When Logan died in 1751, he was succeeded by his son William, who continued faithful to the proprietary interests and carried on the Indian work. His son, Doctor George Logan, was the next proprietor during the Revolutionary period. Educated in England and Scotland, he traveled extensively in Europe; after his return to America he became a member of the Agricultural and Philosophical Societies and was elected a senator from Pennsylvania from 1801 to 1807.

During Doctor Logan's occupancy Washington, Jefferson, Franklin and many other distinguished[30] American and European personages were entertained at Stenton. It was Washington's headquarters on August 23, 1777, while he was on his way to the Brandywine from Hartsville. Ten years later, on July 8, 1787, he came again as President of the Constitutional Convention, then sitting in Philadelphia, to see a demonstration of land plaster on grass land that had been made by Doctor Logan.

Sir William Howe occupied Stenton as his headquarters during the battle of Germantown, October 4, 1777, and on November 22 ordered it destroyed, along with the homes of other "obnoxious persons." The story of its narrow escape is interesting. Two dragoons came to fire it. Meeting a negro woman on their way to the barn for straw, they told her she might remove the bedding and clothing. Meanwhile a British officer and several men happened along, inquiring for deserters, whereupon the negro servant with ready wit said that two were hiding in the barn. Despite their protests, the men were carried away and the house was saved, as the order to fire it was not repeated.

After Doctor Logan's death in 1821, Stenton was occupied by his widow, Deborah Logan, until her death in 1839, when it passed to her son Albanus, an agriculturalist and sportsman. His son Gustavus was the last private owner, as the house was acquired by the city and occupied as their headquarters by[31] the Colonial Dames, the descendants of the Logan family removing to Loudoun near by.

No account of the Colonial houses of Philadelphia would be reasonably complete which failed to include the home of Stephen Girard. Although of scant architectural distinction, it is of interest through its association with one of the chief outstanding figures of a city noted for its celebrated residents. It is a two-story hip-roofed structure, rather narrow but of exceptional length, taking the form of two plaster-walled wings on opposite sides of a central portion of brick having a pediment springing from the main cornice and a circular, ornamental window. As at Hope Lodge a broad plaster coving is the principal feature of the simple cornice. The windows and chimneys differ in various parts of the house, and the doors are strangely located, all suggesting alterations and additions. The central part of the house has casement sashes with blinds as contrasted with Georgian sashes with paneled shutters elsewhere, and all second-story windows are foreshortened.

Stephen Girard, a wealthy and eccentric Philadelphia merchant, financier, philanthropist and the founder of Girard College, was born near Bordeaux, France, in 1750, the son of a sea captain. He lost the sight of his right eye when eight years old and had only a meager education. Beginning a seafaring life as a cabin boy, he in time became master[32] and part owner of a small vessel trading between New York, New Orleans and Port au Prince. In May, 1776, he was driven into the port of Philadelphia by a British fleet and settled there as a merchant. Gradually he built up a fleet of vessels trading with New Orleans and the West Indies, and by the close of the Revolution, Girard was one of the richest men of his time, and he used his wealth in numerous ways to benefit the nation and humanity. In 1810 he utilized about a million dollars deposited with the Barings of London to purchase shares of the much depreciated stock of the Bank of the United States, which materially assisted the government in bolstering European confidence in its securities. When the bank was not rechartered, Girard bought the building and cashier's house for a third of their original cost, and in May, 1812, established the Bank of Stephen Girard. In 1814, when the government needed money to bring the second conflict with England to a successful conclusion, he subscribed for about ninety-five per cent of the war loan of five million dollars, of which only twenty thousand dollars besides had been taken, and he generously offered to the public at par shares which, following his purchase, had gone to a premium.
