"Washington D.C.'s original name was Rome, Maryland, and a branch of the Potomac River was called Tiber Creek, which was named after the Tiber river in Rome. Like Rome, Washington D.C. has 7 hills, whose names are: Capitol Hill, Meridian Hill, Floral Hills, Forest Hills, Hillbrook, Hillcrest, and Knox Hill. . .When the Congress, at the session held in October, 1784, at Trenton, New Jersey, enacted that a board of three commissioners should lay out a site, between two and three miles square, on the Delaware for a federal city, to be the capital of the nation, Daniel Carroll was named with Thomas Johnson and David Stuart as his associates. The choice of the present site of Washington was advocated by Carroll, and he owned one of the four farms taken for it, Notley Young, David Burns, and Samuel Davidson being the others interested. The capitol was built on the land transferred to the Government by Carroll, and there is additional interest to Catholics in the fact that, in 1663, this whole section of country belonged to a man named Pope, who called it Rome."
