There seems to be some serious flaws with the current burger, theron, van der merwe tree. I think people are all over the place. For example the jacoba Lubbe mentioned above seems to be getting confused with Jacoba Johanna Theron (her grandsons wife). I am not even sure how to go about correcting all the issues on the tree. Last month I was in the Cape Archives so I am quite confident and can now see the issues. Any bright ideas about how to unscramble because I don't want to upset anyone else's trees!!
