Blackader, Cuthbert (DNB00)
BLACKADER, CUTHBERT (d. 1485), a chieftain of the Scottish border, received his surname and estate from James II in 1452 for his success in repelling the English marauders on the Scottish frontier. By his prowess he earned for himself the title of the 'chieftain of the south.' He and his seven sons who accompanied him on his expeditions were also named, from the darkness of their complexions, the 'Black band of the Blackaders.' When the kingdom was placed in a posture of defence against Edward IV, the Blackaders raised a force of two hundred and seventeen men, and also planted their castle with artillery, and left in it a strong garrison. During the wars of York and Lancaster Cuthbert and his sons took service in England, and fought under the banner of the red rose. In the fatal battle of Bosworth, 22 Aug. 1485, he and three of his sons were slain.
