According to
Fulcher of Chartres, Baldwin arranged for Cecilia to be married to
Roger of Salerno. Roger and Cecilia married in 1113, soon after he became prince-regent of
Antioch. Together with the marriage of Baldwin's daughter
Alice of Antioch to
Bohemond II, Prince of Antioch, the women of the
Rethel dynasty were among the most powerful in the Holy Land. She was granted lands in
Cilicia some time before 1126, which may have facilitated the marriage of Cecilia's sister Béatrice to
Leo I, Prince of Armenia. According to Rüdt-Collenberg,
Cæcilia dominia Tarsi et soror regis Balduini II donated property to the church of
St Marie, Josaphat by charter dated 1126, with the agreement of Bohemond II. Cecilia held a lordship in Cilicia at the start of the reign of Bohemond II and was known as the lady of
Tarsus (probably self-anointed in a charter). She was a major Antiochene landholder and is believed to have helped organize Antioch's defenses in 1119, when, during the
Battle of Ager Sanguinis, her husband Roger was killed. Cecilia was not considered as a possible regent nor did she play a role in picking Roger's successor. Cecilia and Roger had no children. It is not known what her activities were after her husband's death. ==See also==
