PETER S. JEFFERSON was born in Cadiz, Trigg County, on November 21, 1847,
and is a son of Dr. Thomas B. Jefferson, whose sketch appears elsewhere
in this work.  Our subject's early education was received in Cadiz.  At
the age of fifteen he began to clerk for his brother William (now
deceased).  He remained with him for about three years.  He next clerked
for J. W. Chappell for about two years.  He then went to Clarksville, and
there acted as clerk in a warehouse for about seven months.  He afterward
returned to Cadiz, and has since been engaged in the grocery and liquor
business.  Mr. Jefferson was married on January 21, 1883, to Miss Corie,
daughter of Charles Baker, a son of one of the oldest settlers of Cadiz.
This lady was born in Princeton.
