ISAAC B. DEXTER was born in Ohio County, Ky., July 25, 1843, and is a
son of Benjamin and Elizabeth (Warden) Dexter, both of whom were natives
of Ohio County, Ky., and of English-German and Irish-Italian descent
respectively.  Benjamin Dexter was educated and married in his native
county, where he has been engaged in agricultural pursuits all his life.
In early life he learned the blacksmith trade, which he followed in
connection with farming for many years.  In about 1880 he retired from
active life, but still makes his home on the old farm with his son
Joseph W.  He and wife have been from early life church members, he of 
the General and she of the United Baptist Church.  Mr. Dexter was born
December 19, 1806, and Mrs. Dexter the same year.  One of Mr. Dexter's
uncles, James Dexter, attained the unusual age of one hundred and
eighteen years, and made the first violin that was ever used in
Washington City.  Isaac B. Dexter received a good common school
education, and also attended college at Janesboro, Ill., for a time.
He was employed on his father's farm until he attained his majority,
soon after which he engaged in the saw-mill and lumber business,
continuing the same with abundant success until 1880.  He then came
to Butler County, Ky., and erected a grist-mill on Indian Camp Creek,
which he still owns.  The mill is doing an excellent business.  In the
spring of 1884 he opened a general store at the same place, where he
is doing a thriving business.  He carries a large and well selected
stock in his line.  He also owns a well-improved farm in [the] same
neighborhood of 240 acres, and is quite extensively engaged in
agricultural pursuits.  Mr. Dexter is yet unmarried.  In politics he
was formerly a Republican, but is now identified with the National
Greenback party.
