Music by Ernest Bucalossi and his father Procida usually published as being by "Bucalossi", so except in cases where the music was published before the former was born, it's difficult, as pointed out on Wikipedia, to be certain who wrote what. Ernest Bucalossi published some of his music under the pseudonym Ernest Elton, according to an article in 'The Gentlewoman' (19th November, 1904)
