Hi pcjr, have started looking today. Went through Nuneaton Parish Church records from 1901 to 1940 and came up with only the following
Mary Ellen Smith aged 40 of 5, Bridge Street, Nuneaton buried 6 January 1906
Louisa Ellen Smith aged 69 of 52, College Street, Chilvers Coton, buried 19 March 1920. That must be somewhere near.
John Smith aged 69 of Sunnydale, High Street, Nuneaton, buried 31 October 1918.
I also trawled through Attleborough Parish Church burials from the same period without success.
I will check Coton tomorrow.
I would have thought you would have some idea of the years when they died and some clue as to where in the town they lived, havn't you any relatives who you could tap?
