"The progenitor of Divine Hymns, Joshua Smith (1760-1795), was a lay preacher affiliated with Baptist congregations in Caanan and Brentwood, New Hampshire. This book went through at least two dozen editions from 1791 to 1816. The titles of the editions varied, as did the collaborators and the publishers." - Music & Richardson, "I Will Sing the Wondrous Story", p. 138.
