Crumbling and structurally unsound, an inner staircase is now almost unrecognisable. In the following years, Arlington passed to Hurbert Barnum who purportedly presented it to his wife, Annie Barnham, as a wedding gift. Part of an affluent Natchez family, Annie was also the owner of the city's beautiful Monmouth mansion, however, she continued to reside at Arlington after her husband's death in 1939.
Annie is said to have diligently conserved the property and added to its prestigious collection of books by purchasing prized first editions, which she displayed in the library along with the other prized volumes.
