Cambridge coincidence quite literally [et al.]

I have a Cambridge coincidence for you, quite literally!! I also have several other coincidences I can relate. 1) My grandparents lived in Barton Road, Cambridge in the 40s and into the 50s and I visited them from time to time. Since 1972 I have been living either in Portsmouth itself or nearby. I used to be a member of the Anglican cathedral congregation. I got to know the chaplain to Portsmouth Grammar School and found out that he had been educated at Cambridge. Nothing at all out of the ordinary about that. I also found out that he was a Cambridge townsman, i.e. had been born there. Still nothing extraordinary. We then got talking one day and he mentioned he had been born in Barton Road. Quite a coincidence! What number? The same number as my grandparents! Now that was a coincidence!! I was myself born in Cambridge in what was then, for a while, a nursing home. My other coincidences almost all also relate to my time in Portsmouth 2) I used to work in the University Library. My most noteworthy coincidence (to me) happened while visiting my roots and my relatives in East Anglia, not in Cambridge but near Bury St. Edmunds. I used to stay in a particular hotel probably once every year or two i.e. very occasionally in the overall scheme of things. I came down to breakfast one morning and who should be there but a work colleague from Portsmouth who worked in the same room!! Neither of us knew that the other would be in this neighbourhood and neither of us were staying more than two or three nights. 3) I have a very good German friend who lives on the outskirts of Hamburg and I used to go over there using the Harwich to Hamburg overnight ferry, about every two or three years. Who should I find on board on one occasion but another work colleague from Portsmouth!! Again neither of us knew that the other would be there and neither (I think) knew that the other had a German connection. I did not know this chap particularly well as we worked in different buildings. 4) I have other coincidences related to travel which were coincidental but much less so. I was at Heathrow, about to fly off on holiday somewhere. I was milling about in the check-in area when who should I see but someone I knew from the wider University who was about to get on a flight elsewhere and whom I knew from our common interest in cricket, not via the library. I also remember an incident at Victoria train station in London. I was waiting outside the ticket barrier on the concourse when I thought I recognized someone from my University days which lay years behind us and it was her! 5) Going back to my German friend, he and I share a date which is particularly significant to our families. He was born on this date and my parents were married on this selfsame date (and I appeared almost exactly nine months later!!). It is a coincidence of sorts but he and I got to know each other at Exeter University via a little Fiat 500 car called Hannibal that he used to drive. The German numberplate was one I recognized because my father knew someone in this place and we had stayed with her! I approached him solely because of this plate. A Marshall
