Jonas Jonasson Bronck, or Brunck, was born in Jonkoping County, Smaland, Sweden. The municipality of Sävsjö claims the honor of his birth in the nearby hamlet of Komstad. He was about 40 at the time of his marriage, born around the year 1600.
Jonas Jonass Brůck and Teůntje Jůriaens were married 6 July 1638 in Amsterdam. The marriage banns were issued 18 June 1638 between Jonas Jonass brunck and Teuntje Joriaens at Huwelijksintekeningen van de Kerk (Church).

Jonas Bronck Signature 1638
Jonas and his wife sailed from the Hoorn aboard the "Brant van Troyen" ("Fire of Troy") after April 1639. They arrived in New Amsterdam before 16 June 1639. On board with Jonas were Peter Andriessen and Lourens Duyts, who leased land from Jonas, as well as Clara Matthys, a housemaid who later eloped with Gerrit Jansen. The ship also carried cattle.
In 1637, prior to his marriage and his emigration, Jonas Bronck acquired a patent from the Dutch Government for "The Ranaque tract, north of Haerlem." He would also purchase the same land, at 40°48′13″N 73°55′33″W between the Harlem River and the Aquahung (later called the Bronx River) from the natives.
“The invisible hand of the Almighty Father surely guided me to this beautiful country, a land covered with virgin forest and unlimited opportunities. It is a veritable paradise and needs but the industrious hand man to make it the finest and most beautiful region in all the world.” 
Here in this beautiful country, Jonas built a house of stone with a tile roof. He had a barn, and a tobacco house and a hay barracks, horses and pigs. Besides growing tobacco and other crops, he must have sold milk. Five milk cows are more than one small family needs for their own consumption. He had farm implements, including 23 new axes. He also had amenities, that indicated his wealth and education. He had silver spoons and a silver cup and other items of silver. Besides his guns he had a rapier and a japanese cutlas. He owned a black satin suit and a gold signet ring. He also owned many books in several languages. Most of the books were religious in nature. Jonas called his home Emaus, from the biblical location where the risen Jesus met two followers and talked with them.

Jonas Bronck had no known children. It was believed for many years that Pieter Bronck, was the son of Jonas. For various reasons this has been called into question. Among these is the 1643 will of Pieter who left his estate to Engeltje Mans because “his father, mother and other friends are far from here,” implying that his parents were alive but Jonas had been dead for about 6 months.
Jonas died probably in 1643 in Bronk's land, Nieuw-Nederland (now The Bronx, New York). An inventory of Jonas' estate was taken 6 May 1643, by Teuntjen Jeuriaens and Pieter Bronck, in the presence of Everardus Bogardus, minister, and Mr. Jochim Pletersen Kuyter, who were guardians of Teuntjen.
Each of New York City's five boroughs is also a separate County. The Bronx, the only borough attached to the mainland of the North American continent, is named in Jonas Bronck's honor.
