A short-lived town was built in 1691 at the confluence of Potomac Creek and the Potomac River on Potomac Neck. The town was abandoned by 1720, but six years later became the abode of John Mercer, who developed a plantation there. The site of his house was excavated by the Smithsonian Institution in 1956. Two small sherds of North Devon gravel-tempered ware were found there in a predominantly mid-18th-century deposit.

Elder, Jr., assistant curator of ethnology at the United States National Museum, has been investigating the site on the Chesapeake Bay of a plantation or small settlement known as Angelica Knoll. This investigation has revealed a generous variety of gravel-tempered utensil forms, including both 17th and 18th century styles. The range of associated artifacts points to a site dating from the late 17th century to about 1765. KENT ISLAND, QUEEN ANNE COUNTY, MARYLAND. A small collection of late 17th-century and early 18th-century material--gathered by Richard H. Stearns near the shore of Kent Island, a quarter-mile south of Kent Island Landing--includes both North Devon types. The collection was given to the United States National Museum. LEWES, SUSSEX COUNTY, DELAWARE: TOWNSEND SITE. The Townsend site was excavated by members of the Sussex County Archeological Society in 1947. This was primarily an Indian site, but a pit or well contained European artifacts, including a North Devon gravel-tempered jar (fig. 25). The village of Lewes, originally the Dutch settlement of Zwaanandael, was destroyed by the British, who occupied the area in 1664.[66] The European materials from the Townsend site were given to the United States National Museum. PLYMOUTH, PLYMOUTH COUNTY, MASSACHUSETTS: "R.M." SITE. A site of a house believed to have been Robert Morton's, located south of the town of Plymouth, was excavated by Henry Hornblower II. It contained North Devon gravel-tempered sherds. The collection is now in the archeological laboratory of Plimoth Plantation, Inc., in Plymouth. ROCKY NOOK, KINGSTON, PLYMOUTH COUNTY, MASSACHUSETTS: SITES OF JOHN HOWLAND HOUSE AND JOSEPH HOWLAND HOUSE. The John Howland house was built between 1628 and 1630; it burned about 1675. The site was excavated between September 1937 and July 1938 under supervision of the late Sidney T. Strickland.[67] Several gravel-tempered utensil sherds were found here, as well as a piece of an oven (see fig. 26). Artifacts from this and the following site are at the Plimoth Plantation laboratory.
