A Pakistan coincidence

I am afraid this may be a little longwinded but the coincident I feel is quite remarkable. I am seventy yeras of age and my father back in the years around the 1950's was serving in the Gateshead police force as a constable. He was of the no nonsense category and he had a colleague by the name of Corrigan who had similar attitudes to miscreants. So to get to the coincidence. I am in Islamabad around 1984 and was my habit on a Friday I hailed a taxi from the front of the Holiday Inn to take me for the ride up to the foothhills of the Himalayas to Murray and beyond. Once seated comfortably in the taxi the taxi driver asks me where I am from. England I reply ! Then you will know my friend. Yes I reply, with a population of nearly 60 million of course I said in jest. The taxi driver had been seconded to look after an Englishmanin in Islamabad for a number of weeks and had become familiar with the background of his client. His client was the son of constable Corrigan who lives not more than one mile from where I live in Whickham Newcastle upon Tyne. I am the son of his colleague.
