Career
Thierry was probably a French knight who came with the Third Crusade to the Holy Land in 1190. Their origin is unknown. It was among the retinue of Count Henry II of Champagne, who ascended as King of Jerusalem in 1192.
This allowed him to marry Melisende, the heiress of the Lordship of Arsuf. With Melisande had seven daughters, who were killed before him. Thus died without heirs in 1207.
