This is a great resource. Thanks to a collaboration between Gus Nichols and Joyce Tunstead, funerals conducted by J & C Nichols 1919-1936 are now available online. These are transcriptions of account ledgers. They list the name of the deceased and the address to where the bill for the funeral was to be sent.
They also note an approximate funeral date and where the deceased was to be collected from and to what cemetery/graveyard they were to be brought to. In some cases it also gives the age of the deceased.
Pre 1919 ledger are in the National Archives.
