The members of the family who had served the Grand Ducal House of Mecklenburg left the Residenz Güstrow in 1696 and turned to Lüneburg,[5][17] which was equal to a Free Imperial City.

[28] Since the 17th century Hamburg played a special role in Germany's economic history[29] because thanks to its fortifications [de] it came out of the Thirty Years' War as the wealthiest and most populous of all German cities.

Keeping with the age-old Hanseatic tradition in setting up humanitarian foundations[75] the Jauch maintained a daily soup kitchen for the poor for free (German: Armenspeisung).

Lieutenant general of the Waffen-SS Karl Fischer von Treuenfeld, descendant of Eleonora Maria Jauch (1732–1797), was a close friend of Erich Ludendorff and one of the leading figures of the Beer Hall Putsch in 1923, a failed attempt by Adolf Hitler, to seize power in Germany.

Johann Christian Jauch the Elder quit the service and became burgher of the city of Güstrow, dealing at retail and being a court shoemaker, purveyor to the ducal family.

[5][6] His eldest son Johann Christopher Jauch (1669–1725) had been a stipendiary of the duke[106] and carried out since the end of 1694 the function of a court chaplain (German: Hof- und Schlossprediger).

[22] Carl Jauch (1680–1755), merchant in Lüneburg,[5][116] has been a supporter of the theologian, alchemist and physician Johann Konrad Dippel, by some authors debatably claimed to be the model for Mary Shelley's novel Frankenstein.

[117] Carl Jauch was married to a grandniece of the Lübeck dean August Pfeiffer [de] (1640–1698), who strongly influenced the faith and the thinking of Johann Sebastian Bach.

[46] Thus, they became members of the ruling class, the Hanseatics (Hanseaten) in one of the wealthiest cities of Germany, with whose financial capacity only Vienna could compete because of the local high nobility concentrating there and its wealth.

His great-grandnephew was Ludwig Gümbel [de] (1874–1923), naval architect and significant for the upgrowth of submarines in World War I,[127] cousin of first president of the Federal Republic of Germany Theodor Heuss.

His eldest son Johann Christian Jauch junior (1802–1880) acquired the Manor house Wellingsbüttel,[76] previously domicile of the penultimate Duke of Schleswig-Holstein-Sonderburg-Beck, Friedrich Karl Ludwig, ancestor of the modern-day British royal family.

This allowed US companies to take control of the Guatemalan coffee industry.″ Heinrich Jauch (1894–1945) was the Prosecuting Attorney of the Special Tribunal (German: Sondergericht) Hamburg in the criminal trial against the Soviet agent during the interwar period Jan Valtin and 52 other defendants of whom nine were condemned to death.

The novelist Arnold Zweig read in 1938 in a newspaper in Haifa the mistaken information that Dettmer and others had been executed by a master butcher named Fock who after a couple of months had committed suicide.

[144] Major General Hans Oster (1887–1945), one of the earliest and most determined opponents of Adolf Hitler and Nazism, moving spirit of German resistance from 1938 to 1943, was a first cousin-in-law of Rittmeister (English: captain of the cavalry) Walter Jauch [de] (1888–1976).

Oster and his opposition group including Hans von Dohnányi were supported by Jauch & Hübener,[147] today's German branch of Aon Corporation.

Walter Jauch's co-founder Otto Hübener [de] was arrested 1945 in Hamburg and hanged in late April 1945 without trial, a few days before the end of Nazi Germany.

The Distinguished Service Cross which has been awarded for this action to Commander Captain Frederick Henry Taylor is part of the collection of the National Maritime Museum at Greenwich.

Her son Karol Maurycy Lelewel (1750–1830) married a daughter of the starosta of Babice, niece of the archbishop and metropolitan of the archdiocese of Mogilev Kasper Cieciszowski [pl] (1745–1831).

Nevertheless, it is often argued, with quite some force, that because of the efforts of the Commission of National Education, the Polish language and culture did not disappear into oblivion, during the Partitions of Poland - heavy Russification and Germanisation notwithstanding.

Lieutenant Colonel Jan Pawel Lelewel (1796–1847), was a Polish freedom fighter who unsuccessfully defended 1831 Praga against the Russian invasion and participated on 3 April 1833 in the Frankfurter Wachensturm, the attempt to start a revolution in all German states.

[164] Her granddaughter Aleksandra Franciszka Cieciszowska was married to the Polish minister Jan Paweł Łuszczewski 1784–1795 private secretary of the last King and Grand Duke of the Polish-Lithuanian Commonwealth Stanisław August Poniatowski.

[175] Constance Jauch's granddaughter Anna Cieciszowska was sister-in-law of Magdalena Agnieszka Sapieżyna (1739–1780), daughter of Antoni Benedykt Lubomirski and informal consort of King Stanisław August Poniatowski.

[178] Her grandson was the painter and head of the Nazarene movement Johann Friedrich Overbeck (1789–1869),[86][88] decorated with the Prussian Order Pour le Mérite for Sciences and Arts.

At that time he was painting the large-sized "Christ absconding from the Jews" (1858), a commission from Pius IX, and an allegory on the pope's escape 1848 from Rome in disguise as a regular priest, originally on a ceiling in the Quirinal Palace, later covered by the king, and now hanging in front of the Aula delle Benedizione in the Vatican.

Datum Romae apud S. Petrum die 2 Septembris 1850 Pontificatus Nostri anno quintoThe archaeologist Johannes Adolph Overbeck (1826–1895) was Constance Jauch's grand-grandson.

[86] Her great-granddaughter Cäcilie Lotte Eleonore Overbeck (1856-post 1920), married the anthropologist and ethnologist Emil Ludwig Schmidt (1837–1906), who was personal physician of the hypochondriac "Cannon King" Alfred Krupp.

The great-granddaughter Wilhelmine Friederike Charlotte Overbeck (1829–1908) was wedded to the well known mechanical engineer Franz Reuleaux (1829–1905),[86] chairman of the German panel of judges for the Centennial International Exhibition in Philadelphia 1876.

Wilhelmine Jauch (1809–1893) married Theodor Avé-Lallemant, from his maternal side a descendant of the Huguenot leader in the French Wars of Religion Gaspard II de Coligny (1519–1572).

When I then visited this kindly old gentleman, who passionately loves music and who, as should be obvious to the reader, is quite free from that aversion which many old people have against everything that has been written in recent times, I had a very lengthy and interesting conversation with him.

He bequeathed it to his friend, Avé-Lallemant's father,[193][194] the evening before his death in the Battle of Saalfeld with the words: ″In case that I will not return from the battle.″ [195][196] The Jauch [de] from the Canton of Uri in the Old Swiss Confederacy, are chronicled since 1368.
