About Jonas Bronck


Jonas Bronck

Jonas, in his wedding certificate from1638 calling himself Jonas Jonsson Bronck and giving his age to 38 years born somewhere between 1575 and 1600. He was the son of Morten Jespersen Bonck a Lutheran minister. He was raised in Tórshavn in the Faroe Islands but his origins are uncertain. There is a street bearing his name, Jónas Broncksgøta. In 1619 he went to school in Roskilde Denmark and eventually made his way to Holland. He married his Dutch wife Teuntje Jeuriaens Slagboom on 6 July 1638. with a wedding certificate referring to him as Jonas Jonasson Bronck.

Jonas was a sea captain before coming to the New World. In the spring of 1639 Jonas and a party of other emigrants, including his good friend Dane Jochem Pietersen Kuyper, departed the Dutch port of Hoorn. In addition to passengers and crew, their ship, De Brandt van Troyen (Fire of Troy) was laden with numerous cattle. On June 1639 the vessel was seen in the harbor of New Amsterdam.

He navigated up the East River, and made his home on a piece of land acquired fron the Indians, across the Harlem River from the village of Harlem. The land was within the territory of the Siwanoy and Wecquaegeek groups of Lenape who inhabited it at the time of colonialization.

His farm was located at what now is 132 Street and Lincoln Avenue in Mott Haven. He gave his name to the Bronx River from which the borough Bronx and Bronx received their names.

In 1981, after conducting research in the Netherlands, Sweden, and New York, G.V.C. Young O.B.E. published the 19-page manuscript The Founder of the Bronx. It states that Bronck was born circa 1600 in Komstad in Småland, a historic province of Sweden adjacent to the then-Danish province of Skåneland, at the time inhabited by Jon Nilsson and his wife Marit Brunk. Jonas Bronck made his way to the coast on the Baltic Sea where he became a sailor in the Danish merchant marines, and later transferred to the Dutch fleet.[13][14][15][16] The theory that Bronck was a Swede has been adopted by the official historian of the Bronx, Lloyd Ultan,[17] the Bronx Historical Society[18] and other publications.[19][20]
