Jessé de Forest was born between the dates of 1576 and 1578 in Avesnes. The family name originated from the village of Forest in the canton of Landrecies near Avesnes. Around 1609 he left Avesnes for Sedan and Montcornet before settling in Leiden, the Netherlands. In Leiden, he moved to obtain the right to emigrate with his own and other Walloon families to the New World. During his stay, he also met Pilgrim Fathers, future passengers of the Mayflower. De Forest served with Prince Maurice of Nassau as a lieutenant and captain. On February 5, 1621, Jessé de Forest sent a round robin petition, to Dudley Carleton, 1st Viscount Dorchester, English ambassador to The Hague. It applied for permission to settle about fifty Walloon and French Huguenot families that planned to follow the Puritans to America in Virginia. De Forest asked to dispose over a territory of eight English miles radius. Known as the Round Robin, this document is now preserved in the British Public Record Office. On August 11, 1621, the Virginia Company gave an agreement in principle, but raised some restrictions. The worst one was the refusal to allow the settlers to dwell together in one autonomous colony. De Forest declined this proposition.
It was de Forest's desire to establish a Colony in the New World, so that the Walloons could practice their Reformed Protestant Christianity without persecution. He then sought permission from the Dutch to establish a colony in what is now New York City. He was granted permission. He assembled approximately 60 families of Walloons and Dutch Protestants for the settlement in New Amsterdam, New Netherland. The first permanent settlers would arrive in New Amsterdam during May 1624. The foundation of the Dutch West India Company in 1621 had given rise to multiple opportunities. In 1581, Philip II of Spain had prohibited commerce within his realm with Dutch ships, including in Brazil. Since the Dutch had invested large sums in financing sugar production in the Brazilian Northeast, a conflict began for control of the area. Proposing his services and those of his fellow countrymen to the Dutch West India Company, de Forest informed them that a group of families practicing various trades had the opportunity to emigrate to America. The States of The Netherlands, realizing the importance of such an opening for future colonization, immediately consulted the Directors of the Company, who were meeting in The Hague. On August 27, 1622, after efforts delivered by Willem Usselincx and Jessé de Forest, the latter finally received the authorization to emigrate with other families to the West Indies. Left on reconnaissance for the coasts of Guyana in 1623, Jessé de Forest died on the Oyapock River bank, on October 22, 1624. His daughter Rachel and his sons Isaac and Henri and other family members joined New-Belgium ten years later in the territories surrounding the future New York City.
