The memorial stone stands at the junction of three rides in an area now forestry planted and was erected in 1857, marking the spot where George Allan and Margaret Gracie are buried. They were shot by dragoons as they fled from a conventicle at the Whig's Hole. The stone bears a long inscription giving details.

As the story goes Margaret Gracie, who bravely helped fugitives hiding in the hills and escaped five times from the dragoons and notorious persecutors, was captured at a field preaching. She was rescued by armed farmers before she, and a mysterious martyr called George Allan, were cut down in a volley of musket fire.
