Lawyers and Lawmakers of Kentucky, by H. Levin, editor, 1897. Published
by Lewis Publishing Company, Chicago.  Reprinted by Southern Historical
Press.  p. 184.  Bracken County.

MARTIN MARSHALL, born in Virginia in 1778, was a son of William Marshall,
who was a brother of Colonel Thomas Marshall and uncle of Chief Justice
Marshall.  William Marshall was a distinguished Baptist preacher,
prominent in establishing that church in Kentucky.
     Martin Marshall spent some years in Mason county, and in 1800
settled at Augusta, Bracken county, in the practice of law.  He refused to
hold office, and devoted himself exclusively to that practice.  He was of
studious habits, a good speaker, but not an orator, with a well disciplined
mind, broadened by a reading of general literature.  He is justly regarded
as one of the most eminent lawyers of the name in the state.
     His son, Thornton Francis Marshall, born July 4, 1819, entered the
legal profession in 1842, was elected county attorney for Bracken
county in 1851 and re-elected in 1855.  He served in the Kentucky state
senate in 1858, was a delegate to the Chicago convention of 1864, and,
like his father, was justly regarded as a pure and conscientious lawyer.
