descendants

I would like to get in touch with descendants of Olga Vogel, born Fürth. Her son Robert went to Lima (Peru) during the nazi-regime. He became a surgeon there and had( maybe) a private clinic. His wife, whose name I don't know, was in the early fifties ( about 1951) in Munich Germany) and visited relatives. Robert and his wife had a son Adelbert.
Is there anybody, reading this, who happens to know a descendant?
