I just watched a programme about trains in North Wales. One place they ended up was at the grave of John Ceiriog Hughes (1832-1887) in Caersws, He wrote his own englyn as an epitaph
Carodd fyw'n naturiol;
Carodd gerdd yn angerddol;
Dyma ei lwch, a dim lo
He loved musical words, he loved poets,
He loved to live naturally;
He loved a poem passionately;
Here is his dust, and no messing.
