https://www.geni.com/projects/South-African-Stamouers-Progenitors-M... lists the VOC ships which arrived in South Africa around the date which Christoph Grunewald is thought to have landed. Does anyone have any more information in this regard.
Hello. Matt i draw you're attention to reattach done by Mariusz Kowalski, page 70, which states that Christoffel Grunwald arrived to the Kaap de Goede Hoop in the year 1688. Maybe that helps to refine your search a bit. The website is sciendo.com and titled Poles in the Dutch cape colony 1652-1814.
Very interesting reading. Who knew!
Take care
