artist was running out of materials or that she was working at greater speed to complete commissions. Johnston usually signed her portraits on their wooden backing, noting her name, the location of completion, and the date of completion in order. A typical signature is the inscription on the reverse of her portrait of Philip Perceval: Henrietta Dering Fecit / Dublin Anno 1704. Johnston was almost exclusively a portraitist; the only landscapes attributed to her hand are the backgrounds of a pair of children's portraits from New York, which are also her only known portraits of children. About forty portraits by Johnston are known to survive; many have preserved their original frames and backboards, on which her signature may be found. These mostly depict members of her social circle and, later, of her husband's Charleston congregation, such as Colonel William Rhett. Many of her South Carolina portraits depict members of Huguenot families that had settled in the New World, including the Prioleaus, Bacots (including Pierre Bacot and his first wife Marianne Fleur Du Gue) and duBoses (including Judith DuBose). Today, a number of her works are held by the Gibbes Museum of Art in Charleston, which has developed an interactive online exhibition dedicated to her work; other pieces may be seen in the Museum of Early Southern Decorative Arts, the Metropolitan Museum of Art, and the Greenville County Museum of Art. Johnston is not known to have worked in oils, but one of her portraits was copied at some point by Jeremiah Theus. Nine portraits, each depicting members of the Southwell and Perceval families, were owned by American preservationist Jim Williams and displayed at his Mercer House in Savannah, Georgia. Seven are inscribed "Dublin, Ireland" and are dated from 1704 to 1705. They were put up for sale by Sotheby's in 2000, seven with their original frames. Williams protected them from the light in an upstairs dressing room where the shutters were kept closed.
