My mother Anna Heman born Feller Was born in Sumatra, Padang Toyo Lava the 31th of may1921. She came back in Switzerland with her fatherCesar Feller and brother Peter Feller at a early age and had no more news about her mother since. I would like any information about my grandmother Sinoa . She had three children: Heidi, Peter and Anna,with a swiss businessman named Cesar Feller originary from Bern. He came back to Switzerland in the years 1930 on a ship with the three children but Sinoa stayed there. She was probably originary from Padang.May be from the tribes Batak, Minangkabau or Nias. Thank you for help Barbara Heman.
