Part 880sr – Smith Robertson Genealogy – Updated Y-DNA Results – Haplogroup R-CTS7822

Good Day,

I have been reclassified. My Smith Paternal Line is R-CTS7822.

This means that as a descendant of ggg-grandfather James Smith my Y-DNA has gone from one of the more-common to just a little less-more-common… And this includes all male descendants of this Smith line, including the Lloyd Smiths, the Malin Smiths, the Landreth Smiths, et al, that is, if you can trace your ancestry back to great-great-great James Smith of Grenada.

Most recently I had two more SNPs tested – CTS7822 and F2863 with Family Tree DNA. That’s Single Nucleotide Polymorphism, SNP, pronounced snip; plural snips. SNPs are the most common type of genetic variation among people.

One test, F2863 came back negative and the other, CTS7822 came back positive. My Haplogroup classification at Family Tree DNA and at National Geographic’s The Genographic Project has now been changed to R-CTS7822. This is an adjustment from the previous R-L23 and this has something to do with the mapping of the YSC0000072, even though Family Tree DNA has me tested as negative for this SNP.

And what does this mean? According to Geno 2.0 of The Genographic Project each person is assigned to a specific Haplogroup. The Haplogroup is my branch on the human family tree… People belonging to the same Haplogroup can trace their descent to a common ancestor and even a specific place where that ancestor may have lived.

I am 1 of 678,632 participants of The Genographic Project. Accordingly 0.8% of all participants in the Project are included in my paternal Haplogroup and that includes 5,429 participants. As the Y-DNA is passed from father to son to son this means, once again, that all of ggg-grandfather James Smith’s descendants are of the R-CTS7822 Paternal Line.

As a member of one of the Y-DNA projects, the Bristol Channel DNA Project, the current update includes the following members with the Surnames which have tested positive for the SNP CTS78222.  These include Bennett, Coat, Follis, French, Locke, Peed, Robinson, Seymour, and Smith.

One of the project members has been running an analysis on our STRs (Short Tandem Repeats) and has calculated/estimated that our MRCA (Most Recent Common Ancestor) for our grouping may have lived somewhere between 950 AD and 1200 AD. This time frame may be subject to refinement as more kits (albeit persons) join this specific Project.

There is still one hell of a lot that I need to learn and understand. I’m a bit farther along, but I have only scratched the surface of the information. Images and certificates are published by Family Tree DNA and National Geographic The Genographic Project.

Stay tuned.

And the mosquitoes are biting tonight. Have to get me some bay-rum for the itch.

Enjoy,

Jim

Part 876sr – Smith Robertson Genealogy – Y-DNA Haplogroup R-L23 – Still Trying To Understand

Good Day,

Yes, I am still trying to understand my Y-DNA results. And it has been sometime since I have even touched my data and information.  My current and tested Haplogroup is R-L23 (R1b1a2a).

Here’s a quick rundown. According to Max Blankfeld of Family Tree DNA, there are 23 pairs of chromosomes: 22 pairs are what we call the autosomal or the recombining DNA. The 23rd pair is the sex gene. Paternity tests use the autosomal. Those are passed from both mother and father and "mixed" into the child, whether male or female. This mixture generates a new set of 22 pairs. This is the part of the DNA that a paternity test company uses.

The 23rd and final pair, the sex gene, is transmitted to the children. A male child receives X-Y, which is the father's Y-DNA and the mother's mtDNA, while a female child receive X-X, which means only the mtDNA from the mother. The Y received by the male son, is passed on to his son.  This son receives his mother's mtDNA, not the grandmother's. So, the Y-DNA goes down the line while the mtDNA does not, and the autosomal continues to be mixed as it progresses down and through the generations...

There are two different kinds of "transmissions" between the autosomal and the sex gene. Since the Y is transmitted from father to son, to grandson, to great-grandson....practically without mutations, this is the DNA that allows us to compare two males to find out if they descend from the same line.

A male child, and that includes me, receives my Y-DNA and that is the data that is revealed from my Y-sex gene, the part of me that I get from my father, Frederick Kenneth Lloyd Smith. This would mean that all the male Smiths, including the Lloyd Smiths, the Malin Smiths, the Landreth Smiths, et al, who are descended from great-great-great-grandfather James Smith all received the same Y-DNA.
The confirmed Haplogroup is R-L23; also written as R1b1a2a.

As you can see from the two ISOGG, 2010 and 2011, our R-L23 is the “Most common European R1b”.

There is a ton of work to go through and the study of genetics continues. Because my Smith Y-DNA is of the “most common European R1b”, and apart from having the most common name in the English language, I am continuing to investigate and delve into the testing. I have had some success and have been able to match 111 markers through Family Tree DNA to three/four other surnames: Ware; High/Robinson; and Seymour/Seymer.

I will carry on digging, and I mean drilling down, as tests continue to be added. Two outstanding tests are currently slated to be completed – CTS7822 and F2863. Theirs is still one hell of a lot for me to learn. Also I need to restart my search and research for the origins of our ggg-grandfather James Smith.

Enjoy,

Jim
