I am searching for death/burial information for my great great grandfather Thomas Prosser who died between 1891 and 1901

My US cousins (whom I have recently found) cite his death as 1898 at Kings Caple but cannot remember how they sourced this information

He was born in Breconshire, lived in Blaenavon most of his life and is still there in the 1891 Census with his wife Rachel

Could someone advise whether there are any burial records for the Kings Caple area from this time

Many thanks
