Another key component was DNA from a living descendant of Samuel Washington.
Samuel Washington, George Washington's younger brother, was buried in an unmarked grave at the cemetery at his Harewood estate (an interior view is pictured above) near Charles Town, West Virginia.
Fortunately for the authors of the new study, “DNA analysis has come a long way since the early 2000s,” Cavagnino said.
Further details came from 95,000 SNPs, an enormous volume of data targeting autosomal DNA (DNA that isn’t attached to sex chromosomes).
“The search for Samuel Washington’s grave is no longer underway,” Marshall said.
