The hop business was by no means easy as there was keen competition. In addition the hops had to be sulphurized i.e. exposed to sulphur fumes to prevent spoilage. The police opposed this practice on account of the fire hazard. It was also feared that sulphurizing was dangerous to the health of the beer drinker. When the police learned of such sulphurizing, the hops were confiscated and destroyed. This meant a serious loss.

Gradually the City Councils of more cities permitted the settlement of Jews within their city. Such permits always required the payment of a considerable tax.

On April 28, 1847 Feist (Philipp) Tuchmann moved to Dessau where he had many friends. In 1852 Loeb Hopf, husband of Marx Tuchmann's oldest daughter Gella, moved to Nuremberg and became one of the first six Jews who returned to Nuremberg after the expulsion of 1499. Salomon Tuchmann moved to Fuerth during April 1848 and to Nuremberg between 1865 and 1867.

The restrictions regarding residence were not removed until Bavaria passed a law on November 10, 1861. Equal rights were not acquired by the Bavarian Jews until a federal Law was passed on July 3, 1869 and enacted in Bavaria on April 22,1872.

None of the eight children of Marx Tuchmann remained in Markt Uehlfeld. Four moved to Nuremberg, the rest to Bamberg, Dessau, Fuerth and Burgkundstadt.

Marx Tuchmann died on February 24, 1850 and is buried in the Jewish cemetery of Markt Uehlfeld.
