Unlikely meeting

About 14 years ago, one of my best friends was fed up with her teaching job in the UK and applied to do an exchange in Australia - she was successful and agreed an exchange with a man from South Australia who came over to live in my friend's 2 up, 2 down in Lancashire with his wife, while my friend took on his small holding in the Adelaide Hills. My friend was going on her own, and as I had grown up in Australia (Melbourne) I offered to go out with her to help her settle in and to have a 3 week holiday with her before she started work. On arrival the daughter of her exchange partner met us and took us to the property (at this point she knew nothing about me other than my first name and that I was a 'friend who had come for a short holiday') The next day she took us in to Adelaide, and as we were waiting in a bank to change some money she noticed my surname on my passport and immediately asked me if I had relatives in Canada - my first reaction was 'no' but then remembered that my father's cousin had gone to live in Canada as a young man and remained there (same surnmae as me) It turned out that her father had done a previous exchange to Canada and the whole family had gone. They had lived near to my father's cousin and were great friends with his daughter!
