Autosomal DNA results – Paternal Line

A few months ago, April to be precise, 23andme, ran a one-day sale in honor of DNA Day. It was one of those things that while it wasn’t in the budget or planned for, the sale price was so phenomenal that I couldn’t afford to not subject my parents to one more ancestral DNA test. 23andme’s $499.00 package which includes ancestral and medical testing was offered for, are you ready for this, $99.00. See what I mean about couldn’t afford to pass it up. Who knew when there would be another opportunity like this?


The main reason I was interested in autosomal testing is due to the stories of Native American ancestry on my maternal grandmother’s line. I figured this would be a way to prove once and for all whether there was any truth to the story. I’ll talk about my mother’s results on Georgia Black Crackers.

Unlike the previous DNA testing I had my parent’s do for yDNA and mtDNA testing, the sampling process for 23andme was different in that you spit into a tube instead of swabbing your cheeks. Daddy, of course did some more complaining. “I thought you had already tested my DNA.” “I can’t spit in that little thing.” and the last one was really funny considering he’s always spitting, “I can’t fill it up to that line.” With much cajoling, I finally got him to collect enough spittle, my opinion only as it was not to the mark, so that we could ship it off.

Due to the high volume of people that managed to catch the one-day sale, it took awhile after shipment back to 23andme for them to acknowledge receipt of the kit. Once receipt has been acknowledged, I always feel like a kid on Christmas Eve, constantly checking to see if results are in.

The month of May came and went and no results. In June, I went on vacation and when I returned part of the trove of genealogical surprises was that the autosomal DNA results were in. Even though I don’t have nearly the stories, etc. on my paternal lineage as I do on my maternal lineage, I had / have formed some hypotheses over the years. One is, there was very little miscegenation going on my father’s side of the family. Granted that hypothesis was developed based purely on the old pictures, etc. that I had seem of my ancestors. Well, daddy’s results tend to support that hypothesis. Dad’s results were 85% African, 8% European, and 7% Asian. Wow dad’s even higher than Emmitt Smith’s 81% African, shown on a recent episode of the American version of WDYTYA. When I told dad the results he just chuckled.

23andme also offers Relative Finder, which is another reason I was interested in the autosomal testing, as I keep hoping to come in contact with another descendant on one of my paternal lines who can perhaps help with filling in some of the details behind the dates and places. I’ve still not had any success in that area of my research. Relative Finder did provide me with possible 4th – 5th cousins but of the people that I’ve had contact with, there aren’t any familial matches that I can confirm / trace. Hopefully, in the future, there will actually be a match.

The Search for a Great-Grandfather, Ancestral DNA, Haplogroups, and Mali

Seems like so much has happened in the genealogical world during my ten year break. One of the most fascinating areas to me, that is big in the genealogical community, is the use of DNA to search for ancestors. And so it was with excitement, anticipation, and nervousness that I decided to have both my paternal and maternal lines tested.

First I should probably do a brief explanation of what ancestral DNA is and is not.

1. Ancestral DNA can not provide you with your complete family or tell you who your ancestors were.
2. Ancestral DNA can
  • Determine if two people are related
  • Determine if two people descend from the same ancestor
  • Help in determining if you are related to others with the same surname
  • Prove or disprove your family tree research
  • Provide clues about your ethnic origin
Two types of DNA tests are available, mtDNA and YDNA. mtDNA is passed from a mother to her children, both male and female, without any mixing. So, mtDNA shows your mother's DNA, her mother's DNA and so forth back through the generations. Y Line Test tracks the Y Chromosome, which is only passed from father to son. YDNA tests can only be performed on a male descendant. Markers in both tests can be used to determine an individual's Haplogroup, which is a grouping of individuals with the same genetic characteristics.

There is also autosomal DNA, which as I understand it, is supposed to look at percentages of various groups that you descended from. If you need further information, check out Ancestral DNA 101, http://genealogy.about.com/cs/geneticgenealogy/a/dna_tests.htm, or just google ancestral DNA.
Testing and Results
I went through Ancestry.com and ordered the 33-marker test. At this time I decided not to do the mtDNA test on dad. Probably the only thing I've regretted in doing this is going through Ancestry. Not because Ancestry didn't do a good job with the testing but because their database is not the greatest. I chose them primarily because I was already a member of Ancestry, could link the results to the family trees I have there, and finally, price.

Although dad complained the entire time (don't know why you are doing this, all those people are dead), testing was easy. After receiving the kit from Ancestry, I took the 3 swabs that came with the kit, swabbed the inside of dad's checks, put the swabs back in envelope that was provided, dropped them in the mail, then anxiously awaited the results.

Haplogroup I1 - the Stonemasons
I received the results back much sooner than I expected and must admit I was surprised by the results. Dad's Haplogroup was I1 (formerly I1a) and the report stated that ancient ancestors primarily occupied what is now present day Norway, Sweden, Denmark and part of Finland. Not that I didn't believe miscegeny could have occurred, but if it did, unlike my other lines, there just didn't appear to be any identifiable physical traits of it. Of course that's purely conjecture as I never met my grandfather and am only going off the pictures I've seen of him.

Here is where the frustration with Ancestry's database comes in. Their database showed a really close match, within 3 generation of having a common ancestor in the last 70 years. I wrote this person not once but twice before realizing that the match hadn't checked in in over a year. Needless to say, I was a bit disappointed. I was so looking forward to possibly having more family members.

Sorenson Database and Mali
Thanks to a wonderful new genealogical networking site, Genealogywise.com, I've learned about other databases where I can take dad's results and manually enter them into their database.
So, last night, dad's results were entered into the Sorenson database. And the results are surprising given the Ancestry DNA report. My ancient ancestors more than likely came from present day Mali and our african surname is possibly Traore. Let's just say at the 85% match, ton's of names from Mali showed with the Traroe surname being the most common, etc. (23/25 markers).

What this Means to Me
I set about trying to determine who my great-grandfather (father of Harry Claudius Jones) was and that desire has not vanquished. Given the circumstances of my grandfather's birth, I suspect I may never find my great-grandfather. I won't give up on trying to find him but with regard to my Jones line, I finally feel like I'm starting to build a trunk to my tree even if I don't have names. It's the realization that I am no longer just part of a branch but something bigger than myself even I don't fully know what it is. It's being able to say, at least for now, my family came from Mali.

One of these days, when funds allow, I hope to retest through Family Tree DNA or another site that has a more extensive database than Ancestry, so that I hopefully can get in touch with possible relataives. In the meantime, I'll do further research on Mali and specifically the Traore family, and I also need to understand Haplogroup I1 more and its connection to that part of Africa.

Till Next Time!
