A History of Kentucky Baptists, From 1769 to 1885, by J. H. Spencer, 1886,

River Association. Logan County.

JOHN B. DUNN, was a prominent and useful preacher in Gasper River
Association.  It is believed that he was a native of Logan county, and was
brought up amid its deep forests, at a period when the children of the
poor settlers had no opportunities to procure more than the elements of a
common English education.  At an early age he obtained hope in Christ, and
united with Center church, then under the pastoral care of William Tatum.
Here he was set apart to the ministry, not far from 1833.  About this
time, he moved his membership to Stony Point, having been called to
succeed that eminent old servant of Christ, Phillip Warden, in the
pastoral care of that church. He served this congregation eight years,
with  moderate success.  In 1835, he accepted a call to Hazle Creek
church, where he became the immediate successor of the famous pioneer,
Benjamin Talbot.  Here his labors were greatly blessed.  In 1838, a
revival prevailed, and the church increased from 59, to 182 members.  He
preached to this church seven years.  At the last named date, he became
pastor of Nelson Creek church in Muhlenburg [sic] county. He served this
church one year, during which about 10 were added to its membership.  In 
1837, he succeeded William Tatum in the pastoral charge of Mt. Pleasant
church, and ministered to it nineteen years.  The body numbered 56 members
when he took charge of it, and 172, when he left it.  His membership was
at this church, during most of the time he served as pastor.  In December,
1839, Mt. Carmel church, in Muhlenburg county, was constituted, and Mr.
Dunn was immediately called to its pastoral charge.  During the six years
he served in this position, the church grew from 14, to 46 members.  He
was pastor of Clear Fork church, in Warren county, and perhaps others not
named above.  In 1857, he resigned all his charges, and moved to the West,
since which, no account of him has been received.
