Charles Carroll. The only Roman Catholic signer of the Declaration of Independence, Charles Carroll of Carrollton, lived in Maryland where, as a Roman Catholic, he was forbidden from voting and holding public office. However, the wealthy Carrolls moved in the highest social circles and entertained George Washington and the Marquis de Lafayette at their estate.
