[1][2] Callcott was for some years organist of Ely Place Chapel, and was the composer and arranger of songs and glees.
Their son, Robert Stuart Callcott (1851-1886), showed great promise as an organist and musician but died in the spring of 1886 at an early age.
[1] Their daughter Emma Stuart Callcott married the Irish painter George Bernard O'Neill.
[3] Callcott published in 1836 an abridgement of his father's Musical Grammar, in 1840 a collection of psalm and hymn tunes for Edward Bickersteth's Christian Psalmody, and in 1843 The Child's own Singing Book.
[1] Callcott composed several songs, glees, and anthems, but his name was principally known by his arrangements and transcriptions for the piano, which amount to many hundred pieces.
