Manitas, You/Wikipaedia could very easily be correct.
The City of London Cemetery however was not carved out of Epping Forest it was part of a huge privately owned estate, the name of the one time owner of which escapes me at the moment I am sorry to say.
The other cemeteries which you mention are all close by me. I have close relatives over five or more generations in all of those mentioned except the Jewish Cemetery at Plashet.
