A Benno Markiewitz is listed in the 1910 Kattowitz address book as a businessman of Grundmannstrasse 36; this is consistent with the births of Johanna (1895) and Siegfried (1896) close to Kattowitz. He is absent from the 1914 Kattowitz address book.

Ancestry.com records a Benno Markiewitz in the Breslau address books from 1911 to 1918.

A Benno Markiewitz first appears in the Berlin address books in 1919, and the entries continue until 1942. The later Berlin address book lists him at Sybelstrasse 68. A Baruch Markiewitz is listed in 1939 census of Berlin at Sybelstrasse 68, but the source for this does not list a Benno Markiewitz; it is likely that they are the same person. According to the census, Baruch was born on 29/10/1866 in Ostrow and shared the address with a Marie Markiewitz née Krakauer born in 1868; thier marriage certificate shows that they married in Berlin 1918.



The 1941 Belin address book has separate entries for "Markiewiez Baruch" and "Markiewitz Benno", both at the same address. This may be the result of the compiler accessing information about the same person from two sources, or it may hint at Benno and Baruch being different people; based on other evidence cited on this page I believe it more likely that they are the same person.

Benno's first wife, Hedwig, is listed under her married name in the Berlin address books from 1917 to 1927 at a separate address from Benno; the 1927 entry also gives her maiden name and erroneously describes her as a widow.

AF, a descendant of Benno (Baruch) Markiewitz, tells me that his father knew Benno as Baruch, and that both Benno and Hedwig lived to Berlin, albeit separately. Benno was buried in Weisensee Cemetery next to his second wife Marie.
