Hi Plewsy,
These entries are taken from the Berks Burial Index (ex BFHS);
Tilehurst, St.Michael;
8-8-1975 Mary Agnes Dingwall (79), address - 32, Armour Hill, Tilehurst extra - Ashes
19-11-1977 Charles " (86) " " " " " "
Strangley I can't find any reference to them being cremated in the crematorium in Caversham.
Hope this helps.
