Joachim Daniel Jauch's daughter Constance Jauch (1722–1802) married Heinrich Lölhöffel von Löwensprung (1705–1763), privy councillor (German: Hofrat) and physician to the King Augustus III of Poland.
After the death of her father she erected 1755 by Ephraim Schröger the Lelewel Palace – her polonized name – in the Miodowa.
Regardless the early death of her husband in 1763 she enabled a splendid career for her children.

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 (1745–1831).
Karol Mauricy Lelewel was a Royal Polish captain, reached the indygenat, the naturalisation as a Polish noble, and became a member of the general sejm.
 1789 he became appointed as cup-bearer of the Grand Duchy of Lithuania (Polish: Podczaszy wielki litewski), a title possessed prior by Stanisław August Poniatowski before he was elected as the last king and grand duke of the Polish-Lithuanian Commonwealth.

Karol Mauricy was from 1778 until 1794 the lawyer and treasurer of the Commission of National Education, which was because of its vast authority and autonomy considered the first Ministry of Education in European history.
Lelwel was also centrally linked to another important achievement of the Polish Enlightenment, the Constitution of May 3, 1791.

After 1789 during the Sejm Wielki the reformers had to sacrifice many of their privileges in order to gain support for the Constitution of May the 3rd.
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.

Constance Jauch's grandsons were Joachim, Prot und Jan Pawel Lelewel.

Joachim Lelewel (1786–1861) became Poland's most famous historian.
He was a rebel, creator of Poland's unofficial motto "For our freedom and yours", member of Poland's Provisional Government 1830, was jointly with Karl Marx and Friedrich Engels founder and vice-president of the Democratic Society for the Unification and Brotherhood of all People in Brussels (Demokratische Gesellschaft zur Einigung und Verbrüderung aller Völker (Brüssel)).
The anarchist Michail Bakunin was strongly influenced by him.
He was a friend of Gilbert du Motier, marquis de Lafayette, who had given shelter to him in his manor Lagrange, where he was later arrested and then expelled from France.
The 29 May is Lelewel's memorial day in the Jewish almanc for his commitment for the Jewish emancipation.

Prot Lelewel (1790–1884) served as a captain during the French invasion of Russia, participated 1812 in the Battle of Berezina and 1813 in the Battle of Leipzig and was decorated as a chevalier of the Légion d'honneur and with the silver medal of the Virtuti Militari.
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.
1816–1826 he modernized Zamość Fortress, after his escape from Poland and Germany he became 1837–1947 head engineer of the Canton of Bern.

Constance Jauch's daughter Teresa Lelewelowna (1752–1814) married Adam Józef Cieciszowski (1743–1783), brother of the archbishop and metropolitan Kasper Cieciszowski.
