P. G. Wodehouse
Although wandering far away from the subject of the Saint himself, the name at least is preserved in the character of Lemuel Gengulphus Trotter, the Liverpudlian newspaper proprietor with a bad digestion and a face like a weasel, whose refusal of a knighthood prompts the following conversation in P. G. Wodehouse's Jeeves and the Feudal Spirit.
"...he shrinks, no doubt, from the prospect of being addressed for the remainder of his life as Sir Lemuel."
"His name's not Lemuel?"
"I fear so, sir."
"Couldn't he use his second name?"
"His second name is Gengulphus."
"Golly, Jeeves," I said, thinking of old Uncle Tom Portarlington, "there's some raw work pulled at the font from time to time, is there not?"
"There is indeed, sir."
