Context: Dorothea "Dolly" de Ficquelmont (14 October 1804, Saint Petersburg, Russian Empire10 April 1863, Venice, Austrian Empire), born Countess Dorothea von Tiesenhausen ("Daria Fyodorovna" in Russian), was a Russian writer and salonist.  A granddaughter of the Russian war hero General Prince Kutuzov (who distinguished himself in the Napoleonic Wars), she was a Russian aristocrat of German Baltic origin, and later a member of the Austrian nobility as the wife of Count Karl Ludwig von Ficquelmont. Emil Georg von Stauss (often rendered Emil Georg von Stauß, 6 October 1877 in Baiersbronn – 11 December 1942 in Berlin) was a German banker who served as Director-General of the board of the Deutsche Bank. Gerhard Diedrich Jakob von Tiesenhausen (Latvian: "Gerhards fon Tīzenhauzens" ; March 26, 1878 in Tartu † October 26, 1917 in Tiraspol) was a Livonian art nouveau architect.  He was from the Tiesenhausens ancestry, father of Hans-Diedrich von Tiesenhausen. Georg F. von Tiesenhausen (born May 18, 1914) is a retired German-American rocket scientist.  After being brought to the United States in 1953 as part of Operation Paperclip, he was part of Wernher von Braun's team at the U.S. Army, and later, NASA.  He is credited with the first complete design of the Lunar Roving Vehicle and made a variety of other contributions to the space program. Hans-Diedrich von Tiesenhausen (22 February 1913 – 17 August 2000) was a German naval commander during World War II.  He was a recipient of the Knight's Cross of the Iron Cross of Nazi Germany. Count Berend Gregor Ferdinand ("Fiodor Ivanovich" in Russian) von Tiesenhausen (June 1, 1782, Reval – December 2, 1805, at the Battle of Austerlitz) was a Russian noble and military officer of German Baltic origin. The Battle of Varja took place on November 7, 1700 close to at the villages of Varja and Aa, in the Swedish Empire during the Estonian campaign of the first year in the Great Northern War.  A Swedish force consisting of 800 men under the command of generals Georg Reinhold Patkul and Hans Henrik von Tiesenhausen were sent out from Rakvere to secure the road at which the main army under Charles XII of Sweden were going in order to relief the city of Narva which had been besieged by the Russians for a while.  At the villages of Varja and Aa they surprised a Russian force of 2,000 men from Boris Sheremetev's detachment gathering supplies for their army at Narva.  The Russians were caught completely off guard and subsequently took cover within the houses to avoid the Swedish onslaught, these were however, soon put on fire by the Swedes, an action resulting in 1,500 Russians killed, wounded or captured to about 200 Swedes with only 500 Russians who managed to escape.  Later during the day, as the Swedes were looting the Russian supplies, a larger force of 3,000 men under Sheremetev himself, arrived and in turn surprised the Swedes who were driven off with a loss of 80 men among them, the Swedish commander Georg Reinhold Patkul who was captured during the retreat.  The Russians here received important information about the approach of the Swedish main army under Charles, who arrived at the two villages about two weeks later.  Sheremetev would later face the Swedish vanguard at Pühhajoggi, however after initial skirmishes he was soon driven off leading to the battle of Narva where the Russian main army saw itself decisively defeated by the Swedish army. Count Johann Georg von Browne (or Johann Georg von Browne-Camus; 20 September 1767 – January 1827) was an officer in the Russian army, and settled in Vienna where he was a patron of Ludwig van Beethoven during the composer's early career.
