About This Data
This ancestry composition is based on a 23andMe segment table (version 0.5), not a direct percentage report. Row counts are directional indicators, not precise percentages of genetic ancestry.
The Sub-Saharan African signal resolves to three historically specific populations: Nigerian (Yoruba/Igbo, Bight of Biafra), Ghanaian/Liberian/Sierra Leonean (Ashanti/Akan, Gold Coast), and Angolan/Congolese (Kongo Kingdom, West Central Africa) — the three dominant source regions of the transatlantic slave trade to the American South and Caribbean. The Senegambian signal (3 segments) reflects the earliest Atlantic slave trade corridor, where many enslaved Africans were already literate in Arabic and familiar with rice cultivation.
The European signal includes Spanish & Portuguese (7 segments) and Southern European (11 segments) alongside British/Irish and Northwestern European. In an African American profile, this Mediterranean/Iberian presence typically indicates either Louisiana Creole ancestry (French, Spanish, African, and Native American families who were free before the Civil War) or Caribbean-routed ancestry (enslaved people transiting through Spanish colonies before arriving in North America).
The Indigenous American signal (6 segments, ~1.7% by count) is supported by chromosome painting data showing 2.53% Indigenous American by base pairs on Copy 2. This does not establish a particular ancestor or tribal affiliation. The proposed connection through Gloria to the King households of Marion County remains unconfirmed; their geography cannot independently identify the source of these DNA segments.
The Filipino & Austronesian signal (2 segments) is unusual in African American DNA. The most historically grounded explanation is the Louisiana bayou Filipino communities: Filipino sailors from Spanish galleon crews established "Manila Village" in Barataria Bay, Louisiana in 1763 — the earliest documented Asian settlement in North America — and intermarried extensively with French Creole and African American families through the 18th and 19th centuries. If the Iberian/French European signal reflects Louisiana Creole heritage, this may be from the same geographic origin.
