Elm Ridge Cemetery is on Route 27 in North Brunswick, New Jersey. It is a historic cemetery of both the Colonial period (18th-century) and the Victorian period (19th-century). Although located in Middlesex County, the majority of the burials are from Somerset County, which directly borders the cemetery.HistoryPrior to 1868, the cemetery was an informal burial ground on the farm of John Van Cleef. It was near where Six Mile Run, a small stream, crossed historic King's Highway (now Route 27) in the historic community of Six Mile Run. The cemetery was associated with the Church at Six Mile Run, which was located there from 1710 to 1766 when it moved to its present location approximately one mile south.The Elm Ridge Cemetery Company was formed in 1868 by an act of the State of New Jersey authorizing the company to purchase an adjoining 5acre tract, to improve and operate the cemetery, sell burial plots, and be exempt from taxation as long as the land was used as a cemetery. The act named the initial seven members of corporation that would manage the cemetery, specified that all future members must be owners of burial plots within the cemetery, and that a new board would be elected annually by vote proportional to the number of plots owned. The act also specified that family gravesites in the old cemetery could continue to be used for burial by the respective families.
