Not a lost cause - at least not to find his death. You'll then have to do some legwork to find where he's buried, but we need to find the death first.
So when was the last time he was known to be alive? Was he at your parent's wedding, for example? If he had died before your mother married, when was her youngest sibling born?
Do you remember him at all? If you do, he must have died after you were born, and you might be able to pin down when you met him, e.g. by remembering what school you were at at the time.
E.g. if you know he was alive in 1974, then that's only 10 quarters of death indexes to go through, and it doesn't seem to be a terribly common name.
Does your mother have any aunts and uncles who may remember better when they last saw him? Do you have any aunts or uncles who might remember more?
I presume this is his birth: Q3, 1899, Marlborough, 5a, 91
