The History of Harlem by James Riker 1881 published in New York in which details the circumstances of Sebastian Van Kortryk in Kortrijk (a Flemish town now in Belgium) and the subsequent birth of his two sons in Leerdam in Holland. The older son Jan lived in South Holland at Beest two miles north of Leerdam where his four children were born. Michiel settled in Schoonrewoed also near Leerdam; there he had four children. On April 16, 1663 Jan and Michiel Bastiensen van Kortryk set sail from Leerdam in Holland in a ship called the Spotted cow with Captain Jan Bergen for New Amsterdam and a new life. The sons and grandsons of these two emigrant brothers took several names including Kortrecht/Kortright/Cortright/Courtright. Other major sources are the records of the Dutch Reformed Church, the work of John Howard Abbott 1922 entitled the Courtright (Kortright) Family.
