Hi Dewald, The SAG book no 5 page 372 indicate that Joachim Heinrich Martens came from Brandenburg, arrived in 1747 at the Cape of Good Hope on the boat De Kasteel from Tilburg. He later became a burgher and lived at Stellenbosch. He married Jacomina VAN DEN BERG on 5 August 1759. The date of her death became part of her profile after a merge and I have no idea who got that information.
