Dear Ad and others, I have a document from the Rienks family dating back to1530, where Oenze Rienks in Hallum (if I'm right),Friesland, The Netherlands is the oldest known person from the family. I can send this document on request. It might be helpfull, save a lot of work and possibly extend the current version!!
So Long ! Rutger Rienks Enschede The Netherlands firstname.lastname@example.org
