Who was Sir Lancelot married to?

In the medieval romance Lanzelet, Lancelot (Lanzelet) marries four different women, one after the other, and then settles down permanently with the third who was named Iblis. This is the only account in which Lancelot is married.

In most medieval romances that get into Lancelot's love life, Lancelot was Queen Guenevere's lover and had no romantic interest in any other woman.
