Unraveling Samuel Washington’s burial mystery
One of the most intriguing aspects of the recent genetic analysis is the unraveling of the burial mystery surrounding Samuel Washington, younger brother of President George Washington. According to Courtney L. Cavagnino, the lead author of the study, Harewood cemetery was the final resting place for multiple Washington family members, including Samuel and his descendants. Unlike his illustrious brother George, Samuel’s grave remained unmarked, possibly to deter grave robbers. The absence of headstones added a layer of complexity to identifying burial sites.

In 1999, researchers embarked on an excavation of unmarked graves at the Harewood cemetery, unearthing bones and teeth that held the key to unlocking this historical puzzle. However, initial DNA testing yielded inconclusive results due to degradation and contamination of the genetic material.
Advancements in DNA analysis proved to be pivotal in solving this mystery. By combining optimized techniques, researchers successfully extracted genetic material from the remains. Maternal relationships were determined through mitochondrial DNA sequencing, while Y chromosomes were utilized to identify paternal connections.
The genetic data revealed the deceased as Lucy Payne and her two sons, George Steptoe Washington Jr. and Dr. Samuel Walter Washington, Samuel’s grandsons. Of significant importance was the fact that the DNA of a living descendant closely matched that of Dr. Samuel Walter Washington, providing concrete evidence of their familial relationship.
This breakthrough not only identified the deceased individuals but also clarified which remains corresponded to each brother. Cavagnino emphasized the progress made in DNA analysis, highlighting how modern genetic techniques have enabled scientists to overcome previous limitations. The study underscores the importance of genetic analysis in unraveling historical mysteries.

Unraveling Harewood’s centuries-old mystery
After nearly a century and a half, the mysteries surrounding the identities of the remains disinterred from Harewood in 1882 have finally been unraveled. Cavagnino and her team utilized advanced DNA analysis techniques to examine the genetic material extracted from these historical remains.
The groundbreaking study, described as a “wonderful puzzle” by Connie J. Mulligan, a professor at the University of Florida, involved a meticulous combination of genetic data from deceased individuals and living relatives.
Samuel Walter Washington, the current proprietor of the Harewood estate, played a central role in the investigation. Surprisingly, his DNA showed significant similarities with the deceased brothers, a phenomenon attributed to pedigree collapse resulting from multiple cross-cousin marriages within the Washington family lineage.
Mulligan praised the study’s intricate dataset, which provided empirical evidence to understand how interrelatedness impacted kinship estimates. The study marked a significant milestone by producing George Washington’s first-ever Y-chromosomal DNA profile, offering invaluable insights into genealogical relationships among Washington descendants.
Despite the advancements made in unraveling these historical mysteries, the ultimate question regarding the whereabouts of Samuel’s grave remains unanswered. Charla Marshall acknowledged the possibility that his grave may have been exhumed long ago, leaving this aspect of the historical puzzle unresolved. While the findings provide unprecedented clarity, Samuel’s final resting place continues to elude discovery, adding a poignant layer to this enduring historical enigma.
