In the pedigree of my children there is Heynemann Beer, born in Mackbergen, Germany 28-4-1750. He came to the Dutch Indies in 1770. He lived in Djokjakarta and Semarang, Java in 1777 and 1798. In many publications on him he was married with (1)Kastoeri or Kasturi and (2)Melati, both Javanese women.
Following this publications Kasturi is a daughter of (a son of?) the regent (bupati) of Semarang, Kyahi Kadipati Soerohadimenggobo. She was a granddaughter of prince Mangkunegero, prince of Mataram.
Besides these publications there is no evidence she was really a descendant of the Javenese nobility. Can anyone help me with more information on Kasturi ? Are there any sources where she is mentioned ?
