County of Edessa
Alfonso-Jordan (1103–1148) was the son of Raymond IV and his third wife, Elvira of Castile. Although he was born in Tripoli, Alphonso-Jordan was raised in France. In 1147, he joined the Second Crusade, which was launched in response to the loss of the County of Edessa to Turkish forces. Alphonso died, possibly poisoned, in Caesarea, in 1148. He had an illegitimate son, Bertrand of Toulouse, who continued his progress towards Tripoli.
