Sigfrid Orre, big game hunter and adventurer, born in 1890 in Linköping. He had two brothers, Wollmar and Torsten. In Linköping, he became a student and reserve officer and continued his studies at the University of Stockholm. He wanted to be a lawyer. At the outbreak of World War I he interrupt his studies for emergency service in the regiment in Linköping. By accident he became partner in a Swedish export and import firm in Johannesburg, South Africa. He bought a farm in Zambia (Northern Rhodesia at the time), but sold after some time the farm and supported himself instead as a professional big game hunter. He served as a supplier of fresh meat for various mining and forestry companies' behalf. He worked at times for the Belgian great company, Union Minière and led projects with timber cutting and prospecting. During his travels as a big game hunter and a prospector in Central Africa, he got to know the barotse people who gave him the name "Mwendujora", which roughly means "chieftain who has traveled far and seen much."
Eventually he settled in the city of Lubumbashi (formerly Élisabethville or Elizabethville) in the country of the lunda people in Katanga in southern Congo. Here he was given the name "Mirasa" (colostrum). In the final years of Katanga, his eyesight deteriorated and in 1961 he was able, with the help of Swedish UN soldiers, to return to Sweden. He lived in retirement in Mjölby until his death in 1967. During this time he contacted Ake E. Andersson for help to gather his memories and experiences in a book. The book was written but never published
Sigfrid Orre had a daughter, Natalia Dinah Orre, born on the 25/12/1924, and a son, George Orre, born in 1938. Natalia married a Swedish man, Sigurd Gustaf Hjalmar Schönström. One of their grandchildren, Carolyn Sigedt, contacted the Museum of Ethnography in 2013 and gave this information.
