GEDmatch is a public DNA and genealogy database now run by Verogen. It lets people upload DNA from testing companies to compare family lines and also supports forensic investigations, a mix that has drawn privacy and regulatory scrutiny.
DNA testing and archival sleuthing have identified Pvt. John Pumphrey, a Continental Army private killed at the Battle of Camden in 1780, ending decades of historical anonymity just before the United States marks its 250th anniversary.
