Portrait of the Cock Blomhoff Family, attributed to Ishizaki Yushi, 1817
When the director Jan Cock Blomhoff travelled to Japan in 1817, he did something highly unusual: he took along his family. Western women were not allowed onto Deshima. Titia and her young son thus had to leave the country a few months later. A Japanese artist portrayed the family. From left to right are: Jan Cock Blomhoff, the wetnurse Petronella Munts, Titia Cock Blomhoff-Bergsma, her son Jan and two Javanese servants.
