Everything tagged: schooners to Japan

In trying to trace a possible relative listed in 1872 at "China Sugar Refinery East Point "- was that part of Jardine Matheson & Co ?

The books I've consulted don't go into this subsidiary company.

Did they ship sugar to Japan an bring back silk?  Does anyone know where to find any records of the ships, the voyages and the Masters?

thank you for your help,
