Eliza Shawnessy was the mother of Thomas Duff Shawnessy, a character in Raintree County by Ross Lockridge, Jr. T.D. Shawnessy claimed that he was the illegitimate son of Thomas Carlyle by Eliza.

In Doc Savage: His Apocalyptic Life, Philip José Farmer considers the various possibilities, but a combination of Carlyle's Calvinist personality, and that the fact that he would have had to impregnate Eliza whilst in his early teens, lead him to conclude that T.D. Shawnessy had not identified his father at all.
