John Bumppo is mentioned by Philip José Farmer in Doc Savage: His Apocalyptic Life. Farmer claimed to have located the gravemarker of Fern Bumppo Root, whom he had identified as the mother of Esther Root (left unnamed by Ross Lockridge in his novel Raintree County). The gravestone named Fern Bumppo Root's parents as John Bumppo - whom Farmer deduced must be the son of Natty Bumppo - and Juno Cooke.
