How many past generations does this test go back? Will it test going back a few hundred years?

The problem is that Ancestry is using an autosomal DNA test, which isn't very accurate beyond 4-5 generations or so -- and they even brag that this test is top-of-the-line, cutting-edge technology. This is a lie. The test performed by AncestryDNA is not accurate enough for genealogical purposes.

The results for Europe are also imprecise since there are no true German, French, Belgium, Danish, Polish population references that could represent where people resided 500 years ago. Download your Raw DNA results from ancestry and upload them to gedmatch.com which is free. Eurogenes will give you what you need. If it detects Amerindian in Eurogenes, it's detecting Eurasian since Europeans and Native Americans have that ancestry in common. For those Americans who suspect Native American ancestry, take Dodecad World9 Admixture. It is shows up on the pie chart, it's not noise, despite what others might say. Ethiohelix is for African Americans who want to know where in Africa their ancestors came from. see less The problem is that Ancestry is using an autosomal DNA test, which isn't very accurate beyond 4-5 generations or so -- and they even brag that this test is top-of-the-line, cutting-edge technology.

Yes it will. It is quite likely to confirm a match with most relatives to the level of third cousins, better than 50% chance of matching a true 4th cousin. You will get many matches with more distant cousins. The utility will depend somewhat on how many of your cousins have done tests, and you can learn more by testing more relatives. Ancestry has the largest database and many helpful tools for genealogy. To get the most out of it for genealogy will require a membership, but you can do a lot with the basic results.

Since Ancestry.Com updated their algorithm and chip In late 2018, I would say that the results now reflect very recent genetic ancestry. Before the update I had numerous regions (about 10 ) and most of the regions did reflect my genealogy as I know it ( a few were out there, but most made sense). But after this update I received just 2 regions; so more like broad brush strokes for me as opposed to my prior results which for me anyway, were more detailed and reflected some of my more distant ancestry .

Don't forget to take your raw DNA results from whatever company you go with an export them to the other sites, so you can find matches. Gedcom , dnaland, and geni.com for your family tree. You'll also get differing results with your raw data on other sites. But if you've got family on family tree dna or my heritage you'll not find them otherwise.

it is possible to detect autosomal DNA from the last 3 to 4 generations and possibly (in some cases) a little further, but this type of test rarely picks up anything beyond the fourth generation because of recombination. In other words, you might have a documented 4th or 5th great grandparent who is 100% Irish, but your results may not show any Irish, meanwhile your brother's test shows 2% Irish. So you still have Irish ancestry, but you apparently did not inherit their dna like your brother did(according to this test anyway)..

There is a lot of variation, but you could expect to find matches back to about your 5th great grandparents.

It can go back roughly 1000 years. Having said that, it’s a tool not an comprehensive answer. You can use it to see where the strongest representations for that dna is present day. This will give you a strong idea where to search for records. You can also speak to other DNA matches to help you along the way.

My husband, my 4 children, my half sister (well that half sister thing was a surprise, we thought we were whole sisters) and my half nephew are all on here. It seems to be pretty darn accurate in telling you who you are related to and can tell you if someone is close in family. I liked that I found people who were related to me who had family trees that went back generations and we were able to figure out exactly where my ancestors fit in and where they came from since 1806.

When I bought this test I was shocked to find that they do not include X, Y or mtDNA markers. For those interested, the 23andme test includes all three of those for almost the same price. You live and learn. What Sean wrote is correct, they include autosomal markers only.

The test will not tell you where your ancestors lived and when. It will tell you what regions in the world your DNA hails from. I know that probably sounds confusing. The reference groups consist of people who live in those regions today and have been there for many generations with no external mixing, if you know what… see more The test will not tell you where your ancestors lived and when.

So if you come from a long line of Germans, your results will probably show that you're all German, but it can't tell you who lived where when. Also, once you get to 5+ generations back (about 100 years), you may not inherit any DNA from some of those ancestors. But you may get distant cousin matches through great great grandparents. see less The test will not tell you where your ancestors lived and when.
