Surname origins – Surnames in the Ashkenazi community were in general adopted much later than for the Sephardic Community, for which surnames date to the 10th and 11th centuries. It is not known with certainty where the Kramer ancestor families migrated from. It is likely that they came from central Europe to what was at the time Poland, perhaps by the mid-18th century. The timing of the adoption of surnames in Eastern Europe varied depending on the ruling regime. With respect to Galicia, Wikipedia states, “On 23 July 1787, five years after the Edict of Tolerance, the Holy Roman Emperor Joseph II issued a decree called Das Patent über die Judennamen which compelled the Jews to adopt German surnames”, setting a latest date by which the family surnames would have been adopted.
