Comborn
The viscounts of Comborn were one of the oldest feudal dynasties of Bas-Limousin, seated at the castle of Comborn near Orgnac. The first identified lord, Archambaud, held the title in 958, and his son Archambaud I, called the Butcher and later Rotten Leg, became viscount of Comborn in 962 and of Turenne around 976.
An elder line took Turenne, a younger son received Ventadour in the eleventh century, and the marriage of Archambaud the Bearded to the heiress of Limoges carried that viscounty to his elder son. Guichard V, lord of Treignac and Chamberet, bought the viscounty of Comborn in 1374 and died at Agincourt in 1415.
His last heirs sold Comborn in 1508 and 1509. It passed through a Comborn daughter to the viscounts of Pompadour.
