The Countess Magri was the most famous person ever to stay at the Hotel de Paris in Georgetown.
The countess, probably better known as the former Mrs. General Tom Thumb, appears to have been the most famous person to sign the guestbook in 1893, anyway. Before she married Count Magri, an Italian, the countess was well known in popular American culture. She and her husband were internationally known through the marketing and promotion efforts of circus master P.T. Barnum.
