Christian Theodor von Pincier
Captain Christian Theodor von Pincier, later known as Theodore Pincier, Esquire, or as Theodore de Pencier (17501824), was a Hessian auxiliary officer who served on the British side during the American Revolution. Following the peace treaty, he became a settler and well-known surveyor in colonial British Quebec. He was apparently an illegitimate son of Charles I, Duke of Brunswick-Wolfenbüttel, who was adopted into the Pincier von Königstein family, known as von Pincier in German and Swedish, or de Pincier in French. They were members of the Swedish nobility. Throughout his military career in German-speaking regiments, he used the surname von Pincier, but, later, in Canada, he adopted a French version of his surname, altering the spelling to de Pencier. He left many descendants in Canada. Some became prominent:  and include an Anglican archbishop, The Most Rev. Dr Adam de Pencier, and that prelate's grandson, Michael de Pencier, a decorated Canadian publisher, entrepreneur, and environmental conservationist. Family members continue to spell the surname, de Pencier or dePencier. Birth
Christian Theodor was born out of wedlock in Braunschweig in 1750. He was the illegitimate child of Charles I, Duke of Brunswick-Wolfenbüttel and a married Frenchwoman. His mother's husband, a French grenadier captain named de Martigny, later killed himself, perhaps out of jealousy. Widowed, she remarried to a Franco-Swedish nobleman belonging to the family of Pincier von Königstein. Christian Theodor was never recognized by his father, and, instead, was adopted by his mother's husband, Georges-Henri de Pincier, a descendant of Baron Pincier (#109), whose family had received their patent of nobility in Stockholm from Charles XII of Sweden in 1698. From this step-father, young Christian Theodor gained the surname which he bore. He was to use it for the rest of his life prefixed by one or other of the German or French noble particles von or de as the situation warranted. This was a common practice of the time among the nobility, who alternated between German and French custom, as they moved about Western Europe during their careers and travels. Early life
At age 14, de Pencier volunteered as a cadet and learned to ride in his father's ducal stables. His extraordinary horsemanship by age 16 enabled him to become standard bearer for his military unit. He received his first commission the next year, and, in 1771, at age 21, was promoted to lieutenant. Between 1773 and 1774 he travelled in France and Italy, visiting Florence, Rome and Naples. During the period of his early life, he was celebrated for his numerous love affairs and rumours of liaisons with many noblewomen. In 1775, he wrote a poem dedicated to donna Elisabeth de Baffa Trasci (1750–1795) an Albanian aristocrat whom he met in Naples. She refused his marriage proposals, but gave him an illegitimate daughter, Carlotta Maria Amalia. The poem was published in 1782 under a pseudonym. Theodore became a superb horseman and studied literature, poetry, astronomy, engineering, and also military artillery strategy and tactics while mastering French, German, Italian, Latin and English. Army career
As Theodore de Pencier was assigned to Prince Frederick's regiment as part the Hessian cavalry of General Baron Friedrich Adolf Riedesel, the young officer was destined to see action in North America during the American Revolution. In June 1776, he and 4,000 Hessian 'mercenaries,' many of whom had not left Hesse-Cassel willingly, arrived in Quebec. In the early summer of 1776, Sir Guy Carleton, the British governor and commander-in-chief in Quebec, tasked General John Burgoyne with driving the invading Americans out of the province and south into New York. Faced with Burgoyne's 6,000 British troops and Riedesel's 4,000 German mercenaries, the weakened Americans retreated to Sorel at the confluence of the St. Lawrence and Richelieu rivers. The Americans under General Horatio Gates retreated, this time to the safety of formidable Fort Ticonderoga. The Hessians, much to the frustration of Baron Riedesel, were largely unprepared for pursuit. Historian Thomas Randall compared "the south-moving procession of British infantry and German infantry and cavalry, batteries of artillery, ammunition wagons, supply wagons" to a travelling circus. The Hessians seemed alien to their British counterparts. They often sang psalms on the march and caught and tamed wild animals. Baroness Riedesel and her entourage travelled by elegant caleche, while the Brunswick Dragoons, short on horses, had to march with their enormous cocked hats, thick coats, leather breeches, and jack boots rising above their knees. Captain de Pencier, as an officer, was fortunate to retain his mount. He also avoided the fate of many Hessians: death under American fire by sharpshooters using the deadly accurate Pennsylvania flintlock. With significant losses and failed manoeuvres on both ends of the Mohawk Valley, Lake Ontario, and the Hudson, Burgoyne surrendered after the Battle of Saratoga in the face of heavy Yankee artillery and more than 14,000 men mustered by Gates. The Hessians had recently suffered a major defeat at Bennington with 200 dead and many more imprisoned. De Pencier likely encountered frontier spies Roger Stevens and Stephen Burritt for the first time here at Bennington. Stevens, imprisoned with Burritt after the battle, became the first to settle the Rideau 15 years later, providing his homestead as a meeting place for de Pencier and his Rideau survey teams. The Americans reneged on the terms of surrender; rather than sending the captive Europeans home, they sent the British troops to prison camps surrounding Boston, while the other Hessian captives were sent to camps in Pennsylvania and Virginia. Officers were put in cramped quarters, with as many as six to a room; Baron Riedesel, his wife and children, initially suffered too, living in small, cold surroundings. All found their conditions improve as the British began paying outrageous American fees for the food and lodging of prisoners. Theodor did not participate in the Battle of Saratoga and remained stationed at the fort in Sorel Quebec for the remainder of the Revolutionary War (1776-1783). De Pencier, by then a widower, returned to Europe in 1783 with most of the Hessian prisoners. He stayed only long enough to receive his honourable discharge from Prince Frederick's regiment and obtain British naturalisation. He returned to Canada the next year, but could not find employment despite letters of recommendation from Baron Riedesel. Signs of his stress began to emerge at this time. He was described as 'haunting' government offices with a 'drooping spirit,' though he was buoyed temporarily by a grant of 20 pounds. He remarried and his second wife gave birth to a second son, Luke. A Loyalist grant of 300 acres from General Haldimand proved to be unmanageable. De Pencier was neither a lumberman nor a farmer and lacked the necessary financial and physical resources to clear the land. He wrote that his hands were "accustomed only to the use of the sword and the training of horses, too weak to cut down trees and to sell them at a profit quickly and advantageously." Finally, tired of feeding his family on meager rations, he took up land surveying at the age of 35. His sound education in mathematics enabled him to apprentice using a borrowed theodolite, a calibrated optical instrument used to determine relative position in surveying, navigation, and meteorology. In 1789, he received his full commission as a surveyor. His quarrels with the British authorities continued to consume him. He later complained to Governor General Sherbrooke that he had become a surveyor because he had very little money, despite the sacrifices he and his father had made in battle on behalf of the British. De Pencier received instructions in 1791 to survey the first townships on the Rideau River in what was to become modern-day Ottawa. In Canada, after his first marriage with Marie Demerais, he remarried Charlotte Rivard Bellefeuille on November 4, 1785, at the Protestant Church in Trois-Rivières. She was born in Sorel, May 7, 1766, the daughter of Jean-Baptiste Rivard and Marie-Josephe Lesieur. Descendants

Impoverished, hopeless, and indigent, de Pencier committed suicide in a Canadian military asylum on April 18, 1824. On April 19, shortly after Easter 1824, the remains of de Pencier were placed in a modest grave at Fort William Henry by the Richelieu River in Quebec. Moments earlier, a British subaltern reached into de Pencier's coffin and removed his sword, a final act of discourtesy to the dead Hessian officer, and probably a reflection  of the fact that suicide was then a crime. From the register of the Anglican parish of Christ Church, William Henry (now Sorel, Quebec) comes Capt. de Pencier's burial entry, viz. :

"Buried on this nineteenth day of April one thousand  eight hundred twenty four Theodore Pincier Esquire formerly of the German troops in the British Service and late a sworn surveyor of this province." Further reading
