Eleanor Rigby Question

Didn't Paul state that he thought up the name? That would seem odd because
isn't the actual grave at the cemetery where the famous Woolton (sic?) Fete

Edvado...

Yes, and I'm sure Paul and the other Beatles all spent countless hours
memorizing every single name on every single headstone in the cemetery
in hopes that they may need a character name someday.

'PAUL: I had a bit of trouble with the name [Eleanor Rigby] .... I was
very keen to get a real-sounding name for that tune .... We were working
with Eleanor Bron on "Help!" and I liked the name Eleanor; it was the
first time I'd ever been involved with that name. I saw "Rigby" on a
shop in Bristol when I was walking round the city one evening. I
thought, "Oh, great name, Rigby." It's real, and yet a little bit
exotic. So it became "Eleanor Rigby".

'I thought, I swear, that I had made up the name Eleanor Rigby like
that. I remember quite distinctly having the name Eleanor, looking
around for a believale surname and then wandering around the docklands
in Bristol and seeing the shop there. But it seems that up in Woolton
Cemetery, where I used to hang out a lot with John, there's a gravestone
to an Eleanor Rigby. Apparently, a few yards to the right there's
someone called McKenzie.

'It was either complete coincidence or in my subconscious. I suppose it
was more likely in my subconscious, because I will have been amongst
those graves knocking around with John and wandering through there. ...
So subconscious it may be -- but this is just bigger than me. I don't
know the answer to that one. Coincidence is just a word that says two
things coincided. We rely on it as an explanation, but it really just
names it -- it goes no further than that. But as to why they happen
together, there are probably far deeper reasons than our little brains
can grasp.'
