After the conquest of Jerusalem in 1099 Fulcher and Baldwin travelled to the city to complete their vow of pilgrimage. When Baldwin became king of Jerusalem in 1100, Fulcher came with him to Jerusalem and continued to act as his chaplain until Baldwin died in 1118. At that time, Fulcher may have been serving as Prior at the Mount of Olives. After 1115 he was the canon of the Church of the Holy Sepulchre, possibly attached to the Canons of the Holy Sepulchre, and was probably responsible for the relics and treasures in the church. Fulcher was a resident of Jerusalem until 1127. After that date, nothing further is known about him. Any details about his death are unknown.
