travel coincidence

I am a Canadian who was married and living in Canada until 1971 when my marriage broke up. I came to the U.K. at that time, met my current (English) husband and remarried shortly after my divorce came through, and we have been living in England ever since. Although the divorce was quite amicable I am not in contact with my previous husband or his family. About 20 years later (in 1990 or thereabouts) my second husband and I were flying home to the U.K. after a week's spring holiday in Portugal. We were seated in the same row as an elderly English couple and we got chatting with them. This couple ran a pub in Henley called The Little Angel on the Bridge. After some conversation on that topic I remarked to the lady that in both looks and speech she very much reminded me of a Canadian relative I used to know many years ago (my ex-mother-in-law). Further talk and investigation revealed that this lady was in fact actually my ex-mother-in-law's first cousin! She had never been to Canada, however my ex-inlaws had been to England on holiday and had visited her and her family in Henley. The original family emigrated from Scotland to Canada during the Highland Clearances and settled in southern Ontario, and I believe this lady's father then left Canada to seek his fortune in England in the latter part of the 19th Century. She would have been born in the early years of the 20th Century. I hope you find this coincidence as interesting as I did.
