There is a published tree which may be referring to him.
Who were his parents? (I suppose though, as reply #3, you wouldn’t be asking his father's name if you had it
)
Born 13th February 1938, Huddersfield and died 2013 Leeds but no verification of death.
I can’t see that death in the indexes.
You might want to try a search of the 1939 register for that 13th February, but a different birth year. Also not Huddersfield nor Leeds, but Yorkshire.
There is a birth for K S 1936 Bradford and another for K S 1938, Huddersfield.
Paulo Leeds might have this info as only now asking for the spouse’s information.
As that is private along with children in the tree and no death date, we would have to presume she is still living.
