بيت جن
In April 1249 he and his wife sold six "casalia" near Acre to the Teutonic Knights. This included two—Seisor and Mergelcolon and Gedin—that he had inherited from his mother, and Beit Jann and Nahf. In 1253 they sold Al-Damun (and several villages in the vicinity) near Acre to the Hospitallers for 12,000 besants. In 1255 they also sold the Hospitallers everything they owned in Acre as well as the "casalia" of Chasteillon and Rout. On this occasion they were accepted into the lay confraternity of the order as "confrater" and "consoror". Some of the money from the sales to the Hospitallers was used to pay the dower of John's brother Hugh's wife, Isabelle de Tenremonde, of the family of the lords of Adelon. She confirmed the payment of part of her dower in an act of 1259.
