Dave, I have that referenced to"History of Calvert Co MD"-Charle F. Stein, Author & Publisher, 1976. Described as the land at Upper Marlboro, where the first Presbyterian Church was built. Ninian gave this church a Communion silver, which was still there in 1976. The Church now being the Hyattsville Presbyterian Church. Being unfamiliar with the area, but a desc. of both Ninian and contemporary Alexander Beall such items inteest me. Charlie
