First, my thanks to everyone for their contribution but, with respect, there is little new.
Second, some background/further info. A recent brief 'accompanied' visit to the cemetery to find a family plot was when I noted headstones were not, so far as I could see, inscribed with a reference number so I had little chance of locating it.
(The grave I am interested in [ref 28/13] is for the Parker family).
As an ex member of M&LFHS I am aware of a book of MI's with a note of the first interment (Thomas Albert Parker) in July 1884, but I am also aware three other members of the family were subsequently buried in the plot but suspect only one of them was added to the headstone along with Thomas Albert.
Only viewing the headstone will confirm this, plus other words inscribed, hence my desire to view and take a photo.
