I think this may be collecting different Charles Pinckneys, of which there were quite q few.
1.) Charles Pinckney (died October 29, 1758) was a noted South Carolina politician and colonial agent. He was also the father of two candidates for Vice-President and President. Pinckney was long prominent in colonial affairs, serving as attorney general of the Province of South Carolina in 1733, speaker of the assembly in 1736, 1738 and 1740, chief justice of the province in 1752–1753, and agent for South Carolina in England in 1753–1758. His second wife was Eliza Lucas.Charles Pinckney in Wikipedia
2.) Charles Cotesworth "C. C." Pinckney (February 25, 1746 – August 16, 1825) was an early American statesman of South Carolina, Revolutionary War veteran, and delegate to the Constitutional Convention. He was twice nominated by the Federalist Party as its presidential candidate in 1804 and 1808, losing both elections. He was the son of Charles Pinckney (see above) and Eliza Lucas Pinckney.Charles Cotesworth Pinckney in Wikipedia
