Person Name: Unknown Hymnal Title: New Christian Hymn and Tune Book Author of "Glory to God, who deigns to bless" in New Christian Hymn and Tune Book In some hymnals, the editors noted that a hymn's author is unknown to them, and so this artificial "person" entry is used to reflect that fact. Obviously, the hymns attributed to "Author Unknown" "Unknown" or "Anonymous" could have been written by many people over a span of many centuries.
