Maria de Silva married Otto Kopsch from Leipzig and they had at least one daughter, Princess Ottilie Kopsch, who was born in Apia/Samoa, as far as we know. Princess married in the early 1900twenties Heinrich Schneider, a physician from Saxony, who was the brother of my grandfather. They had one son, Klaus Fiame Schneider, a cousin of my father. Klaus Fiame died as a young soldier in WW II near the city of Nowgorod in Russia and is burried there. His parents died in the 1950ies in Germany.
