To my opinion it looks like the surname Warmbier is a typically Dutch surname, it means "warm beer" in Dutch. But I could not find the surname in the Netherlands birth records or death records and also not in the South African records, instead I did find some very old records (Family Search) in Prussia, Germany around 1744. So this surname must be of German descend. In those days there was a language called "Neder-Duits", which was some kind of Dutch-German mix, so that is most probably why it looks like Dutch to me, but it appears to be German. Warm beer is in the German language nowadays "Warmes beer", but most probably in old German it was the same as in Dutch "warm bier = warm beer".
