BOREK:
Town in the district of Koschmin, province of Posen, Germany. So long as the city was under the domination of the Church, Jews were not permitted to settle there; but they were granted this right by the Polish proprietor Von Nyeswasdowski when it came under his administration during the middle of the eighteenth century. In the year 1793, when Prussia took possession of Borek, there were already 448 Jews there, who maintained a synagogue—which was replaced by a new one in 1857—as well as a cemetery. At the present time (1902) the Jewish population of Borek numbers only 150 souls, out of a total population of 2,000.
Borek is the birthplace of Elias Guttmacher, known by the name "Grätzer Raw."
