Janneke's last name was actually Dirckse. Back in those days, the Dutch and Norwegians (Dirck was born in Norway) used what's called the "patronymic" system, that is, the children's last name would be a form of the father's first name. They didn't adopt the family name system until the British established control of New York. (Christina's brother, Volckert Dircksen, named all his kids Volckertse(n), but then they kept it, and later Anglicized it to Fulkerson.) There's a large treasure-trove of information on this family and period at http://www.fulkerson.org/.
Christina's parents were among the first Walloon families to settle in New Amsterdam in 1624. Her father's first name was variously spelled Guillaume, Ghislain, Guleyn, and Willem, and his last name was usually spelled either Vinge or Vinje (the Dutch phonetic equivalent). Being Walloon, they apparently didn't follow the patronymic system in naming their children, all Vigne or Vinje. Their son, Jan Vinje, (Christina's brother) was probably the first European born in Manhattan.
