Not much personal information from Dutch life in Bengal or any other of Dutch settlements in India can be found in the VOC archives in the State Archives. The reason for that is that the VOC correspondence only covered official and business information written by VOC employees and shared with the local head office and the central office in The Netherlands, The VOC also censored all letters. An exception can be made for Jan Albert Sichterman (1692-1764), who spent nearly 15 years in Bengal. In 1742 he used his own money to build a church tower near the river in Chinsurah.
That we know a bit more about his and his family’s life is due to a personal history dug up by a descendent in the Sichterman family. Wiet Kühne-van Diggelen.
Wiet wrote the book in Dutch. For my research for the Indian specialists working on the revamp of the Dutch heritage in Chinsurah I summarized her book about Jan Sichterman. See Nearly fifteen years VOC service in Bengal: Jan Albert Sichterman.
