Identifying a Revolutionary Unknown Soldier at Camden

Last month the Independent newspaper reported on the identification of remains from the Revolutionary War using a relatively new method.

The story started on the battlefield at Camden, where on 16 Aug 1780 Gen. Cornwallis’s redcoats decisively defeated a Continental force under Gen. Horatio Gates.

The article says:

Archaeologists surveying the area in 2020 came across human bones protruding from the ground. Eventually, 14 sets of remains were identified — 12 of them Continental soldiers. The others were determined to be connected to the British side and were reburied at the battlefield.

The Richland County Coroner’s Office had worked with Texas-based FHD Forensics on modern-day cases and asked for their help.

The head of that organization is Allison Peacock. She and her associates use the immense databases of genetic code that have built up in recent decades to find unknown biological relatives for a range of reasons.

One of the American corpses was labeled “Camden 9B” as the second body retrieved from the ninth excavated burial.

The 12 Continentals were later reinterred [in 2023] with full military honors. Camden 9B’s headstone read: “UNKNOWN. REV WAR. BATTLE OF CAMDEN. AUG 16 1780.”

Meanwhile, samples from two of the soldiers were sent to Astrea Forensics in California for DNA extraction and sequencing. . . .

From a petrous portion of the temporal bone, a delicate structure behind the ear at the base of the skull, they successfully extracted DNA that generated [Camden 9B]’s entire genome. Peacock’s team then uploaded the data to FamilyTreeDNA and GEDmatch to trace three types of DNA matches: autosomal, X chromosome and Y chromosome.

“We got 20,000 matches to work with,” she said. “So, it was a lot to kind of comb through.”

Another clue was that when Camden 9B died, “the growth plates around his knees had not yet fully closed,” meaning he was still young.

The genetic markers found a match on the maternal line with Russ Hudson, a “retired federal agent in Gettysburg, Pennsylvania.” He offered to join the search in archival sources.

Ultimately, the team found records of a Continental Army private from Anne Arundel County, Maryland, named John Pumphrey. He was in the right age range and had a family connection to Hudson.

Pumphrey’s exact birthdate is unknown, but those growth plates suggest he was between thirteen and fifteen years old when he enlisted in the 7th Maryland Regiment on 6 Jan 1777. He could sign his name only with an X.

As Historic Camden relates, Pumphrey’s regiment served at Brandywine, Germantown, Valley Forge, and Monmouth. He reenlisted on 28 Feb 1779, as shown in the paperwork above. The regiment spent the brutally cold winter of 1780 at Morristown.

In April 1780, the Maryland Line was sent south. The last part of their travels was a brutal trek from Cox’s Mill, North Carolina, to Camden, South Carolina—a difficult route with little food available along the way. Then came the battle for one of the British army’s main inland garrisons.

The skeleton doesn’t preserve clues to how Pvt. Pumphrey died. However, his brigade was part of an especially brutal fight with the 71st Highlanders, and the bodies were found in that part of the field.

Research continues on another of the bodies from the Camden field that had surviving D.N.A.,  now known only as 11A.
