Before Jacob · compiled genealogy
Abraham Jacob Reichenbach and Therese Frank
Paul’s 1935–36 research and the ancestral chart point to Abraham Jacob Reichenbach and Jette or Therese Frank as Jacob’s parents, married around 1810. The names are preserved as a probable earlier generation; no civil or synagogue record in the collection yet proves the link.
Helene’s line · ancestral chart
Heinemann and Betty Krömer
The Ahnentafel names Helene Heinemann’s parents as Heinemann (8 July 1796–2 December 1863) and Betty Krömer (10 June 1794–25 December 1852). The chart is compiled genealogy rather than a civil register, but the names and dates are preserved as recorded.
Goldine’s line · Schwerin and Berlin
Louis Marcuse and Johanna Cohn
The ancestral chart names Goldine’s parents as the merchant Louis Marcuse (6 October 1813–16 April 1884) and Johanna Cohn (19 March 1817–22 April 1894), both rooted in Schwerin and later recorded in Berlin. It carries the Marcuse line one generation farther to Mordechai Markus Lewin Marcuse (1777–1852).
Margarete’s line · Halle and Hettstedt
Philipp Liebenthal and Jenny Schottländer
A printed 1887 engagement announcement names Margarete’s parents: Philipp Liebenthal, a merchant of Halle, and Jenny Schottländer, the only daughter of L. Schottländer and his wife née Salzmann of Hettstedt. Identified family portraits preserve Philipp and Jenny together.
Jeanette’s line · Göttingen
Abraham Rosenbaum and Bertha Grunsfeld
Jeanette and Gustav’s 1883 civil marriage record names Jeanette’s parents as the merchant Abraham Rosenbaum and Bertha née Grunsfeld, both resident in Göttingen. This adds a documented maternal generation to the Wernigerode branch.
Ruth’s marriages · civil records and wedding verse
Pützrath, Rothschild and Spiegel
Ruth married Dr. Martin Pützrath in 1930; the marriage ended in divorce in 1932. She married Albert Rothschild on 3 August 1933. Dolf’s wedding song names Albert’s father as Max Rothschild and warmly includes an unnamed mother. Ruth later used the married name Spiegel; that later marriage record has not yet been found.
Jacob/Jakob branch · family testimony
Anna Reichenbach, Adolph/Adolf Jacob, Herbert and Vernon
Family testimony reports that Paul had a sister Anna who married a man named Jacob/Jakob, lived in Frankfurt, and had a son Dolf/Adolf who reached New York. Herbert Jacob's obituary independently documents Herbert as the son of Adolph and Marga and brother of Vernon. The branch is shown in the tree as a live family lead, but Anna's Halberstadt birth record, her Jacob/Jakob marriage, and Adolph's parentage have not yet been found.
Collateral kin · exact branch unresolved
Paula Reichenbach, Georg Wollenberg and Hans
Paula Reichenbach married Georg Wollenberg in 1903; their son Hans was born at Eisenach on 3 June 1907. Paul called Georg a cousin by marriage. Dolf’s ‘Uncle Georg’ is most plausibly this Georg, but Paula’s parents—and therefore the exact connector to the principal tree—remain unknown. The original 1942 transport list records Paula and Hans together at Westendorf 15.
Another Reichenbach household · exact branch unresolved
Moritz, Miriam Mathilde and their child Paul
The cemetery register and adjoining graves establish the Quedlinburg household of Moritz Reichenbach—Moshe HaLevi—and Miriam Mathilde née Loewenthal. The register names their child Paul, who died in 1904. Their relationship to Jacob’s descendants remains open.
