GREEN CLAY SMITH, the third child of Colonel John Speed and Eliza Lewis
(Clay) Smith, was born July 2, 1832, and has had a distinguished career.
He, too, became connected with the legal profession, to which the Speed
family has furnished several illustrious members.  At the age of fifteen
he volunteered for the Mexican war in Colonel Humphrey Marshall's cavalry
regiment, and was elected second lieutenant of Captain James Stone's
company.  He graduated in Transylvania University in 1853, and, after
obtaining license as a lawyer, he practiced in Richmond and Covington,
Kentucky.  His strong mentality, his superior powers of reasoning and
his keenly analytical mind enabled him soon to gain prestige at the
bar; he was also a leader in political circles, having been elected to
the legislature in 1860.  He served until after the outbreak of the Civil
war, when he at once entered the Union service and assisted in recruiting
the Third Kentucky Cavalry; was offered the position of major in that
regiment, but was appointed colonel of the Fourth Cavalry and commanded
that regiment until 1862, when he made brigadier-general and placed in
charge of a brigade of cavalry in Rosecrans' army.  He was brevetted
major-general in 1863 and the same year was elected to congress and
later re-elected.  After the war he was appointed governor of Montana,
and in 1876 he was the Prohibition candidate for the presidency of the
United States.
     Abandoning his chosen profession he entered the ministry and for
nine years was moderator of the general association of Kentucky Baptists,
affording a rare example of a mind so equally balanced that it achieved
fame in the professions of law and theology, in war and in statemanship.
He married Lena Duke, daughter of James K. Duke, of Scott county,
Kentucky, and a grand-niece of Chief Justice Marshall of the United
States supreme court.
