Sophie Kantorowicz

Hartwig Kantorowicz married Zofia (Sophia) Asch. The date of marriage is not known because no records of the Jewish population registration in Poznan survived. The population records from the second half of the nineteenth century show that Sophia Asch was born in 1815 in Swarzedz, a city known then of drapery, and since the late nineteenth century of the carpentry. Since 1816, her family lived in Poznan at Wroniecka str. No 6. This address is important, because in the last forty years of the nineteenth century there was a Kantorowicz Company. Sophia and Hartwig had 13 children, i.e., one daughter and 12 sons, of whom only seven survived. Sources do not allow the determination of all birth dates and names, with the exception of four brothers. The oldest of them is Max, born March 9, 1843, died April 6, 1904. On the death of his father (Hartwig), Max managed the company together with his two brothers. He married Rosalind Pauly, who was born in Poznan, on January 22, 1854. They had four children, of whom the eldest was Franz Hartwig, born on December 20, 1872 – he received a Doctorate in law, he studied Science and Philosophy at the state Universities in Lausanne, Munich, Berlin and Göttingen.
