Am Desprate can any one help?

Am Trying to find my Grand farther His Name was Charles Arthur Breed B 1909 East Wymer Norwich .He was married to Minnie Grace Howman B 1909 Tredegar Bedwelty County of Monmouth, they had a son Named David Trevor Breed in 1933 ref 46 122.
The last image that my farther David Breed remembers of his dad Charles, is him walking of from the school gate David was aged 7, sad know.
But Davids Mother remarried a couple of years later to a Kennith Long, so they must have devoiced. I have search the BMD and cant find anything, no remarriage or death or kids,

Which would make him in his late 90's, even if he is not alive I find it hard to believe that David Breed was his only child, or that he never remarried.
This is my last chance if, I cant find any record of him he's either been abducted by aliens Ha! Ha!

Or immigrated can anyone help, any suggestions
