Samuel Vaughan was a English merchant. With his wife Sarah Hallowell, duaghter of Benjamin Hallolwell of Boston, MA, Samuel had eleven children. Samuel lived in Philadelphia from in 1783-1790. His son Benjamin was a member of Parliament for some time, and afterward lived in America, where he was acquainted with Benjamin Franklin, publishing some of the latter's essays in 1779. Another son William pursued a life in commerce, with particular interest in the ports of England; in 1783 he was elected as a Director of the Royal Exchange Assurance Corporation. A third son, John Vaughan, was a Philadelphia merchant. He ordered a replica of Gilbert Stuart's portrait of George Washington from the artist; the painting was a gift to his father Samuel, an admirer of Washington. After Samuel's death, the portrait passed to William. It is now in the collection of the NGA (1942.8.27).
