Charles Carroll, also known as Charles Carroll of Carrollton or Charles Carroll III, was an Irish-American politician and plantation owner. He was the only Catholic, the wealthiest and the longest surviving among the signers of the Declaration of Independence. His personal wealth included a 10,000-acre estate which held approximately 300 enslaved people. He served as a delegate to both the Continental and Confederation Congresses and later became Maryland's first United States Senator. A Founding Father, Carroll was often referred to as the "First Citizen" of the American Colonies for the use of this as his pen name in his writings in the Maryland Gazette.
