Who was the last surviving signer of the United States Declaration of Independence?

Charles Carroll of Carrollton was the last surviving signer of the United States Declaration of Independence.

Carroll was a Maryland delegate and the only Roman Catholic signer of the Declaration. He was also one of the wealthiest men in the colonies and had become active in the movement for American independence before joining the Continental Congress.

He lived until November 14, 1832, dying at the age of 95. His death came 56 years after the Declaration was signed, making him the final surviving member of the group whose names appeared on the document.

Charles Carroll is sometimes confused with John Carroll, his cousin and the first Roman Catholic bishop in the United States. The signer was Charles Carroll of Carrollton, a name he used to distinguish himself from other members of the Carroll family. His long life allowed him to outlive every other signer.
