Shortly after the creation of the nation’s first municipal orphanage in 1790, the citizens of Charleston contributed generously to the construction of a large and well-documented edifice on Boundary (now Calhoun) Street that housed thousands of children between 1794 and 1951. The location of the institution’s initial home, visited by President George Washington in May 1791, is far less remembered, however. A search for clues to the location of Charleston’s first Orphan House leads to a forgotten Pinckney family property in the heart of Colleton Square.
