Polignac family

Polignac is the name of a French noble family that took its name from the château de Polignac, of which they had been sieurs since Carolingian times.

In 1385, the male line became extinct, but the heiress married Guillaume, sire de Chalancon, who assumed the name and arms of Polignac. Jules de Polignac (1746–1817) became the first Duke of Polignac in 1780.
