Raymond VI, Count of Toulouse was married five or six times:
1. His first wife, Ermessende, Countess of Melgueil, whom he married in 1172, died in 1176 without issue.
2. His second wife was Beatrice of Béziers, sister of Roger II Trencavel; they divorced in 1189 and she was said to have become a Cathar parfaite after the divorce. Raymond and Beatrice had one daughter, Constance of Toulouse, who was married firstly to King Sancho VII of Navarre, and secondly to Pierre-Bermond II of Sauve, lord of Anduze.
3. Raymond then married for a third time, to Bourgogne, daughter of King Amalric II of Jerusalem and his first wife Eschiva of Ibelin, daughter of Baldwin of Ibelin. He divorced her in 1194.
4. In October 1197 at Rouen he married Joan Plantagenet, but she fled from him in 1199 and died in childbirth. Their only surviving child was Raymond VII of Toulouse (1197–1249).
5. His next relationship (marriage, some say) to a Isabelle, daughter of Isaac Comnenus of Cyprus, had ended by 1202.
6. His last wife was Leonor, daughter of King Alfonso II of Aragon and Sancha of Castile.
Isabelle Comnene was born in 1166. She married Count Raimond VI de Toulouse about 11 Jul 1200. The marriage ended in divorce.
They had the following children:

Good information Janice, but I see a few problems.
Wikipedia doesn't actually give the name Isabelle Comnene. In fact, this article and others make the point that her give name is unknown.
Wikipedia doesn't actually say that she married Raymond VI. It says they had a relationship that might have been a marriage.
Wikipedia doesn't actually say that Bertrand was the son of Raymond VI and his Comnena wife / mistress. It doesn't mention him at all.
I responded to your private message on this subject.
Look at Foundation for Medieval Genealogy. It says that Raymond VI married a daughter of Isaac Comnenus. Her name is unknown, so she is called "la Damsel de Chypre". However, this article says that Bertrand was the son of Raymond VI by an unknown mistress.
