I have found reference to an abstract of a mortgage involving John Tunnicliff which refers to land in Waterford township in Gloucester County, Western New Jersey near the "Penshawkin" Creek which is dated 18 Aug 1763. The reference states this can be found at the NJDARM web site of the New Jersey Department of State, but I have yet been able to find it. Is anyone familliar with this document? The reference states it was "recorded in the Secretary's Office at Burlington in Liber N of Deeds, folio 25". I would be grateful if anyone knows anything else about this.
