My Y DNA Haplogroup Variants and The Evolution of the Y Chromosome

 This is a blog post about my Y DNA Haplogroup Variants and The Evolution of the Y Chromosome.


According to 23andme, my Y DNA haplogroup was first reported as E2b1 and then E-M85.  Therefore, I have an African Y Chromosome. I am not a patrilineal descendant of a European American. 

I did the Big 700 Test (it tests 700 markers) which led me to me being assigned Y DNA haplogroup E-BY101982. It is a branch of  E-CTS4257 which may have originated in South Sudan in 3800 BCE. My father was an African American born in New Orleans, Louisiana.  His father was Nolan Scott who was born in Thibodaux, Lafourche Parish, Louisiana. His grandfather Ivory Scott was born in Lafourche Parish. 

My earliest known patrilineal ancestor is my 4th Great Grandfather John W. Daggs. His enslaved wife Rachel and their children (Charles, Joseph, Eliza, Ellen, William Henry, Ann) were shipped to New Orleans from Alexandria, District of Columbia in 1835. William Henry Daggs Sr was my 3rd Great Grandfather and used the surname Daigle and lived in Assumption Parish and Lafourche Parish according to the 1870 and 1880 US Censuses.  William Henry Daggs Jr was my 2nd Great Grandfather and he is the first of my paternal line to use the surname Scott according to 1888 marriage record of him and my 2nd Great Grandmother Maria Lilly. He also used the surname Daigle in Lafourche Parish according to the 1910 Census. The 1900 Census showed that he was recording as having the last name Dag--(the last two letters were hard to read) in Lafourche and went back to using Daggs according to 1920 Census when he was married to his brother-in-law's sister. 

I am in Scott, Daigle/Daigre, and Dagg FamilyTreeDNA surname groups.

According to Haplogroup Story, my Y DNA E-BY101982 was formed in 850 CE when it branched off from the ancestor E-BY108741 with the most recent common ancestor estimated to have been born around 1100 CE. 







According to Globetrekker, my ancestral Y DNA haplogroup E-CTS4257 originated in South Sudan in 3800 BCE





I share ancestral Y DNA haplogroup E-CTS4257 in common with a man who lived between 1790 and 1850 CE during the Pre-Civil War Age and was found in the region known as Catocin Furnace, Maryland, United States. He was associated with the Enslaved African American cultural group.




My Y DNA Haplogroup variants/markers. 

 I checked them in FamilyTreeDNA Y Chromosome browser.  I searched The Genome Aggregation Database (gnomAD) browser.  It provides rsid number, kind of variant, the gene that it is in, allele frequency, and Combined Annotation Dependent Depletion (CADD) score.

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 ...

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...
