General Notes
C Willem Meyer (oudste van 9 kinders) gedoop 20-1-1715 te Drakenstein, Paarl (1) burger te Drakenstein, getroud 26-6-1745 te Paarl met Elisabeth Loots (2) dogter van stamvader en heemraadslid Jan Loots van Amsterdam en Maria Joubet. Op 21 jarige ouderdom (17-11-1736) onderneem hy sy eerste amptelike landstog na die binneland en keer terug op 24-11-1737 (3). Die togte was onderneem om olifante te skiet aangesien daar 'n grootvraag na ivoor in Batavia was en die Kaapse regering ook materiele belange in olifantjag gehad het. Hierdie landstogte word beskou as die eerste uitwaartse beweging van die koloniste wat mettertyd met hulle vee 'n leefwyse gemaak het om al hoeverder Oos te trek.
