John Cornish - Christow

[petercornish]

Hi,
JOHN CORNISH, Captain and his brother Frederick, Agent of Frank Mills Mine, Christow lived in adjacent cottages at Canonteign House, according to 1871 census.
FREDERICK died of typhoid in 1873 and I have this well documented.
JOHN'S wife is recorded as 'widow' in 1881 living with her family in  Liverpool but I have been unable to trace JOHN'S death from national records.
Can some kind person look up local records for details of his death and burial.
