Franz Friedrich Thönemann, mayor in Warburg, was married to Maria Elisabeth von Hiddessen in his first marriage; six children, among them Johann Vitus Christoph, born on 27 March 1693 and Johann Konrad Franz, born on 18 October 1694, – both born in Warburg – were born of this marriage. Franz Heinrich Anton died young; Johanna Maria Helena Christiana, born on 7 January 1701 in Warburg, became Abbess of the noble ladies convent in Willebadessen (1741 to 1778). Johann Konrad Franz entered the priesthood, became Generalvikariatsassessor and later church council to the Elector of Cologne. No details are known concerning Maria Margaretha and Joseph Franz.
Johann Vitus Christoph von Tönnemann (see above) married Anna Maria Barbara von Lobenfried on 30 March 1724; they had ten children – six sons and four daughters. Leopold Joseph entered law (in the fourth generation), two sons Johann Konrad Franz Ludwig and Johann Jacob Franz Ludwig died young. The remaining three sons became officers. As a result of the intercession of the Supreme Court judge Prince Hohenlohe-Waldenburg, Johann Vitus Georg Ignatz received the rank of captain and fought with distinction in the various battles of the Seven Year War. On 18 July 1751 he married Anna Maria von Merckel from Würzburg. They had no children. He died at the age of 72 in 1799.
Bernhard Anselm Joseph, born on 21 December 1732 in Mainz, was named as a cadet and officer candidate from 1749 to 1751. Nothing is known of his further career. One of the daughters, Helena Franziska, born in 1741, married cavalry captain Bartholomäus von Chiari.
The daughter Maria, born in 1726, married (before 1751) Leopold Philipp Albert Adolf Erhard Graf von Galler; he came from senior officer circles, was kurpfälzischer privy councillor and district president in Neuburg on the Danube.
The last child of Johann Vitus Christoph von Tönnemann and Anna Maria Barbara von Lobenfried was christened Julian Gerhard Georg Wilhelm Xaver (born 1 March 1745 in Wetzlar; died 9 July 1810 in Warendorf). Before Wilhelm Xaver was transferred to Warendorf as lieutenant colonel, he lived as a major in Münster. There he owned the old Erbdrostenhof in the green staircase, which he had bought from Baron von Droste-Vischering. When he was transferred with his von Tönnemann regiment to Warendorf in 1778, where he became general, he sold the residence with the big park in the city of Münster to Princess von Galitzin; thus this house in Münster was to become a meeting-place of many famous people, such as Claudius, Goethe, Jacobi, Lavater, etc. In the following three years Xaver bought before the Emstor in Warendorf near Kalvarienberg from the former drill-ground a big area of about 500 Morgen (1 Morgen = 0.25 ha), on which he built a house, one-storey, brick in baroque style. This house soon became known popularly as the “Tönneburg” (Tönnemann castle). The deep red of the walls and roof harmonised well with the dark green of the surrounding coniferous forests. According to the plan, which is still available, the house had ten rooms, in addition plenty of farm rooms as well as kitchens and cellars, which were mainly accommodated in an extension.
The Tönneburg, it is said, despite all simplicity in construction, did not lack a manorial character. Here General von Tönnemann led a highly pleasant family life with his wife Margareta von Ernsthuys from Holland and the four children, Helena Arnoldine Agnes, who died at the age of 34, Catharina Theresa, who died four years after her marriage to Major Karl August von Teiffel on 4 October 1800 (he later became post master in Mülheim on the Ruhr – they had two children) as well as the two sons Christoph and Franz Karl. The diary of the 14-year-old Christoph from 1789 and 1790, which he kept in a precise and detailed manner, testified persuasively to this. There is a vivid picture of the life of a well-to-do, refined and spiritually interested family on the lowlands, also of the regular intercourse with the officers of the Warendorf garrison – the von Tönnemann regiment was quartered there – and the local dignitaries of the town, who were only a half an hour’s ride away from the Tönneburg. Plentiful staff was available at the Tönneburg to tend to all duties. Thus we learn from the diary that the Colonel’s wife got great support in her household from a Lisbet from Vechta, who had a position of trust. In winter the maids had to spin homegrown hemp, flax, and also hare wool. Four fat pigs, weighing 1100 pounds (550 kg) together were slaughtered annually, however were in no way sufficient for the big household and the many visitors; the shortfall in meat was covered by additional purchase. It is also reported in these papers about the workers, in contrast to the well-off people, who, as factories and firms were scarce, had to do the farm work mostly by hand. At this time a good farm labourer earned about 8 to 10 Taler per year, besides food and board, the maids much less. It was no rarity that in the later decades young, strong men wandered in autumn from one employment to another asking for work and were often prepared to take only their keep without pay for winter work. Thus it was also no surprise that many young men joined the army in order to have bread to eat; perhaps the smart, colourful uniform was also an attraction.
The diary report gives a vivid picture of the varied life of the officer’s family on Tönneburg, from the nice trouble-free youth of the children of General von Tönnemann’s family, of excursions far and near, also of learning with the father or with the employed teacher, who walked from Warendorf to Tönneburg every day. Occasionally the children were also allowed to travel with their father in their own carriage to Minster, a trip that took four hours on the not yet paved roads. The beautiful sights of the town of Münster and dining with the General made a big impression on the writer of the diary. The pleasant family life on Tönneburg was affected by the French revolution as the French freedom fighters by their success encouraged the people from Lüttich to have an armed rising. The sovereign, Earl von Hoensbruch, Bishop of Münster, fled from the growing revolt. On 21 October 1789 the von Tönnemann regiment in Warendorf was also called up; on 17 November 1789 the regiment marched off from their location in order to meet up with those from Münster. From these two regiments, as can be seen in the city annals of Münster, 1,000 foot soldiers, 100 cavalry, 27 artillery men with six cannon, six ammunition wagons and 15 carts left on 20 November at 8 a.m. from the Aegiditor to Lüttich and did not return until 21 months later. At the end of August 1791 the von Tönnemann regiment was in Warendorf again.
Colonel Wilhelm Xaver von Tönnemann died on 9 July 1810 in Warendorf. In the time of the French, his son Christoph was owner of Tönneburg. He was mayor of Warendorf for a long time. He married Maria Anna von Chiari on 30 July 1803; they had two children, Helena Franziska Maria Anna Wilhelmine (23 October 1805) and Norbert Joseph Bartholomäus (14 March 1807), who died shortly after birth. The daughter Helena Franziska Maria Anna Wilhelmine married Joseph Zumholz, the post inspector from Münster, on 9 August 1823.
Christoph’s brother, Franz Karl von Tönnemann, was born in 1774; he was also commissioned Münster first lieutenant and later left military service as a Prussian captain. He married Philippine Theodora Baroness von Westram in 1811; she was the daughter of Friedrich von Westram zu Gutacker, Major in Warendorf and his wife Maria Wilhelmine von Scheffert zu Kreyenborg; the remarriage was to N. von Glan from England. The son Christoph Wilhelm Julius von Tönnemann, officer in Münster, left because of a gunshot wound in his hand and became lord of the manor in House Farwick near Amelsbühren; he was born in 1815; got married in 1848 to Südlohn to Dieudonné Adela Countess von Looz-Corswaren, whose second son Alfons, resident in Ohio/USA sold the Tönneburg property in 1888. The first son Clemens died without children in 1924 in Wolbeck; Alfons, Albert and Ludwig went to America.
Thus the Tönnemann male lineage in Germany came to an end. As a result the title of nobility is also invalid.
The Tönneburg manor house burnt down in 1885; thus all the old files of the family from the Warburg time burnt. Alfons rebuilt the massive part, however sold the whole property which comprised 210 Morgen to the merchant Linnemann in Ahlen, who some years later sub-divided and passed it on to various heirs.
Thus the Tönneburg like the family von Tönnemann belonged to history too. Later the Warendorf Land stud was established on the site and after the First World War the Westphalian riding and driving school in Warendorf.
