Before Jacob · compiled genealogy
Abraham Jacob Reichenbach and Jette Therese Frank
The Simonis Ahnentafel places Abraham Jacob Reichenbach and Jette Therese Frank as Jacob’s probable parents. Its additional handwritten line after Abraham Jacob is best read as ‘Leiser,’ but that reading remains provisional; it gives his occupation as Handelsmann and leaves his dates blank. The adjoining entry records Jette Therese Frank as born in 1788 and dead at Halberstadt on 17 January 1861. An unsigned 1936 draft or copy in Simonis’s file asks the Halberstadt archive about this couple and a marriage around 1810. The compiled chart and inquiry guide the search, but no civil or synagogue record in the collection yet proves the parentage or marriage.
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.
Anna Jacob’s family · 1931 death notice
Anna and Julius Jacob, Adolf, Herbert and Vernon
A contemporary death notice identifies Anna Jacob, née Reichenbach, her husband Julius and their son Adolf in Frankfurt, while naming Paul, Max, Else and Ernst Reichenbach among the mourners. It places Anna in this close family generation, though it does not name her parents. Anna and Paul each named a son Adolf, and family memory understands both choices as honoring their much-loved father, Adolf Reichenbach. Else Sernau may be the relative remembered as ‘Liesl,’ but no record yet confirms that identification. Herbert Jacob’s obituary names Herbert as the son of Adolph and Marga, the younger brother of Vernon and the father of Andrew. Andy Jacob confirmed those relationships in August 2026 and reported that Vernon is living. It is not yet known whether that later Adolph was Anna and Julius’s son.
Three siblings · three civil birth acts
Paula Reichenbach, Georg Wollenberg and Hans
Three Halberstadt birth acts now confirm the siblings named on the 1945 tracing card. Paula’s 1877 act names Ludwig Reichenbach and Lina née Asch at Hoheweg 24; Antonie’s 1879 act records the same household and writes their mother’s name as Pauline. Curt’s 1889 act names Ludwig and Pauline at Hoherweg 47. Paula married Georg Wollenberg in 1903; their son Hans was born at Eisenach on 3 June 1907. Georg later reported Ludwig’s death at Lindenweg 42 on 7 May 1920, giving his own address as Wollstraße 11. Dolf’s ‘Uncle Georg’ is most plausibly this Georg, though the poem does not give his surname. 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.
