Ancestral DNA Tests Seemingly Wrong a Theory by James Lowrance

11223344_Geno LogoI’ve seen lots of videos and articles written by people saying the same type things regarding their Ancestry results not agreeing with their well-established family trees and ethnicities. This was actually the case with me as well but I completed two other tests in addition to the “Ancestry” company’s test. I also did the “23andme” and “Genographic 2.0 Next Generation” tests; the latter having the most impressive team of scientists and universities behind/conducting the DNA testing. What I was able to do was to compare all three and I did find very definite, unmistakable common threads. My crossover comparisons showed the Southern and Southern-ish parts of Europe such as France, Italy, Germany, Iberian (Spain Portugal) and Scandinavia. All 3 also showed me to have 2.0% Asian, each probably being Native American. Their own information states this regarding Asian people emigrating to North America at an ancient time period; mostly to The USA. Scientists are giving this lots of attention, this being the year 2017.
.
Most of these first major world countries I named above including France, were the Countries of “The Huguenots” (my ancestors) and their trek across Southern Europe, into Germanic countries, Scandinavia, to Wales England and finally for many, into The USA. These “Protestant Reformation” people fled from extreme persecution, while spreading protestant doctrine. My direct well-established ancestors; named in my family tree books compiled in the early 1960s, are named in the list researched by The National Huguenot Society. “Johannes Lorentz” and family is one of them – Late 1700s to early 1800s, listed by NHS, as being “Qualified Huguenot Ancestors”. He and his children are also named in our family tree books published approximately 50 years ago. Several of his children were the first to take-on my family’s present and permanent surname – “Lowrance”. In this sense the tests were very valuable to me, in gaining this confirming information but I feel time periods (different times of settlement and emigration) have much to do with the varied test results of these ancestral DNA companies. Example: The Nat. Geno 2.0 test shows me to be 45% British/Irish, while the Ancestry Company’s test shows me to be 75%. The Ancestry Co. is likely showing one snapshot time period while Nat Geno 2.0 is averaging several snapshot time periods in comparing my Genome to that of a huge number of other people.
.
For example, they may only be going back with a pool of DNA/Genome matches based on your Genome, from only 1 to 2 hundred years ago, this is going to show a lot of British/Irish. These countries were the last stops for so many European people before America branched-off and gained independence. If they go further back however, many people find they have Southern Europe, Eastern Europe, non-European countries, etc…, in their ancestral ethnicities. SO, My main point to this article regarding ancestral DNA testing companies, is that their analyses differ in many cases, due to how far back they go (100 to 500 years ago or even much more). So my advice is to cross-compare a couple or 3, or even more tests to get a better ancestral picture (try to include one that shows your “Haplogroups”). I realize this means the cost of your ancestry search will be somewhat more significant but the question is: “How important is it for you to know the most possible about your ancestral ethnicities that you can reasonably achieve?”
.
NOTE: I am not affiliated with any of these companies, in any way. I’m sure some people would disagree with my advice regarding being tested by more than one company. However, this is my honest opinion as to why they vary differently but likely significantly-accurate at the same time, within the snapshot time-periods each look at. National Geographic’s 2.0 Next Generation shows the most ancestral-ethnicity snapshots in my opinion and with the greatest scientific ancestry analysis. It did take me a while to understand that the different company’s genome pools they’ve collected (each have close to a million of them) – they compare these with yours/ours, which differ in the number of people they have collected samples from for different countries. They may look for somewhat more recent ancestry-ethnicities or for somewhat more ancient analysis comparisons.
