[Bourbon County]  [Paris City and Precinct]

DR. J. T. VANSANT, physician; P. O. Paris; was born in Fleming County,
this State; son of John K. and Nancy (Markwell) Vansant, both natives
of Kentucky.  The subject of these lines was raised on a farm until
seventeen, after which he received a collegiate course at Danville, Ky.,
and his medical education at New York City, graduating in 1877, at the
Medical College, and engaged in the practice of his profession in the
city where he graduated, remaining here until failing health induced him
to see another latitude, locating in Mt. Sterling, where he continued
practicing until October, 1880, when he came to Paris and succeeded Dr.
O. H. Buck, a homeopathic physician, who had a excellent practice.  The
Doctor has followed in his wake, and has been very successful in the
healing art, and made many friends, having established a lucrative
practice; is a member of the 1st Presbyterian Church, and February, 1882,
finds him a bachelor!
