Robert Schofield Diggle & Frederic Diggle (organist)

I am looking for information on my father and grandfather.
Originally from Lancashire my father Robert Schofield Diggle
lived in Camden Town, London and was born in 1912.
My grandfather Frederic Diggle was a church organist and choir master and ended his career at Standish Parish Church. If anyone has any information on them I would be very grateful.
