Almost all Ketelaars have their origin in either Oisterwijk or Nuenen. They are two towns in the present-day province of Noord Brabant. The family Ketelaars that hails from Oisterwijk has been wel researched by W. de Bakker in the article "Ketelaers alias Den Steenbecker" that appeared in the periodical "De Brabantse Leeuw, July-August 1981. It seems no one has looked at the other group of Ketelaars, with just as many living descendants, "Ketelaers alias Van Nuenen". As a Canadian I am limited by what can be found on the Internet and by research done by others that has come my way. I could not classify five couples listed in genlias.nl, living at around 1800, as belonging to either group. They are: Hendrik Ketelaars and Petronella Ameis from Geldrop, Johannes Cornelis Ketelaars and Catharina Verhagen from Tilburg, Johannes Ketelaars and Maria Plompen from Ossendrecht, Johannes Ketelaars and Johanna Reijnders from Valkenswaard, and Laurens Ketelaars and Maria Kessels from Heijthuijsen. Are they too related to one of these groups?   This is the ancestry chart for the children of Laurentius Ketelaars and Cornelia Willems.   If you are looking for the previous Ketelaars.ca website. You can still find it here..
