The lords of the castle at Lusignan became counts of La Marche in the 12th century. They added the county of Angoulême to their holdings in 1220, when Hugh X of Lusignan married Isabella of Angoulême, daughter of Count Aymer of Angoulême and widow of John, King of England. These acquisitions produced complicated titles. For example, Hugh XI of Lusignan was Hugh VI of La Marche and Hugh II of Angoulême.
