The original will of Mahara was made in January 1143. A decade later, in November 1153, Mahara's nephew requested a copy, and that is the version that exists here. The document is written in Judeo-Arabic.
DESCRIPTION FROM THE PRINCETON GENIZA PROJECT:
Copy of a will of Mahara bat Avraham ha-Kohen that had been made and dated in Alexandria in January 1143, issued at the request of her nephew, to whom his dying aunt had willed 10 dinars and also money to other family members. She stipulated that any money remaining after the payment of the burial expenses and of the sums bequeathed by her to relatives (with the exclusion of her son) should be given to the poor, but charged her executor with this task, not the officials of the community chest, while the court was to choose the charities worthy of consideration. Dated in November 1153. (Information from Mediterranean Society, II, pp. 111, 545)
