My Filipino/Austronesian segment confirmed Malagasy

 

I have 23andme confirmation that my 0.1% Filipino/Austronesian that shows as one segment on my paternal Chromosome 9 is Malagasy in Madagascar.  


The Malagasy (French: Malgache) are an Austronesian-speaking African ethnic group indigenous to the island country of Madagascar. Traditionally, the population have been divided by subgroups (tribes or ethnicities). Examples include "Highlander" (ethnically Austronesian/Malay race-Indonesian with less Bantu ancestry) groups such as the Merina and Betsileo of the central highlands around Antananarivo, Alaotra (Ambatondrazaka) and Fianarantsoa, and the "coastal dwellers" (ethnically Bantu with less Austronesian ancestry) with tribes like the Sakalava, Bara, Vezo, Betsimisaraka, Mahafaly, etc. The Merina are also further divided into two subgroups. The “Merina A” are the Hova and Andriana, and have an average of 30–40% Bantu ancestry. The second subgroup is the “Merina B”, the Andevo, who have an average of 40–50% Bantu ancestry. They make up less than 1/3 of Merina society.[1] The Malagasy population was 2,242,000 in the first census in 1900. Their population experienced a massive growth in the next hundred years, especially under French Madagascar.


Countries with a significant Malagasy diaspora include France (specifically the overseas departments of Mayotte and Réunion),[11] Comoros (specifically the island of Moheli), South Africa, Latin America and the Caribbean and the United States.

The Malagasy diaspora in the United States includes those descended from people who, slave or free, came during the 18th and 19th centuries.[12] Other Americans of Malagasy ancestry are recent immigrants from Madagascar. Some notable Americans who have Malagasy ancestry include Andy Razaf, Katherine Dunham, Regina M. Anderson, William H. Hastie, George Schuyler and Philippa Schuyler, Muhammad Ali,[13] Robert Reed Church and Mary Church Terrell, Frederick D. Gregory,[14] Thomas P. Mahammitt,[15] Paschal Beverly Randolph, Maya Rudolph,[16] Claude McKay, Jess Tom, Ben Jealous,[17] and Keenan Ivory Wayans.[18]

Malagasy were also brought to Latin America, notably Peru, during the Transatlantic Slave Trade. A community of descendants of these Malagasy reside in Morropón (Piura), a city in northern Peru; the Afro-Peruvians of Malagasy descent number about 7,000.[19] Luis Miguel Sánchez Cerro, the Peruvian army officer who served as the 48th President of Peru from 1931 to 1933, as well as Interim President of Peru, was a notable descendant of this community. They call themselves Mangaches or Malgaches. This section of Piura is called la Mangachería.


The first recorded African slave in Canada, Olivier Le Jeune, was taken from Madagascar to New France in 1628.

My 23andme match with B. Portier is my confirmation.  I connected with him back in 2011, but I never knew how I was connected to him. I just knew that he was a paternal DNA relative match, and I had wrongly assumed that I was matching through a common West/Central African ancestor without checking out his Chromosome Painting.

He was born in France.  Both of his maternal grandparents and his paternal grandfather were born in France, but his paternal grandmother was born in Madagascar which was colonized by the French.





His 23andme Ancestry Composition/Chromosome Painting shows 1.2% Filipino/Austronesian and most of it is one long segment on Chromosome 9.



  

My 23andme Ancestry Composition/Chromosome Painting shows 0.1% Filipino/Austronesian, and it is all one segment on paternal Chromosome 9.





My Parental Inheritance shows that the 0.1% Filipino/Austronesian was inherited from my father.  My top chromosomes are maternal, and my bottom chromosomes are paternal.  





23andme Advance DNA Comparison shows B. Portier shares a segment on Chromosome 9 with me and no segments with my mother.  It is in the location where we have Filipino/Austronesian segment.



The matching segment is 5.19 cM  located at 71686476 - 77713279 on Chromosome 9  with 1,259 SNPs



Considering that his paternal grandmother was born in Madagascar and we share a Filipino/Austronesian segment on my paternal Chromosome 9,  I am confident that the segment that B. Portier and I share is from a common Malagasy ancestor in Madagascar. 


I found European Americans and African Americans sharing this same segment. 

One of the African Americans match me on just the Filipino/Austronesian segment

All the others match me on a segment that is mainly Sub Saharan African with the Filipino/Austronesian. 

One of the African Americans J. Mahoney live in New Orleans, Louisiana which is where my father Lawrence Nolan Scott was born.  All four of J Mahoney's grandparents were born in New Orleans. My paternal grandmother Mary Alice (Gaines) Simmons was a 6th generation Louisianan. My paternal grandfather Nolan Scott was a 4th generation Louisianan. 

At  GEDmatch,  I found three people that match my phased paternal DNA kit in the same location.  


B. Morrison     70984372 - 82080249     12.6 cM      1913 SNPs      

L. Campbell     70984372 - 81331339     11.2 cM      1799 SNPs 


B


Both B. Morrison and I have a E2b1 Y DNA haplogroup aka E-M85.  It is an African haplogroup that is rare in the Americas.

I did Big Y test from FamilyTreeDNA, and my Y DNA haplogroup is the refined E-BY10982 which is downstream of E-M85 which is upstream of E-M54.   I do wonder if B. Morrison would have E-BY10982 haplogroup is he tested.  I wonder if our shared Malagasy segment is a patrilineal segment. 

Y DNA haplogroup based off the Y Chromosome which is inherited from the father.

1 in 7,600 23andme customers have E-M85.




E-M54 has been found in 9% (3/35) of a sample of Malagasy from Madagascar.

B. Morrison and J. Morrison are African Americans. They show as 5th-8th Cousin matches to me with 9 cM across 1 segment. Both B. Morrison and J Morrison's AncestryDNA Estimate show 1% Vietnamese. My AncestryDNA Ethnicity Estimate shows no Vietnamese. AncestryDNA rounds off ethnicities to the nearest whole number percentage even though DNA doesn't work that way.




According to B. Morrison and J. Morrison's family tree,  their most distant known patrilineal ancestor is Luke Morrison who was born in 1784 in Virginia.  

My most distant known patrilineal ancestor is my 2nd Great Grandfather William Scott.  He was born with the surname Daigre in Baton Rouge, Louisiana in 1865.  Some time between 1900 and 1910, he changed his surname.

The Many Ethnic Groups and Languages of Africa - The Most Diverse Continent

This is a blog post about the ethnic groups of Africa which is a continent that consists of over 50 countries and has thousands of ethnic groups. What I have noticed about ethnic groups is that there no clear definition of what they are.  That's what I am noticing in countries in general. In regards to Africa,  I am seeing names of specific ethnic groups like Wolof, Mandinka, Fulani being listed for certain countries, and those ethnic groups are in multiple countries.  I am also seeing nationalities being listed for ethnic groups like Somali for Djibouti. I am seeing the continental backgrounds like African, European for Cabo Verde which is where my maternal grandfather's paternal grandparents immigrated to USA from when it was still a Portuguese colony. Of course, there is stuff like Bantu, Berbers, Arabs for ethnic groups I see color race names listed for ethnic groups like White for Saint Helena, Ascension, and Tristan da Cunha. The color race names make no sense any w...

My Paternal Grandmother's Descent from Swiss Kinsey Family Through A Branch of The Family That Had African Ancestry

Last year, I learned that my paternal grandmother Mary Alice Gaines descended from a Kinsey family that immigrated to New Bern, Craven County, North Carolina from Switzerland in 1710. She descended from John Ripley Kinsey who was born in 1693 in Switzerland.  He was one of the few of the Kinsey family that survived the Massacre of 1710 by The Tuscarora Indigenous Americans. The Kinseys were not the ancestors of Grandma Mary's maternal grandfather's European American father James P. Cross who was the son of  English American plantation owner Benjamin Cross who was born in Gates County, North Carolina and 3/4 Acadian woman Anastasia Bourgeois who was born in Assumption Parish in the Acadiana region in Southern Louisiana.  They had to be the ancestors of one of Grandma Mary's African American great grandparents.  All of them were slaves in the Acadiana region.   The only one of Grandma Mary's great grandparents that was recorded as being born in the Carolinas ...
