The Ross Cemetery was outside of Masontown in Gray's Landing. In the early 1900's, when a coke plant and railroad tracks were being built in Gray's Landing, the remains of the Rosses were removed from the McClain graveyard, adjoining the Ross farm, and reinterred in a section of the Masontown Cemetery known as the "Ross Cemetery." It was called this because that portion of the Masontown Cemetery once was part of the John Ross Farm in Masontown, inherited from Robert Ross. The ground was sold for a cemetery by the owner, John Ross.
