Bert,
I need to dig out the copy from a file when I can locate it. An old work colleague from Stepney wrote it out for me years back. She and her sister put their heads together to recall their version. When I find it I will post it here. I by the way am from Bow, the one on the east side of the River Lea.

Guest, re St Pancras. St Pancras Old Church is still in situ. I was unaware of the Dickens mention. It was almost certainly the occupants of the excavated graves that were removed to Wanstead to the huge City of London Cemetery at Wanstead (Little Ilford). This happened with St Lukes, Clerkenwell and probably other London Churches.
