German connection

Back in the 60's I lived in South Africa and became friendly with a couple of german guys who had backpacked their way around the world. They were a curious pair, both really nice, but came from different backgrounds. One was from an aristocratic family and always wore shirts with the family motif on the pockets. Some five years after I left South Africa for England and they too had travelled to South America. I was walking across Trafalgar Square when these two guys appeared in front of me. We were both excited to see each other again, then we had lunch and they had bedded down for a couple of nights in my flat. They left and I never saw them again. Some 20 years later I had married and my husband worked for a German company in England. The Chairman of the company turned out to have the same surname as the Aristocratic German I remembered. He wasn't the same person as the ages were wrong, but he did have that same motif on his shirt.
