Gerardus Dingeman van der Sluijs Your interest in this area is most welcome, and there are many profiles that still need sourcing and development. I mentioned the multiple language issue as example; we have ability to add languages, and that helps a great deal in reconciling genealogies from different countries.
In addition to the sources you’re using may I also suggest you work with the late Leo van der Pas’ site

You’ll see he differs slightly from what we currently have in this area, but his citations are top notch, and we understand (by discussion) the discrepancies.
