OLGA EMILY BOISSEVAIN VAN STOCKUM (Olga Emily van Stockum-Boissevain in Dutch usage)
Olga Boissevain was the third-eldest of the Boissevain daughters. The two eldest were conventional and married well. The next two -Olga and Hilda - were more intellectually inclined but were not encouraged to get an education. Their mother Emily didn't think it was wise. The youngest two daughters, with the barriers broken, were well educated and married well. However, the youngest, Catherine (Teau), a great favorite of Eugen, died tragically young.
Olga married a sea-captain who was sent to put down rebellions in the Dutch East Indies in 1908. Baby Hilda came with him on the voyage by a commercial vessel (the "Ophir"). When they reached Java, Bram picked up a Dutch Navy vessel for him to command.
This is the ship that took Olga, Bram and Baby Hilda to Indonesia
