Friedrich Wilhelm Rembert von Berg

Berg along with his siblings spent their childhood in the Sagnitz castle and were home educated by the young Friedrich Georg Wilhelm Struve.

Originally not seeking a military career as a family tradition, Berg enrolled into the Philosophy faculty of Imperial University of Dorpat in 1810.

He entered the army as a Fahnenjunker and was enlisted into the 6th Libau Infantry Regiment which was stationed at the north-western part of Russia to defend against Napoleon.

After Napoleon was pushed out of Russia, Berg was transferred to a partisan unit under the commands of Baron von Tettenborn and Pavel Kutuzov and took part in actions in Germany including the Battle of Leipzig.

In 1839, after a long relationship with the Baroness de Sassè, he married[10] a rich Milanese aristocrat Leopoldina Cicogna-Mozzoni (1786–1874), the widow of the Italian politician Alessandro Annoni, with whom he had no children.

However, after his brother Gustav's death in 1861, Friedrich adopted his orphaned nephews and brought them under his care: Since his marriage was childless, his Austrian and Finnish comital titles were inherited by his nephews/adoptive children.
