Yes, there are little ones in Heaven. T. B. Taylor. [Infants' Hymn.] This hymn appeared in the Protestant Dissenters Juvenile Magazine, 1833, and again in T. R. Taylor's Memoirs and Select Remains, 1836, p. 245, in 5 stanzas of 6 lines. It is found in common use in its original form; and also rewritten as "Children's voices high in heaven," in the Baptist Psalms & Hymns, 1858, No. 959, and later collections. The rewritten form of the text is by Mr. George Rawson, and was made for the Baptist Psalms & Hymns, 1858.
