DNA from the skull of an unknown Revolutionary War soldier reveals more than his name

After 246 years, DNA and genealogical sleuthing identified an unknown Continental soldier as Pvt. John Pumphrey from the Battle of Camden.
Records show the Maryland teen served with the 7th Maryland Regiment, marched with Washington at Valley Forge and likely covered some 1,000 miles before dying in 1780.
Relatives celebrated an emotional naming ceremony just ahead of the nation’s 250th anniversary, and officials are working to replace his "UNKNOWN" gravestone.
