AncestryDNA Timber Algorithm Effects On My Indigenous American Paternal Chromosome 9 Segments Shared With African Americans

 

I have 11 African American AncestryDNA matches that are also matches at GEDmatch.  They all match me with 8+  centimorgan (cM) segments on my paternal Chromosome 9 location 87605455 - 107932645.  23andme, AncestryDNA, Dr Doug McDonald's chromosome painting, and DNA Genics Admixture Studio's numerous admixture calculators/oracles show that the paternal chromosome 9 segment is Indigenous American. AncestryDNA Timber algorithm is affecting the Indigenous American Chromosome 9 segments shared between us. 


D. Babineaux, C. Henry, B. Guidry, and D. Dixon are my only paternal DNA relative matches that have roots in my father's home state Louisiana.   The common Indigenous American ancestor was living outside Louisiana.  D. Babineaux, C. Henry, and B. Guidry are closely related to each other, and they are Louisiana Creoles that are part Acadian.  They share AncestryDNA matches of Acadian ancestry with me. I am a 4th great grandson of a 3/4 Acadian woman. The vast majority of my paternal European American DNA relative matches have Acadian ancestry.  


Only T. Cooper has a familytree that has Indigenous American ancestors.  She has the most extensive familytree by far. 


W. Hanson's familytree shows that he has Lassiter ancestors.  There is a known European American Lassiter family that has Native American ancestry. Robert Lassiter received landgrants in Nansemond County, Virginia as early as 1672 and is thought to have been married to Prudence who was a member of the Nottoway tribe in Virginia. W. Hanson and I share M. Lassiter as an AncestryDNA match, and her father was a Lassiter.  There is a Lassiter man that matches me on my paternal Indigenous American Chromosome 6 segment at FamilyTreeDNA, and my father's maternal half sister Carrie matches me on that segment and the European segment that is next to it.  Therefore, the European segment and Indigenous American segment on my paternal Chromosome 6 come from my paternal grandmother Mary Alice Gaines and not my paternal grandfather Nolan Scott. The European segment comes from a Swiss Kinsey (Kunztli) family that immigrated to New Bern, Craven County, North Carolina in 1710 with most of them killed by Tuscarora Native Americans in 1711. None of the aforementioned families were ancestors of Grandma Mary's European American maternal Great Grandfather/my 3rd Great Grandfather who was one of the sons of English American plantation owner Benjamin Cross born in Gates County, North Carolina and 3/4 Acadian woman Anastasia Bourgeois born in Assumption Parish  in the Acadiana region in Southern Louisiana.  They have to be the ancestors of at least one of my enslaved African American paternal 3rd great grandparents. All of my paternal 3rd great grandparents were enslaved African Americans in Southern Louisiana with the exception of my paternal European American 3rd Great Grandfather.  

The names of 3 of my 15 African American paternal 3rd Great Grandparents are unknown. The names of only 4 of my African American paternal 4th Great Grandparents are known.  The lack of knowledge of my paternal African American ancestors factors in over 99.9% of my paternal African American DNA relative matches being unidentifiable. 


AncestryDNA's Timber algorithm has been revealed to have affected the shared Indigenous American segment matches.  There is no telling how many of my shared paternal Native American segment AncestryDNA matches that I really have. Some might include European Americans and not just African Americans.  Without a Chromosome browser, I don't know if the shared non-GEDmatch DNA cousin matches that I share with my 11 GEDmatch/AncestryDNA matches are matching through shared Indigenous American chromosome 9 segments.


Between me and my 11 African American GEDmatch/AncestryDNA relative matches with shared Indigenous American chromosome 9 segments:

1. M. Comer shares 10 matches with me at GEDmatch but only 2 matches at AncestryDNA

2. S. Blocker shares 10 matches with me at GEDmatch but only 2 matches at AncestryDNA

W. Hanson shares 10 matches with me at GEDmatch but only 2 matches at AncestryDNA

D. Babineaux shares 9 matches with me at GEDmatch but only 2 matches at AncestryDNA

J. Walker shares 8 matches with me at GEDmatch but  0 matches at AncestryDNA

T. Cooper shares 8 matches with me at GEDmatch but 0 matches at AncestryDNA

T. Henderson shares 8 matches with me at GEDmatch but 0 matches at AncestryDNA

C. Dawson shares 7 matches with me at GEDmatch but 0 matches at AncestryDNA

D. Dixon shares 6 matches with me at GEDmatch but only 3 matches at AncestryDNA

B. Guidry shares 6 matches with me at GEDmatch but only 2 matches at AncestryDNA

C. Henry shares 6 matches with me at GEDmatch but only 2 matches at AncestryDNA

Learning About My Paternal 2nd Great Grandmother Mary's Family And Their Connection To the Kinseys

I learned that the Kinseys were ancestors of my paternal grandmother Mary Alice Gaines' maternal grandmother Mary.  I found out that some of AncestryDNA that Aunt Carrie and I have are descendants of 2nd Great Grandma Mary's niece Susan Thomas. They have Kinsey descendant matches that they share with Aunt Carrie and me.  I found out that Grandma Mary Alice Gaines descended from a Swiss Kinsey family that immigrated to New Bern, Craven County, North Carolina in 1710. Their descendants.went to Jones County, North Carolina and Colleton and Barnwell Counties in South Carolina. Aunt Carrie has over 100 AncestryDNA matches that are descendants of this Swiss Kinsey family.  They're descendants of John Ripley Kinsey (b. 1698) and Mary Isler. She, two European American Kinsey descendants, and a man in Switzerland match each other in the same location on Chromosome 6. https://diversegenes.blogspot.com/2023/07/discovery-of-swiss-immigrant-ancestors.html I found out that Grandma Mary...

My Patrilineal 2nd Great Grandfather William's Paternal Daggs and Maternal Smith Ancestral Families

William Henry Daggs Sr. and Mary Smith were the parents of my patrilineal 2nd Great Grandfather William Henry Daggs Jr aka William Scott.  They lived in Assumption Parish and Lafourche Parish which are in the Acadiana region which is located in Southern Louisiana.  They were recorded as Daigle in Census records, but they were not related to any Daigles of Acadian ancestry. 2nd Great Grandfather William wasn't even recorded as Scott in any of the Censuses.  The only record of him as Scott is his 1888 marriage record with my 2nd Great Grandmother Maria Lilly.  He was recorded as having the last name Dag-- (the last two letters hard to make out) in 1900 Census along with my 2nd Great Grandmother Maria and their children Pinky, Matthew, and Ivory (my Great Grandfather). He was recorded as having the last name Daigle in 1910 Census with my 2nd Great Grandmother Maria. He was recorded as Daggs in 1920 Census. He divorced my 2nd Great Grandmother Maria before 1920 and marri...
