The granddaughter of The Very Reverend and vice-dean of the cathedral of Bardowick Johann Christian Jauch (1702–1788), Margaretha Eleonora Ludovica Jauch (1772–1805) was married twice.
Son from her first marriage with the merchant Johann Carl Deetz was Colonel Albert Deetz (1772–1852) who became in 1847 town major of Wittenberg.
Later he became head of the central office of the Prussian Minister of War.
1848–1854 he was town major of Frankfurt, member of the Frankfurt Parliament and one of the thirtytwo members of the Emperor Deputation, chosen by the National Assembly, which offered on 3 April 1849 the Imperial Crown of Germany to Frederick William IV of Prussia.

In Frankfurt I lodged in the L'hotel de Russie ... I became acquainted with an endearing 'ruin of the parliament', the town commandant of Frankfurt, the Prussian colonel von Deetz.
This good old man told me stories from a Thousand and One Nights and forgot totally, that he was a Prussian colonel.

— Georg Weerth, letter to Friedrich Engels 1852
Otto von Bismarck was at that time Prussian envoj to the Federal Convention in Frankfurt.
His relationship to Albert Deetz as town commandant of Frankfurt and member of the Convention was distressed, because Deetz strictly refused to cooperate with him.
Bismarck reported to Berlin:
The conspirator Deetz always causes inconvenience for me.

— Otto von Bismarck
