Hallo Jakob
Got to www.stamboomzoeker.nl Click on "english" (top right of the page) fill in "van het Kaar" at "surname" click search and you will find 85 van het Kaars, most of them in the Zaanstreek. The Zaanstreek is officially called "Zaanstad" now. Years ago yhe Zaanstreek was 7 villages but these villages became one township somewhere in the seventies. If you want to know more about this ares please mail me. I was born there. nicokan@hetnet.nl

Regards

Nico
