McNulty's other works include the novels Misther O’Ryan (1894), The Son of a Peasant (1897), Maureen (1904) and Mrs. Mulligan’s Millions (1918).
McNulty's other remaining play, The Courting Couple, was published by Gill, Dublin, posthumously, in 1944.
[1] McNulty is today most remembered, though, as an indispensable historical source used in both live interview and archive by biographers of the eminent Irish playwright and socialist, George Bernard Shaw, himself a founder of the Fabian Society.
41 pages of McNulty's manuscript recollections of Shaw, including copies of Shaw's letters to him, were obtained from McNulty's estate by the University of North Carolina, Chapel Hill and are housed in its Rare Book Collection.
[3] Shaw would drag his childhood soul mate, the ever accommodating McNulty, to Dublin's National Gallery, where the oddly matched pair (a very tall, thin and fair Shaw and the very, short, dark and pudgy McNulty), both precociously talented artists, would wander for hours studying the gallery's paintings, until they could recognize the technique of any Flemish or Italian painter of the human figure on sight.
