ELEANOR RIGBY - What's the truth?

[Chris48]

McCartney says that the song title was made up from the names above shops that he saw in London. Yesterday I was at a family grave at St Peters in Woolton and thought I would have a quick look at the grave of Eleanor Rigby. It seems to me that it is too much of a coincidence that the song title was not taken from the grave in view of the fact that 1. St Peters has a strong association with The Beatles/Quarrymen and 2. Very close to ERs grave is the grave of somebody called McKenzie (as in Father McKenzie). So is McCartney telling the truth and if not why? Could it be a decent ruse on McCartneys part to stop beatles fans wrecking the grave site?
