I'm from Holland.
According to the Slave-literature, slaves owned by Mr. Wil-kens received the name Kens-wil once they were deliberated. One of my ancestry's , W.J. Kenswil lived in Suriname in that periode. I wonder if he was a relative of your husbands grandfather. Willem Jacobes Kenswil was merried to Mrs. Emanuels. If anyone knows some more about their origine, please let me know.
The noumbre of deccendants of this couple must be very large.

* By the way : I do have an interesting idee to let this
succesfull W.J. Kenswil relive. It takes relatively small
amount of money when enough decendants participate.
