Christian Theodor von Pincier

Captain Christian Theodor von Pincier, later known as Theodore Pincier, Esquire, or as Theodore de Pencier (1750 – 1824), was a Brunswick Army 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 the 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, then to dePencier & Depencier. Theodor was the adopted child of Braunschweig Army General von Pincier.

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.
