A Johannes Mesman from Vlissingen, The Netherlands joined the VOC (Vereenigde Oostindische Compagnie) on October 19, 1785 and sailed to the East Indies on the "Zeenimf. On September 20, 1789 he married Maria Heilman from Makassar. They started a "dynastie" of merchants and residents. Johan(nes) David was Resident of Maros, and there is a Johannes Willem who was Resident of Japara and later Cirebon.
In the book "Being 'Dutch' in the Indies is mentioned a lot about the Mesman families. In the KITLV library in Leiden I have found the handwritten memoires of Emilie Mesman. You can contact me for the PDF-file.
