definitive conclusions can be drawn when multiple people from one family take
an autosomal DNA test, such as 23andMe, and
chromosome segments can be analyzed, compared, and triangulated. When
I received my maternal uncle John Reed's 23andMe results on April 4, 2015, I
immediately looked at his ancestry composition. To my surprise, over 80% of his
X chromosome was of Native American descent. I have since figured out that my
uncle received nearly all of his X-DNA from my great-grandmother, his maternal grandmother, Mary
Danner Davis (1867-1932) of Panola County, Mississippi. I also noticed that his ancestry composition included
0.5% South Asian DNA. At first, I contributed that to him having Native
American ancestry since certain forms of Asian DNA have been linked to Native
Americans. My theory turned out to be inaccurate. I have since discovered that
he inherited his South Asian DNA from his father, my maternal grandfather,
Simpson Reed of Tate County, Mississippi.
My Uncle’s 23andMe Ancestry Composition
Fast
forward to two months later. In June, I finally identified the father of my grandfather Simpson Reed’s mother, Sarah Partee Reed. She was born into slavery around 1852
on Squire Boone Partee's plantation in Panola County (Como). Significant DNA matches, oral history, and genealogy
research finally pinpointed Prince Edwards (born c. 1830) as being Grandma Sarah's
father. Grandpa Prince had been enslaved by William Edwards Sr., who was Squire Partee's
father-in-law and neighbor. It was common for an enslaved man to have a wife and children on a nearby farm/plantation. Along with that discovery was the DNA confirmation
of a brother of Prince named Peter Edwards (born c. 1835). Nearly all of Uncle Peter's 12 children settled in Oklahoma by 1920. This DNA discovery enticed more of Uncle
Peter's descendants to take the 23andMe test. (Others later took the AncestryDNA test.) Collectively, our DNA results have revealed some interesting things about our family history.
Presently,
four descendants of Uncle Peter Edwards have taken the 23andMe DNA test. Three other descendants of Uncle Peter recently ordered
23andMe kits! My mother and I, her brother and sister, their paternal first
cousin, and three second cousins make up the eight descendants of Grandpa Prince
Edwards who have tested with 23andMe thus far. Comparing our DNA in 23andMe with
the four currently tested descendants of Uncle Peter has revealed that my uncle
inherited that South Asian DNA from his great-grandfather, Prince Edwards. Here's how this was discovered.
Three matching chromosome segments between Uncle Peter’s great-grandson, Brian Edwards, and three of Grandpa Prince’s descendants were on sections where South
Asian DNA exists. In other words, Cousin Brian matches my uncle John Reed on
chromosome 2, from point 209 to 216 Mbp (6.3 cM). This section of their chromosome 2 is South Asian DNA. See diagram below. Cousin Brian matches my mother’s paternal first
cousin Armintha on chromosome 7, from point 3 to 20 Mbp (30.7 cM). South Asian DNA is on this section of their chromosome 7. Also, Cousin Brian
matches my mother and her sister on chromosome 10, from point 122 to 127 Mbp
(11.5 cM). All three of them possess South Asian DNA in this section of their
chromosome 10. This clearly indicates that they all inherited their identical South Asian
DNA from a common ancestor – one of the parents of Prince and Peter. Additionally,
all descendants, except two, had South Asian DNA in their admixture, from 0.1 to 1.8%.
Uncle
Peter Edwards’ great-grandson, Brian Edwards, shares a matching chromosome segment in his
yellow region (South Asian) of Chromosome 2 with my uncle, who is a great-grandson
of Prince Edwards.
To
be sure of the commonality of having South Asian DNA, I looked at the ancestry compositions
of many of my other 23andMe DNA matches of African descent. A small percentage
of people possess South Asian DNA. Therefore, having this DNA reflected
something. What was it? Did we have an ancestor from India or Pakistan? Or was
this South Asian DNA an indicator of something else? On my father’s side, I had
already become aware that ancestors from Madagascar, an island located 250
miles off the southeastern African coast of Mozambique in the Indian Ocean, may
transfer Southeast Asian DNA to their descendants. What about South Asian DNA?
T.L.
Dixon, a DNA scholar in the Malagasy Roots Project
Facebook group, confirmed that South Asian DNA may be an indicator of a
Madagascar ancestor. He further stated, “The range seems to be from 0% to 25%,
based on my family's Malagasy ancestors….You should also note the Southeast
Asian clusters very closely to South Asian (India subcontinent), so the algorithm
may show percentages in both categories.” Another DNA scholar, Teresa Vega, who
has also extensively researched her Madagascar ancestry, also explained that
she has both Southeast Asian and South Asian admixtures in her ancestry
composition. Her extensive research can be read HERE.

Of
the approximately 450,000 enslaved Africans who were transported to America over
the course of the transatlantic slave trade, only about 4,800 of them were from
Madagascar. That is much less than 1%. They were transported via 17 documented
slave voyages into New York and Virginia from Madagascar. Of that total, from
1719 to 1725, around 1,400 enslaved Africans from Madagascar were
disembarked into Virginia through the Rappahannock and York River ports.
Additionally, more were transported to
the Caribbean, especially Jamaica and Barbados.
In Exchanging Our Country Mark, Michael Gomez describes how those particular Africans transported into Virginia were "yellowish" in complexion and had hair like a "Madagascar's" (p. 41). Madagascar’s inhabitants are called the Malagasy people, and they speak a language by that name. Sources note that many of the Malagasy people possessed light skin and facial features very akin to people in Southeast Asia and Indonesia. Many others possessed darker skin and curly hair. Geneticists have determined that all of the Malagasy people descend from ancestors from Africa, as well as from Asia, specifically Borneo (Source). As time passed in America, Malagasy Africans were often and mistakenly labeled as “Indians,” or “Black Indians” or even “Native Americans.” Some may have even become labeled as “Blackfoot Indians.”

Interestingly,
my great-grandmother Sarah was rumored to have Native American ancestry. Even
one of her sons possessed “cold black,” curly hair that many considered to be a
Native American trait. Turns out, that was most probably a Malagasy trait, not
the Cherokee Nation.
