Count of La Marche in the context of William III, Duke of Aquitaine

Hugh X de Lusignan or Hugh V of La Marche (c. 1183 – c. 5 June 1249, Angoulême) was Seigneur de Lusignan and Count of La Marche in November 1219 and was Count of Angoulême by marriage. He was the son of Hugh IX.

Louis I, called the Lame (1279 – 1341) was a French prince du sang, Count of Clermont-en-Beauvaisis and La Marche and the first Duke of Bourbon, as well as briefly the titular King of Thessalonica from 1320 to 1321.

Hugh IX "le Brun" of Lusignan (1163/1168 – 5 November 1219) was the grandson of Hugh VIII. His father, Hugh Brunus (b. c. 1141), was the co-seigneur of Lusignan from 1164, marrying a woman named Orengarde before 1162 or about 1167 and dying in 1169. Hugh IX became seigneur of Lusignan in 1172, seigneur of Couhé and Chateau-Larcher in the 1190s, and Count of La Marche (as Hugh IV) on his grandfather's death. (c. 1165–1171) Hugh IX died on the Fifth Crusade at the siege of Damietta on 5 November 1219.

Hugh IX is mentioned under the pseudonym Maracdes ("Emerald") in two poems by the troubadour Gaucelm Faidit, according to the Occitan razós to these poems.
