Thomas Frost, was rector of St. Philip's Church, Charleston, and a graduate of Cambridge University, England, in 1780.
In 1832 he was U.S. District Attorney, but resigned his office because he could not conscientiously defend the constitutionality of the Tariff Laws.
Having already served several terms in the South Carolina State Legislature, he was elected by that body, in 1843, one of the judges of the Court of Common Pleas for life, but resigned the position, after a little more than ten years, on account of the great labor involved.
Frost afterward devoted himself mainly to the carrying out of the Blue Ridge Railroad enterprise, being for many years President of the road.
He cordially supported his State in her act of secession during the American Civil War, and died in the belief that she was right.
