DNA analysis, initially utilized to trace the descendants of George Washington, holds promise in reconstructing the narratives of soldiers who served in some of history’s deadliest conflicts and reuniting their remains with their families. This intriguing potential stems from a study published in the journal iScience, conducted by scientists from the Armed Forces DNA Identification Laboratory (AFMES-AFDIL). Led by Courtney Cavagnino and Charla Marshall, the team identified the remains of George Washington’s great-grandsons, Samuel Walter Washington and George Steptoe Washington Jr., in fragmented and unmarked bones at Harewood Cemetery in Charles Town, West Virginia.

Now, researchers aim to extend these investigative techniques to locate the remains of servicemen scattered worldwide. “Our ability to analyze ancient samples, such as those from Harewood Cemetery,” explains Cavagnino, “enables us to refine methodologies for even the most degraded ossuaries. Our focus in this study was on unmarked graves at Harewood Cemetery.” The research team conducted a battery of DNA tests on the remains, complemented by genetic analysis from a living descendant of Washington. Surprisingly, the comparisons revealed closer genetic ties than anticipated, possibly owing to familial intermarriages in the president’s lineage.

“The methodologies we’ve developed,” concludes Marshall, “usher in new possibilities for positively identifying challenging cases, including missing soldiers across the globe. Securing a database of living reference relatives will be crucial in reconstructing the stories of those who perished in conflicts spanning from World War II to the Cold War, Vietnam, and Korea.”
