The McMillan farm is on West Confederate Avenue not far south of town. (Tour map: West Confederate Avenue Pt. 1) It included extensive orchards both north and south of the house, and a woodlot known as McMillan’s Woods to its southwest. The twenty acre apple orchard notheast of the house was the largest orchard on the battlefield.
David McMillian, born in 1800, lived here at the time of the battle with his children Adelaide, Laura, Caorline and Oscar, who ranged in age from 18 to 24.
On July 1 General Reynold’s Union First Corps marched across the woods to the west of the house on a shortcut that took them from Emmitsburg Road to the west side of Gettysburg. On July 2 and 3 the ridge on both sides of the house held several Confederate artillery batteries that dueled with their Union counterparts on Cemetery Hill.
The house today has been extensively changed since the time of the battle and is a private residence. The twenty acre apple orchard is being replanted by the National Park Service.
