The site, later referred to as the Anson Street African Burial Ground, was buried beneath the growing city and forgotten in the centuries that followed. The ethical treatment of these ancestral remains was of paramount importance to our community. Historically, narratives relating to the lives of African descendant people in Charleston have been inadequately documented and shared. For these reasons, we engaged the local African American community in a multifaceted memorialization process. Together, we sought to sensitively ensure that the Ancestors’ identities and lives were fully explored according to the collective descendant community's wishes. To this end, we involved the community in researching and celebrating the Ancestors’ lives through arts and education programs and analyzed their and community members’ DNA to elucidate their ancestry. Our engagement initiatives increased access for all ages to archaeological, historical, and genetic research and encouraged active participation in the design of a permanent memorial. The Anson Street African Burial Ground Project provides a successful example of community-engaged activist archaeology focused on honoring the Ancestors and their descendants.

The Gullah Society of Charleston, along with other Charleston community members, initiated a collaborative genomic study of these ancestors of presumed enslaved status, in an effort to visibilize their histories. We generated 18 low-coverage genomes and 31 uniparental haplotypes to assess their genetic origins and interrelatedness. Our results indicate that they have predominantly West and West-Central African genomic ancestry, with one individual exhibiting some genomic affiliation with populations in the Americas. Most were assessed as genetic males, and no autosomal kin were identified among them. Overall, this study expands our understanding of the colonial histories of African descendant populations in the US South.

The Charleston community facilitated a bioarchaeological and mitogenomic study to gain insights into the lives of these unknown persons, referred to as the Anson Street Ancestors, including their ancestry, health, and lived experiences in the 18th century. METHODS Metric and morphological assessments of skeletal and dental characteristics were recorded, and enamel and cortical bone strontium stable isotope values generated. Whole mitochondrial genomes were sequenced and analyzed. RESULTS Osteological analysis identified adults, both females and males, and subadults at the site, and estimated African ancestry for most individuals. Skeletal trauma and pathology were infrequent, but many individuals exhibited dental decay and abscesses. Strontium isotope data suggested these individuals mostly originated in Charleston or sub-Saharan Africa, with many being long-term residents of Charleston. Nearly all had mitochondrial lineages belonging to African haplogroups (L0-L3, H1cb1a), with two individuals sharing the same L3e2a haplotype, while one had a Native American A2 mtDNA. DISCUSSION This study generated detailed osteobiographies of the Anson Street Ancestors, who were likely of enslaved status. Our results indicate that the Ancestors have diverse maternal African ancestries and are largely unrelated, with most being born locally. These details reveal the demographic impact of the trans-Atlantic slave trade. Our analysis further illuminates the lived experiences of individuals buried at Anson Street, and expands our understanding of 18th century African history in Charleston.

They are comparable in terms of isolation, the objectification of leprosy sufferers and their association with religious charities. The Lazaretto on St Eustatius was operated from 1866 to 1923. The site was investigated to recover palaeopathological evidence of leprosy at a leprosarium in the Americas. Five burials were excavated; three individuals showed evidence of bone modifications consistent with those caused by leprosy, including aspects of ‘rhinomaxillary syndrome’ and the bilaterally symmetrical post‐cranial changes that have been described in leprosy examples from medieval Europe. An exceptional find was the presence of potentially leprous bone changes to the hyoid, thyroid and 3rd–6th cervical vertebrae.
