Don't know if my last post made sense. What they would do, I think, is to take the historical information and reference it with a point or polygon on the map. When you use that data layer you would be able to query that point or polygon and you would be provided with the historical information pertinent to that point or polygon.
Anyway, Paul Schopp faxed this to Alan, it's from Waterways of Camden County.
May find more info at Camden County historical society?
Also, Alan posted to the Archeological Society of NJ list. There are some Native linguists there who may know, hopefully someone will answer.
All of these names are the same branch, and many of them sound similar when pronounced.
ATCO, ATCO BRANCH (Atquatqua Creek, Adcoadco Branch, Edquedque Branch, Jacs Bridge Branch, Jacques Bridge Branch)
This is one of the two principal streams, the other being the Batsto River which join at "The Forks" to form the Mullica River, alias Little Egg Harbor River or Atsion River. It rises near Rte 73 nw of Bishops and southeast of Berlin and flows east and southeast. It forms part of the eatern boundary of Waterford Township and thus of Camden County. Present topographic maps show this stream as Mullica River. Other maps use Atsion River or Little Egg Harbor River for all or part of the length of the stream. The use of theis stream as a county boudnary dates to 1709/1710, when old Gloucester County abutted Burlington County and the boundary between them ran (from the head of Coles Branch)"...upon a straight line to the southernmost branch of Little Egg-Harbor River..."(Patherson Laws, pp 2-4)
Prowell (p 1) gives the line as "...to near the head of Mullica River or a branch thereof known as Atco Atco...." Gordon's History of New Jersey p 262 describes Waterford Township as bounded by several branches of the Atsion River, of which Atquatqua Creek runs along the SE boundary." Barnes & Vanderveer, 1856 Map of Camden County (CCHS, M 83.90.646), shows the lower part of the stream as Little Egg Harbor or Mullica River but the upper reaches as Atco Atco.
The stream has had various other spellings recorded: Adcoadco, in the deed, Lippincott to Middleton, 8 May 1844 (Camden, A-63); Etquaatco, curvey, OSG, N-57 (1761).
It has been suggested by some writers that ATCO is an acronym based upon Atlantic Transport Co. If such a company ever existed, it is clear it had nothing to do with the use of "Atco" as the name of this stream and as the name of the town near its head, since the name had been in existence a century before the town of Atco was created by the Richards family (Family Empire in Jersey Iron, p 55); Boyer's Place Names (p 3) suggests the "railroad" may have had some connection with Atsion (which it eventually did) and the author conjures up a mythical Atsion Transport Company.
The earliest spellings suggest they were based on an Indian naming of this important stream. Prowell (p 262) states that Atco was "an Indian term for a place of many deer". It is curious that the 1953 Medford Lakes Quad shows a small tributary of the main stream, wholly within Burlington County and names it Alquatka. It originates in the West Jersey Cranberry Meadow. (See Sign Posts, p 2, where Bisbee spells it Alquatqua.)
At one time the main stream may have been called Jacs Bridge Branch. A deed from George Marple to Mahlon Marple, 12 Septemter 1766 (Colonial Deeds, X-108) refers to a "branch of Little Egg Harbor River called Jac's Bridge Branch alias (Edqueadque)". It would seem that "Edqueadque" refers to the main stream, Atco Atco. This is substantiated by references to "Jake's Branch" and "Jakes Bridge" in a deed from Samuel W Harrison, et al, trustees for George Marple to Martin Gibbs, et al, 18 June 1792 (Woodbury, O-292).
However, Jacs Bridge Branch has an identity of its own. West Jersey Title Company's Map of Voorhees Township (CCHS, M.83.117.1) shows a small stream, about half a mile in length, starting in the northwest angle of the intersection of Taunton-Hopewell Road with Jackson Road, at the locale called "Bishops" and runs east northeast to the main stream. The map names this little stream Jacques Bridge Branch.
"Jacques Bridge" is the bridge by which Cooper Road in Atco crosses the main stream to become the Atco-Kettle Run Road.
There is an interpretive trail at the Atlantic County Park in Estell Manor that is maintained by a boy scout troop that has portions of it posted along the trail.
