Baron Jan Cornelis van den Heuvel^{[lower-alpha 1]} (December 23, 1742 – May 6, 1826)^[1] was a Dutch born plantation owner and politician who served as governor of the Dutch province of Demerara from 1765 to 1770 and later became a merchant in New York City with the Dutch West India Company.

Van den Heuvel was born on December 23, 1742, in Maastricht in the province of Limburg, Netherlands. He was the son of Abraham van den Heuvel and Jacoba Johanna Henrietta Hesselt (née van Dinter).^[2]

His paternal grandparents were Jacob van den Heuvel and Hermanna Henrica Cuper. His maternal grandparents were Andres Matthias Hesfelt van Dinter and Jacoba Henrietta Martini.^[3]

In 1765, Van den Heuvel was appointed Commander (an equivalent to the colonial governor) of Demerara, which was a historical region in the Guianas on the north coast of South America (which is now part of the country of Guyana) located around the lower courses of the Demerara River. In Demerara, he owned two plantations.^[2]

At the time, it had been a Dutch colony since 1745 when it was separated from Essequibo. Van den Heuvel served until 1770 Demerara would remain mostly under Dutch rule until around 1812 when it merged into Demerara-Essequibo and was ceded to Britain by treaty between the Netherlands and Britain, becoming known as the county of British Guiana from 1838 to 1966. Its main town was Georgetown (which was known as Stabroek during Dutch rule).^[4]

Van den Heuvel was married to Maria Catharina Storm van 's Gravesande (1734–1771), the daughter of Laurens Storm van 's Gravesande and Lumea Constantia van Bercheyck.^[3] They were the parents of:^[3]

After Frederica's death upon his relation to the United States, he remarried to Charlotte Augusta Apthorp in 1794.^[10] Margaret was the daughter of prominent New York landowner Charles Ward Apthorp and his wife, Mary (née McEvers) Apthorp.^[11] Together, they were the parents of:^[2]
