There maybe some connection to names such as de Barr, des Barres, etc. Family legend for my own connection claims to be Scottish (Gaelic), which may be totally spurious as there seems very few persons with names even similar the closest being Dunbar which may mean fort of the bar or reference to a high fort, gaelic forts tending to set up on hills according to my poor scholarship.

Originally from the Irish monk Barr-fhionn* who around the year 593 left Dalriada as a missionary to the Britons living in southwest Scotland (formally Carrick, now South Ayrshire).  Travelling along the river Stinchar he had his cell in what is the present day village of Barr.  He left the area, probably at the time of the Angle invasion under Ethelfrith king of the Angles (603)  He sailed for the island now called Barra in his name.  The church of St. Barr was completed there in 620 A.D.
