Clan Barclay
"Aut Agere Aut Mori" (Either Action or Death)

Clan Barclay is a lowland Scottish clan. Since the eighteenth century, Barclay historians, noted for their low level in medieval scholarship, have assumed the Scottish family Barclay (de Berchelai) is a branch of one of the two Anglo-Norman families of de Berkeley of Berkeley in Gloucestershire, without any evidence which would link the Scottish and English families.
A more plausible theory of the Barclay origin, put forth by the historian G.W.S. Barrow, points to the small village of Berkley in Somerset (in 1086 Berchelei).
