Carroll, a distinguished Maryland planter-aristocrat, was one of two Roman Catholic signers of the Constitution... His public career included service in the Continental Congress, the Maryland senate, and the U.S. House of Representatives. He was also one of the first commissioners of the District of Columbia.
Daniel Carroll was a member of one collateral branch of a prominent Maryland family of Irish descent. The other was led by Charles Carroll of Carrollton, signer of the Declaration of Independence. Daniel's older brother was John Carroll, the first Roman Catholic bishop in the United States.
Daniel was born in 1730 at Upper Marlboro, Md. Befitting the son of a wealthy Roman Catholic family, he studied for 6 years (1742-48) under Jesuits at St. Omer's in Flanders. Then, after a tour of Europe, he sailed home and married Eleanor Carroll, apparently a first cousin of Charles Carroll of Carrollton.
...at the age of 65 he died at his home near Rock Creek in the present village of Forest Glen, Md. He was buried there in St. John's Catholic Cemetery.
