Subject: Re: OPA - niet helemaal gelukt I carried out some further Knol research. There is indeed a Knol family book. There is even a Knol family club. It issues "De Knollentuin" containing the genealogy of the different Knol families. The Stitswerd Knol genealogy starts with Jan Knol marries NN. His son Menke marries 1699 Frouke Lues daughter of Lue Sijwerts.
