Ethnic amalgamation, like it or not: Inheritance in early modern Jewish Rome

Roman Jewry was a composite group in the early sixteenth century, including new arrivals from southern Italy, as well as Sicily and the Iberian Peninsula. There were Italians Jews, and Ashkenazim. By the middle of the century, they had amalgamated well. The "out-marriage" rate between the different groups was constantly increasing. One reason for this was the need to unify administrative procedures. This is especially noticeable with respect to laws of inheritance, in which, thanks to the Jewish Rabbinic notaries, the father and son Judah and Isaac Piattelli, it had become standard for a widower to return to his father-in-law one-third of the dowry, irrespective of how long the marriage had lasted. Jews found themselves adopting Christian procedures, yet also modifying them for Jewish use, thus creating unified Jewish procedure, but allowing for continued acculturation, even during the ghetto period.
