This site deals with the Grobler family (including Grobbler) and Grobbelaar (including Grobelaar) families. My goal is to make the family tree available on the Internet. It is supplementary to the works of the late Dr. C. L. Grobler (Grobler, 1987) and Dr. Paul Grobbelaar (Grobbelaar, 2012).  I am particularly interested in the ancestors of Jan Grobler, and I am trying to identify possible relationships with Groblers in Europe to expand the family tree.  So far unsuccessfully.  I also include a chapter on genetic genealogy that complements conventional genealogy.
