I don't have information regarding Johan van Affelen van Saemsfoort, however he could be related to my late grandfather, Christian van Affelen van Saemsfoort. He was a former KNIL personel, passed away in 1958 and buried in Jakarta. He was married to my (late) grandmother Sarah Halau. My grandmother relocated to Ambon after his death. Their children are Samuel (deceased), Louisse Anthoinete (my mother), Lodewijk (deceased) and Ferdinand. We would greatly appreciate any information regarding my grandfather's family, if you have them.
