Enter the grounds through the memorial gateway, framed by two stone poillars, ereceted in 1925. Each pillar contains tablets that honor all who served in World War I, and the Donegl Society members who gave their lives in World War I. The dedicatory address was given by General Robert E. Davis, Adjutant General of the U.S. Army.
Headstones in the cemetery provide an amazingly well-preserved genealogical resource about the settlement and development of the Doengal area from the 18th Century through today. Burial plots continue to be availalbe to members of the Donegal Presbyterian Church. Special funds and donations are used to cover maintenance of the grave markers and keep the cemetery well-preserved and in good condition through the years.
The study house was built in 1810-1811 and over the years has been used for many purposes. At one time it was the caretaker's dwelling. It was remodeled in 1976, with careful attention given to preserving all historic aspects of the building and architecture, and dedicated as the William Kerr Study House in honor of Reverend William Kerr, pastor from 1807-1821. Today it houses the records of the Church and Society, the pastor's office, and meeting rooms.
The original Witness Tree was a stately white oak that grew and flourished for nearly three centuries, but sadly had to be replaced. The current Witness Tree was grown from the original tree, and stands in the same spot as a proud testimonial to the preservation of the Donegal Society and the Donegal Presbyterian Church. It was around the original Witness Tree that congregants gathered in 1777 to pledge their support of the fight for independence from British rule.
The spring at the foot of the hill was essential for members who made long journies to attend services. The spring water provided refreshment for the horses, as well as the congregation who would enjoy a midday meal between the morning and afternoon services prior to returning home.
Preservation of the grounds and grove are an important part of the charter of the Donegal Society. Many of the trees in this peaceful setting have been dedicated to the memory of early pastors and influential members of the Society. In the 1930's, work was started to develop a trust fund for the trees. MIss Mary Cameron, a descendant of Simon Cameron who was Secretary of War under Abraham Lincoln, was the first chairperson to oversee the preservation of the trees and grounds.
