Thanks for the response,
I have a copy of the death register entry.
He died at Eastern General Hospital Leith, and usual residence was given as Beltonford Maltings.
Since my posting I have been in touch with my sister and she seems to recall that our mother saying it was a true blue (CoS) cemetery, using google maps I presume it would be the Queens Road cemetery.
I went to the parish church website and nothing is given with regard to the lairs and their locations within the cemetery.
I tried the East Lothian Council site but it only lists the cemeteries in East Lothian, there is no search engine to provide plot/lair references.
I'm awaiting a response to the message I sent to the East Lothian Council, and I will try the deceasedonline.com site.
Once again Thanks
George J. Smith
