My Ancestor John Firthwrote"Experience & Gospel Labors of the Rev. Benjamin Abbott". (Benj. Abbott was one of the first members of the Methodist Church in the 1770's, when it came to Salem Co., NJ and later became a Methodist Minister).Rev. Abbott turned his writings (some of which are contained in the book) over to John, his longtime personal friend, shortly before his death.
This "Life" of Rev Benjamin was published by the Methodist Publishing House NYC and for many years was included in the course of reading for those preparing for the Methodist Ministry.
The text of the book was once on the Internet.I haven't checked to see if it still is.
