According to this, she is said to have poisoned her husband with fresh cherry cake out of love for Napoleon and was then condemned from afar to always wear a chain and a rope around her neck.

Here she married on October 10, 1802, Count Ferdinand Hans Ludolph von Kielmannsegge (born February 14, 1777, † August 19, 1856), who served as the Hanoverian envoy in Saxony was active.

Due to the paternal inheritance of the above-mentioned properties in Upper Lusatia, Auguste Charlotte von Kielmannsegge was the landlady and judge as well as church patroness of the small Saxon town of Neusalza and the neighboring village of Spremberg, today Neusalza-Spremberg.

Over time, the spying became conspicuous there and warnings were given about "this great hulking woman from Kielmannsegge", who often instigated intrigues in order to obtain information about Napoleon's opponents.

From Saxon government files it emerges that Countess Kielmannsegge was under the surveillance of the authorities for a long time and was considered a politically dangerous person.

A private trip to contact the Napoleon family was prevented in 1818 at the instigation of the Saxon ambassador in Vienna, Count Friedrich Albrecht von der Schulenburg.

The "Dresdner Findling", a later wage clerk by the name of Ernst Graf, had given himself the name Napoleon Bonaparte and tried to prove his alleged ancestry through a brochure and memos.

In 1829, Auguste Charlotte von Kielmannsegge acquired the estate of Oberpöring and Niederpöring and on April 20, 1830, together with her daughter Natalie, she was accepted into the count class of the Bavarian aristocratic registers.
