Altheides
Altheides( 1193–1262) was a Cypriot philosopher, primarily known from sayings attributed to him in the works of others.
Little is known about the wandering philosopher known as Altheides of Cyprus, and little of his work remains available to modern scholars.
His parents were Greek merchants living on the island under the rule of Guy of Lusignan.
He was born a year before Guy's death, in 1193.
At some point in his late teens he left Cyprus as a seaman on a Moorish trading vessel.

He died unmarried and childless, ending the senior male line of the House of Lusignan( a junior male line through Guy's great- uncle, William de Valence, continued until the death of that man's son, Aymer, in 1324).
In spite of this junior male line, Guy was succeeded by his sister Yolande I& I& I de Lusignan, except in Angoulême, since after his death it was sold to the French Crown by his sisters Jeanne and Isabelle.

Guy XVI, Count of Laval, Mayenne (1 October 1476 – 20 May 1531) was a member of the House of Laval.
He was christened Nicolas, but upon inheriting the title, he took the required name of Guy, as his predecessors had done.

Hugh II of Châtillon( died 1307), son of Guy III, Count of Saint- Pol, and Matilda of Brabant, was count of St Pol 1289 – 1292 and count of Blois 1292 – 1307.

Hugh III of Cyprus
Hugh III of Cyprus (1235 – 24 March 1284), born Hugues de Poitiers, later Hugues de Lusignan
(he adopted his mother's surname "de Lusignan" in 1267), called the Great, was the King of Cyprus from 1267 and King of Jerusalem from 1268 (as Hugh I of Jerusalem).
He was the son of Henry of Antioch and Isabelle de Lusignan, the daughter of king Hugh I of Cyprus.
He was a grandson of Bohemund IV of Antioch and thus a descendant of Robert Guiscard.
From 1261 he served as Regent for Hugh II of Cyprus in Cyprus, as the "Haute Cour" of Cyprus considered him, as a male, a better regent than his mother Isabella.
She was, however, accepted as the Regent of Jerusalem in 1263.
She died in 1264, and Hugh became the acting regent of the Kingdom of Jerusalem as well as Cyprus.
The regency was contested by his first cousin, Hugh of Brienne, who was the son of Mary of Cyprus, the eldest daughter of Hugh I and hence the senior heir to Cyprus, and heir to Jerusalem after Hugh II.
However, the "Haute Cour of Jerusalem" declared Hugh of Antioch the next regent, as successor to Isabella in proximity of blood.
Hugh II died in 1267 without heirs.
As Hugh of Brienne did not advance his claim on the throne, Hugh of Antioch succeeded as uncontested King of Cyprus on 5 December and was crowned at Santa Sophia, in Nicosia, on 24 December.
He claimed the Kingdom of Jerusalem as well in 1267 or 1268 upon the execution of Conradin.
However, the throne of Jerusalem was also claimed by Mary of Antioch by proximity of blood to Conradin.
The "Haute Cour of Jerusalem" rejected her claim and Hugh was crowned King of Jerusalem at Tyre on 24 September 1269.
Hugh and his descendants, the Kings of Cyprus, assumed his mother's surname of Lusignan in 1267, having inherited Cyprus through that family, thus establishing the Second House of Lusignan.
Hugh disliked dealing with the various factions in the Kingdom of Jerusalem, and left for Cyprus in 1276 in disgust at their defiance of his authority.
The next year, his bailiff, Balian of Ibelin, Lord of Arsuf, was ejected by Roger of Sanseverino, the bailiff of Charles of Anjou, who had purchased the claim of Mary of Antioch.
The kingdom remained under Angevin control for the rest of Hugh's reign.
It is supposed that Thomas Aquinas' work "On Kingship" was written for Hugh III.
He was buried at Santa Sophia, in Nicosia.
