and the Northern Ui Neill between 500-800 BCE. The clans of Finn Valley have the same DNA as people from Gwynedd in Brittany. 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 Blair story begins in pre-history Ireland then moves to Scotland as they form part of the Dalriada. Descendants of their tribe will then travel to Brittany, France during the Dark Ages.
