Julia's father had fought in Napoleon's Polish Legions in Austria, Italy, Germany, and the Peninsular War. After his service in the Polish army from 1790 and in the army of the Duchy of Warsaw from 1809 to 1814, he entered the ranks of the army of Congress Poland, was promoted to general in 1828, and was awarded a Russian title. Recognising his abilities, Emperor Nicholas I appointed him Deputy Minister of War of Congress Poland and made him an hereditary count in 1829. In the November Uprising of 1830, led by rebelling army cadets, Grand Duke Constantine, Poland's Russian governor, managed to escape, but Julia's father was shot dead by the cadets on a Warsaw street. Her mother died of shock shortly afterwards, and their children were made wards of the Emperor.
