Many people have helped materially with the story of Salona. Peter Maffitt, descendant of the Rev. William Maffitt, and Douglass and Henry Mackall, descendants of one of Maffitt's sisters, generously shared information on the Maffitt family and gave William Maffitt a three-dimensional shape. John D. K. Smoot, Jane Smoot Wilson and William Smoot, descendants of Jacob Smoot, recalled many stories of their family and of Salona. Clive and Susan DuVal, present owners of Salona, endured hours of interviews, photographing, and measuring of the house and outbuildings.

Valuable assistance has also been given by Mike Rierson, Fairfax County Park Authority, and W. Brown Morton, III, National Park Service, who contributed useful information on the architectural features and possible age of Salona; and William Elkjer measured and drew up floor plans of Salona. The Rev. William Sengel of the Old Presbyterian Meeting House, Jean Elliot, Frank Gapp, John Gott, Winslow Hatch, Beth Mitchell, and Donie Rieger also contributed information.

Librarians who have provided information and encouragement are Harva Sheeler, Dot de Wilde, and Eric Grundset, Virginia Room, Fairfax County Public Library; Mathilde Williams, Peabody Collection, Georgetown Public Library; the helpful staff at the Archives Division, Virginia State Library; and Ruth B. Lee, Historical Foundation of the Presbyterian and Reformed Church, Montreat, North Carolina.
