     Another distinguished citizen of Washington County was General MARTIN
D. HARDIN, the son of Colonel John Hardin.  He was a lawyer of great
eminence, and practiced his profession in Frankfort with distinguished
success.  He was a man of marked talent and very decided character, as
were indeed all the members of this family.  He was secretary of state
under Governor Shelby, and in 1817 was appointed by Governor Slaughter to
the senate of the United States, in which body he served one session.  He
was a major in the rifle regiment of Colonel John Allen, in the campaign
on the northern border during the last war with Great Britain, in which
situation he approved himself a brave, vigilant and efficient officer. 
General Hardin died at Frankfort in the fall of 1823.  He was the father
of the late Colonel John J. Hardin, of Illinois, who fell in the battle of
Buena Vista in Mexico.
