Further to my previous message on 4th March 2007 re Fredrik Leonard WOLFF, details of his grandparents from mother's side r Leonard ERTZINGER(Died 19/05/1836) and Johanna Frederika van STRALENDORFF(Died 25/07/1840), both were buried at Pasar Kliwon burial place in Solo, Cntrl Java. Other surnames directly linked with his family r van der Heyde, Chambry, van den Engh, Bronkhorst, de Jong. Also some names linked with his siblings/parents such as Jacob Thomas BASTIAAN, Johannes Bernardus Wolff, Elenora Engelina and Johan Leonard ERTZINGER might be useful.
Fredrik's place of work was in Tarikngarum and his residency was in Kepo, Soerakarta in CentralJava.
Fredrik's date/place of birth, date when he died, burial place, details of his siblings, parents, cousins etc r still unkown to me.
Perhaps with the aforementioned info someone could enlighten me further.
Look forward to receive positive feedback. Thank you..
