The Loudoun Restoration and Preservation Society this week gave $500 to each of 13 preservation groups working on a variety of projects including the restoration of Aldie Mill to a study of black history.

The groups, which have all received money from the society in the past, received additional funds totaling $6,500 Sunday at a picnic that included preservationists, county officials and Leesburg officials.

The society is a nonprofit group that raises money to pass on to those working to preserve "the best of Loudoun County's heritage," according to society President Catherine A. Boyd. The group has donated more than $185,000 to groups since 1973. Its principal fund-raiser is the annual August Court Days festival in Leesburg.

The society awarded money to the following projects Sunday:

The restoration of Aldie Mill, now in progress along Route 50 in Aldie.

The restoration of Christ Church in Lucketts.

The remodeling of Ford Store, now used as the Round Hill Town Office.

A study of Loudoun's black history by Hillsboro resident Louis Jett.

The restoration of the exterior of Mt. Zion United Methodist Church in Leesburg.

The restoration of the chapel of Leesburg United Methodist Church.

The restoration of the exterior of the Loudoun Museum.

The refurbishing of the exterior of the Lovettsville Museum and Library.

The effort by the Marshall Home Preservation Fund to purchase and refurbish Dodona Manor, the Leesburg home of Gen. George C. Marshall.

Upkeep of the four-acre formal gardens at Oatlands Plantation.

The refurbishing of an empty building for use as a visitor's center in Middleburg.

The restoration of a 1700s springhouse in Purcellville.

The effort by the Waterford Foundation to preserve the Village of Waterford and surrounding open space as a National Historic Landmark.

Besides giving money to these projects, the society presented framed prints of "Gray's Map of Leesburg," done in 1878, to Leesburg Town Council members Claxton Lovin and Christine Forester and County Supervisor Charles A. Bos (D-Leesburg). The maps will hang in the new town office at Market and Wirt streets and in the county administration building.

The society also presented a plaque to Loudoun Circuit Court Judge Thomas Horne, who was represented by Richard Kirk, his chief deputy clerk. The group gave Horne a plaque to thank him for allowing August Court Days staff and visitors to tour the courthouse during the annual event.
