Juliana Grenier (French: Julianne; died 1213×16) was the lady of Caesarea, which she inherited from her brother, Walter II, upon his death between 1189 and 1191.
In 1183, Juliana and Guy, who were apparently with the royal court in Jerusalem at the time, consented to her brother's sale of the casale of Galilaea, near Caesarea, to the Order of the Hospital for 5,000 bezants.
[1] In 1206, she, with the consent of her husband and eldest son, granted a house and some land in Acre to the Teutonic Knights.
In 1207, with her husband's consent, she made a donation to the Order of the Hospital of a house and three carucates at Capharlet and the casalia (extended casale) of Pharaon and Seingibis (Khirbat Nisf Jubail) for the salvation of her parents' souls.
[1] There is also a later record, attesting to their monetary needs, that some time before 1243 a lady of Caesarea had sold land to the Teutonic Knights.
