I´m searching for Emil GROEGER (GRÖGER), my granduncle. He was born in the area of Allenstein (now Olsztyn) in formerly East Prussia around 1900. He was a craftsman and left Germany in the early 1930s for South Africa, then settling in Pretoria. He came back for a visit to Germany only once, right after 1945. What ever happened to him? When did he die? Did he have a family and descendants? Does anyone know? Thanks for report.
