Hi,
"Richard White Richards born St Just in Penwith about 1862, died 1924 in Ballarat East, Vic."
AND
"My hopes are that since Richard White Richards is one of the men who fit the profile (1861, Cornwall-1924 Victoria, Australia),"
Do you have the death certificate, dated 1924, in Victoria, Australia, of Richard White RICHARDS?
Without that certificate, you are only assuming that he was born in England.
He may have been born in Australia.
Mary
