William or Guillaume Barlais was a Lord of Beirut in the Kingdom of Jerusalem, via his marriage to Isabella of Beirut in 1277 - he was her fourth and final husband. They died childless and she had no children from her previous three marriages to Hugh II of Cyprus, Hamo le Strange and Nicolas l’Aleman - the Lordship of Beirut thus passed to her sister Eschiva of Ibelin and her husband Humphrey of Montfort, Lord of Tyre.
