Question: What was the family of Joachim II Hector, former Elector of the town where the river of Finow is located?

full_context: Document 1: East Prussia: Although Brandenburg was a part of the Holy Roman Empire, the Prussian lands were not within the Holy Roman Empire and were with the administration by the Teutonic Order grandmasters under jurisdiction of the Emperor. In return for supporting Emperor Leopold I in the War of the Spanish Succession, Elector Frederick III was allowed to crown himself "King in Prussia" in 1701. The new kingdom ruled by the Hohenzollern dynasty became known as the Kingdom of Prussia. The designation "Kingdom of Prussia" was gradually applied to the various lands of Brandenburg-Prussia. To differentiate from the larger entity, the former Duchy of Prussia became known as Altpreußen ("Old Prussia"), the province of Prussia, or "East Prussia".
Document 2: Fürth: A canal between Bamberg and Nuremberg started operation in 1843. There was a port at Poppenreuth. A new canal with a port in Fürth, the Rhine-Main-Danube Canal, was completed in 1992, creating a navigable connection from the Rhine delta in Rotterdam to the Danube Delta on the Black Sea.
Document 3: Finow: Finow is a river of Brandenburg, Germany. Originally, it flowed into the Oder near Oderberg, but since the creation of the Finow Canal in the 17th century, it flows into this canal near Finowfurt.
Document 4: Rhine: The other third of the water flows through the Pannerdens Kanaal and redistributes in the IJssel and Nederrijn. The IJssel branch carries one ninth of the water flow of the Rhine north into the IJsselmeer (a former bay), while the Nederrijn carries approximately two ninths of the flow west along a route parallel to the Waal. However, at Wijk bij Duurstede, the Nederrijn changes its name and becomes the Lek. It flows farther west, to rejoin the Noord River into the Nieuwe Maas and to the North Sea.
Document 5: Rhine–Main–Danube Canal: The Rhine–Main–Danube Canal (German: "Rhein-Main-Donau-Kanal"; also called Main-Danube Canal, RMD Canal or Europa Canal), in Bavaria, Germany, connects the Main and the Danube rivers across the European Watershed, running from Bamberg via Nuremberg to Kelheim. The canal connects the North Sea and Atlantic Ocean to the Black Sea, providing a navigable artery between the Rhine delta (at Rotterdam in the Netherlands), and the Danube Delta in south-eastern Romania and south-western Ukraine (or Constanța, through the Danube–Black Sea Canal). The present canal was completed in 1992 and is long.
Document 6: Schwärze: Schwärze is a river of Brandenburg, Germany. It flows into the Finow Canal, which discharges into the Oder, in Eberswalde.
Document 7: Kleinmachnow: Kleinmachnow arose at the former "Bäke" creek, today replaced by the Teltow Canal built in 1906. "Parvo Machenow" was first mentioned in the 1375 land registry ("Landbuch") of Emperor Charles IV, then also Brandenburg Elector. In medieval times the ford was controlled by a castle, recently held by the Hake noble family. Together with the canal the Kleinmachnow lock was erected, soon becoming a landmark.
Document 8: Albert Wolfgang, Count of Hohenlohe-Langenburg: He was head of the House of Hohenlohe-Langenburg and introduced primogeniture in Langenburg in 1699. This meant the oldest son would inherit the entire county, and younger sons would only inherit if the oldest were to die childless. From then on, younger sons would mostly embark on military careers, for example, in the imperial army, or in friendly nations.
Document 9: Huguenots: Frederick William, Elector of Brandenburg, invited Huguenots to settle in his realms, and a number of their descendants rose to positions of prominence in Prussia. Several prominent German military, cultural, and political figures were ethnic Huguenot, including poet Theodor Fontane, General Hermann von François, the hero of the First World War Battle of Tannenberg, Luftwaffe General and fighter ace Adolf Galland, Luftwaffe flying ace Hans-Joachim Marseille, and famed U-boat captain Lothar von Arnauld de la Perière. The last Prime Minister of the (East) German Democratic Republic, Lothar de Maizière, is also a descendant of a Huguenot family, as is the German Federal Minister of the Interior, Thomas de Maizière.
Document 10: Joachim II Hector, Elector of Brandenburg: Joachim II ( or "Hektor"; 13 January 1505 – 3 January 1571) was a Prince-elector of the Margraviate of Brandenburg (1535–1571), the sixth member of the House of Hohenzollern. Joachim II was the eldest son of Joachim I Nestor, Elector of Brandenburg and his wife Elizabeth of Denmark, Norway, and Sweden. He received the cognomen Hector after the Trojan prince and warrior for his qualities and prowess.
Document 11: Joachim, 6th Prince Murat: Joachim Murat, 6th Prince Murat (Paris, Île-de-France, France, August 6, 1885 – Paris, Île-de-France, France May 11, 1938), was a member of the Bonaparte-Murat family.
Document 12: Prince Johann Georg of Hohenzollern: Prince Johann Georg was the sixth child of Frederick, Prince of Hohenzollern (Heiligendamm 30 August 1891 – Krauchenwies 6 February 1965) and his wife Princess Margarete Karola of Saxony (Dresden 24 January 1900 – Freiburg im Breisgau 16 October 1962).
Document 13: Rhine: A regulation of the Rhine was called for, with an upper canal near Diepoldsau and a lower canal at Fußach, in order to counteract the constant flooding and strong sedimentation in the western Rhine Delta. The Dornbirner Ach had to be diverted, too, and it now flows parallel to the canalized Rhine into the lake. Its water has a darker color than the Rhine; the latter's lighter suspended load comes from higher up the mountains. It is expected that the continuous input of sediment into the lake will silt up the lake. This has already happened to the former Lake Tuggenersee.
Document 14: East Prussia: The Administrator of Prussia, the grandmaster of the Teutonic Order Maximilian III, son of emperor Maximilian II died in 1618. When Maximilian died, Albert's line died out, and the Duchy of Prussia passed to the Electors of Brandenburg, forming Brandenburg-Prussia. Taking advantage of the Swedish invasion of Poland in 1655, and instead of fulfilling his vassal's duties towards the Polish Kingdom, by joining forces with the Swedes and subsequent treaties of Wehlau, Labiau, and Oliva, Elector and Duke Frederick William succeeded in revoking king of Poland's sovereignty over the Duchy of Prussia in 1660. The absolutist elector also subdued the noble estates of Prussia.
Document 15: Rhine: The hydrography of the current delta is characterized by the delta's main arms, disconnected arms (Hollandse IJssel, Linge, Vecht, etc.) and smaller rivers and streams. Many rivers have been closed ("dammed") and now serve as drainage channels for the numerous polders. The construction of Delta Works changed the Delta in the second half of the 20th Century fundamentally. Currently Rhine water runs into the sea, or into former marine bays now separated from the sea, in five places, namely at the mouths of the Nieuwe Merwede, Nieuwe Waterway (Nieuwe Maas), Dordtse Kil, Spui and IJssel.
