I think you may mean New Matamoras which is in the NE part of Washington County. The New Matamoras post office address probably covered a wide area. Each township in Washington County would have several cemeteries. There may be someone who can help you in Washington County or you might try to google New Matamoras Washington County Cemeteries.

Having been through New Matamoras many times, I can tell you that there is an Historical Society there......I'd, personally, call them to see what help/advice they could lend you.
