Why is the is the calhoun mansion in charlston named the calhoun mansion?

The Calhoun Mansion was built by George Williams after the Civil War. George Williams was a blockade runner that made a fortune off his neighbor's misery, therefore was an unpopular citizen in Charleston. In the early 1900's the house was owned by Patrick Calhoun who was a nephew of John C. Calhoun. John C. Calhoun was extremely well respected as was the Calhoun name. Charlestonians found it much more pleasing to refer to the house as the Calhoun Mansion instead of the Williams Mansion.
