Birthdates from 1939 Register
Of Granville Road, Sidcup.
Death Dates from Ancestry to double check details as the stone is very hard to read.
By the 1960s most internments at St.Johns were ashes and unless they were on an older burial plot they were not always entered in the Church burial register, I could not see an entry for Dorothy or Herbert.. This stone could also be in memory only but is in the section of the Churchyard used for Ashes.
