A History of Kentucky Baptists, From 1769 to 1885, by J. H. Spencer, 1886,
Rprinted by Church History and Archives, 1976, Lafayette, TN. Bourbon
County.

JOHN B. LONGAN was probably the ablest of the early preachers in Stockton
Valley Association.  In his boyhood, he came with his parents from
Virginia to Bourbon county, Kentucky.  Here he received a common English
education.  He united with the church in early life.  He had learned the
art of brick laying, but soon after he found hope in Christ, he began to
warn sinners to repent, with much zeal.  He was soon regularly ordained to
the ministery.  Shortly after his marriage, he moved to Barren county, and
settled near Glasgow.  Here he remained but a short time, when he moved to
the Cumberland river in what is now Monroe county.  This was about 1810. 
He gave his membership to Cumberland church, on the opposite side of the
river from his residence, in now Cumberland county.  He was called to
succeed Levi Rhoden in the pastoral care of this church, and was also
called to the care of Mt. Pleasant in Barren county.  To these churches,
and to the people in a large area of country around and between them, he
preached with acceptance and success about ten years.  Up to this time, no
such a preacher had labored in that region of the country.  In 1812, John
Mulky was excluded from the Baptists for having joined the Newlights, and,
the same year, Mr. Longan succeeded him as Moderator of Stocktons Valley
Association.  He held this position six years, and preached the
introductory sermon before that body, on at least three occasions.
     In 1821, he moved to Clay county, Missouri.  Here he took a leading
position among the ministers of the new State.  J. M. Peck wrote of a
visit he made, in company with Mr. Longan, to the Fishing River
Association, in 1824.  Speaking of the preaching on Sunday, he says: "He
[Wm. Thorp] was followed by J. B. Longan, and, for effefctive preaching on
such occasions, his equal had not then appeared in Missouri."  In this
field, he labored faithfully until the Lord called him to his reward,
about A. D. 1850.
     In his early ministry, Mr. Longan was a hyper-calvinist in doctrine,
but soon so modified his views as to call on all men to repent.  He had a
strong, melodious voice, which he used with great fluency.  He often wept
freely while he plead with men to turn to the Lord Jesus and be saved, and
his preaching went to the hearts of sinners, with mighty power.
