I do a lot of genealogy and often see people posting on forums that they just got their DNA tests back and are shocked to see xxxx ethnicity. But, the results are only rough guesses that are only as good as their testing pool. (If you test for health genetics at 23&Me, the results should be accurate though.)

I tested at Ancestry and uploaded my results to FamilyTree DNA and GEDMatch.
  • Ancestry says that I am about 90% Irish, Scottish, English and German (they break it down more), about 4% Scandinavian, and the rest trace stuff. This matches with the paper genealogy work I've done and I have DNA cousin matches to all these branches of the family.
  • FamilyTree DNA says that I'm 89% British Isles and 6% Iberian (Spanish and Portuguese). No German. However, some of my most recent immigrant ancestors were from Germany. Also, I am descended from Mennonites who were almost exclusively German. As I said, I DNA match to cousins in these branches, so the lack of German in the FTNDA results cannot be correct. But if I hadn't seen the Ancestry results, I might be shocked by FTDNA.
  • GEDMatch has nearly a dozen different testing pools I can compare against and the results are all different. One says I'm nearly 14% Russian and more than 11% Mediterranean. I expect to see some traces of non-Northern European mixed in--after all the Ottoman Empire controlled much of Europe until after my ancestors started immigrating to the US--but those numbers are abnormally high.

People also often get quite excited about small, unexpected results: "I'm 1.6% Native American!" But anything under about 2% is just noise. Autosomal DNA just isn't that accurate for ethnicity results at that distance.

If you're strictly from an endogamous community, you probably already know this and DNA isn't going to tell you much more. The biggest group this affects is Ashkenazi Jews. Your results are going to say you're Ashkenazi Jewish from Germany, Central Europe, Poland, Russia, etc. and everybody has the same results. The tests just can't parse the results better for communities where people are strict about marrying within the community.

Claiming native ancestry was really common with white people for a long time, too, because they didn't want to admit they might have African ancestry. Part of my family is from the South. My DNA results tell me that I don't have African ancestry. But matches to distant cousins on Ancestry who are African American tells me I have an ancestor who's behavior I should be embarrassed by. I don't know who he was yet, but I'm sorry someone I'm related to was such an a-hole and assaulted women in that way.

For my son adopted from Guatemala it was amazing to get the results. We thought he was Hispanic/Asian. Turn out he is almost 100% Native American, in hi case Maya Indian. It really helped him learn more about his amazing heritage.

When I did my Big-Y700 test from FamilyTreeDNA they needed a very good sample .. the instructions said to lightly bite on the inside of your cheeks a bit, scraping it with your teeth .. and then to use the swab for at least 30 seconds ... as you swab move the swab up and down on the cheek while rotating the swap between your fingers .. this will get the best sample.

As far as the health report - you can use it as a tool to investigate further - but consumer DNA sequencing isn't the best. Talk to your doctor about any results that you are concerned about and they can get you some proper genetic testing done. Also remember that just because you have a marker - doesn't mean its activated ...

For those that did autosomal type tests at other companies (like AncestryDNA or FamilyTreeDNA's FamilyFinder test), you can download your DNA sequence in a file and upload it to https://promethease.com which will show you which DNA markers you have that match both postiive and negative health indicators.

Good tip! I knew you could download your results elsewhere for genealogy stuff, but I didn't realize there was a company that would do it for health markers.

They can't sell your data to anyone where you, as an individual, are identified. They might sell en masse, a bunch of data, but without your personal info attached. https://www.23andme.com/privacy/

Laws protect your genetic information. However, you can download your raw genetic data and run it through analysis elsewhere that is totally anonymous. Kind of fun to do. https://promethease.com/

And if you want to help catch unsolved murders and such you can submit your DNA to a public database. Who know? Uncle Bill might be serial killer! https://www.gedmatch.com/login1.php

I was pretty excited to find I'm more Neanderthal that almost everyone!

Zuleikaa, it was interesting to read your story! I'm a pale-ass white person and I've got some W. African in me.

We're all African though, since our species originated there.

The 23andMe lab was able to process DNA out of the second sample that I sent in. I guess the cheek scraping helped. The DNA is all processed and I just got my report back. I have not had much time to review it, but here are the bullet points:

On the ancestry side there were no real surprises. It says that I am 97% western European, with the strongest regions being within England, Ireland and France. I suppose if there is a surprise it was France and not the Dutch & German I had expected. However, the gene pool hits were from northern France (Normandy and near the German border). The report says that Louis the 16th and I share a common ancestor. That's an interesting tidbit.

As far as the African & native American blood ancestry that has been the lore of my mom's side of the family, the African part appears to be true. The report said that I have one relative from within the past 200 years with roots to the Caribbean island of Barbados and a little further back west Africa. But there was no Native American blood to speak of. That part of the family lore was just a tall tale. And like Nancy shared (post above), I have more Neanderthal DNA than most.

On the health side I have not had time to do anything but browse through the huge laundry list of potential risk factors -- but it is interesting to note that they nailed the top 3 on the list. Diabetes, hyperinsulinemia, and hypercholesterolemia. Check, check, check. I was surprised about how long the list of potential health issues was. But I am one who believes that we have some control over these risk factors by eating a good diet and living an active, healthy lifestyle. So I'm not going to lose any sleep worrying about it.

I've barely scratched the surface on my results. I find this stuff fun and interesting. I look forward to diving in a little deeper.

The French German border would move back and forth which I found out a few years back when I saw he was listed in the census here in TX as French but was probably born in Baden Baden Germany.

Early on when DH and I were still new in our relationship, he went off on a teasing little rant about "You Americans! Always talking about being 1/4 this & 1/16 that & 1/64 the other. Now we Germans, we're just German!" His mother overheard him, and said "You DO realize don't you that my maiden name is Czech?". Oops! He still thinks it a little funny that Americans are so preoccupied with their ancestors, but isn't so vocal about it anymore :-). I haven't had my DNA checked, and doubt that I will, but it does sound like an interesting delve into the past.

The tests are only sort-of accurate if all you're interested in is finding out an ethnicity break-down. It's entertaining, but not really solid science. They are good for getting health markers or for helping discover matches and getting through genealogy brick walls or if you're adopted and trying to find a bio-family. But the testing companies sell a lot of test kits on the premise that the ethnicities results are accurate. I guess they know they'd sell a lot fewer if their market was just people interested in the health stuff and genealogy nerds like me.
