In 1861, the property would be purchased by Stephen DuVal. While DuVal did not make any additions to the house itself, he did build a tavern on the property, though it is no longer there. Like William Winfree, DuVal would not hold it for long before selling. In 1881, Magnolia Grange was bought by Emma Cogbill. Unlike her predecessors, her family would retain ownership of the property until 1969.
The name Magnolia Grange comes from the magnolia trees and boxwood gardens that used to surround the property. Both were destroyed during the Civil War. Magnolia Grange is notable in that it was one of the only brick houses in the county as of the time of its construction. It was added to the National Register of Historic Places in 1980.
