An incident that occurred lately is an example of this. A man from Stockholm was visiting London, where he thought he had no relations or, if any, they dated from perhaps a century ago. In the street one day someone called him by name. When he turned round, the man who had called him excused himself, saying, "I am sorry, I have made a mistake." But he asked, "How did you know my name? The name you said is mine!" And when they spoke together they found that they were cousins, although very distant ones.
