I have a great grandmother who was fully German, of 4 siblings (myself and 3 others) tested, one got 12%, one got 4%, and two got 0% according to Ancestry's latest update. This shows how DNA does not divide evenly. Also, I have 2% Norway from 1 parent, who's lines are traced back mostly to 7th to 10th great grand parents with no trace of Norway or Norwegian sounding names. I figure it must be Vikings that settled in England or Scotland so far back there's no records.

Another excellent presentation delivered in a very clear easy to understand way.

I really enjoy your channel on this topic. You answer a variety of questions and you explain things well. I am confused about something. I was wondering if on the Chromosomes if the ethnicities that appear first on the line are the closest ancestors. Does length of line color determine how close and are far back in time. This might have to be another video too. lol

It feels like I stumbled into an advanced calculus class, but only got up to pre-algebra. I need a buffer course! 😁 But I watch your guys' videos everytime anyway!

My grandmother tested 4% middle eastern (she and her brother are half Southern Italian from Casaluce), and her brother, my great uncle tested on another site and it said that same 4% that he shares with his sister is Jewish. I got just over 3% of that, and my son got over 2% of it. Myheritage gave my son 12% Iberian, and 23andme initially gave me 12% Italian. My grandmother's paternal line is Messina. I did a lot of research on our Messina name, and it came from Messina Sicily. Messina Sicily was Messenia, and was named for the Mycenaean/Messenians who were given that area by the Italian govt. as their new home and refuge. They had fled from Greece during their last uprising against their Greek warrior slave masters. I saw an Very interesting documentary last week about the Philistines and the Caananites, and it was found that the Mycenaeans were the Philistines and Caananites. The Bible says that Israelite men were aloud by God to take wives from other nations as long as they accepted and worshipped God and rejected their fake gods. And the archaeologists found that the men of Israel had taken Caananite and Philistine wives. Samson had done so. I wonder if that is the secrets of the vatican... 🤔 Why no one knows true history...

I just found out I'm 43% indigenous American-Mexico, 31% Spainard, 7% Portuguese, 6%Basque, 3% French, 2% Jewish peoples of Europe, 1% Scotland, and 1% Ecuadorian! I wish I could figure out exactly who was What in my family lineage

Nicely done. There's one other complication. When you get back 5 generations or so you start running into the possibility that your family tree folds back on itself. My wife has a pair of ancestors who are gg on her mothers side and ggg on her fathers side.

Great video with a great explanation of the percentages of DNA going back through the generations and that the percentages displayed on Ancestry are averages, which I think is overlooked massively nearly everywhere else, however there is one thing missing (maybe you covered it in the first video, I don't remember) which is that you are relying on the actual ethnicity readings being accurate. Ancestry says that one of my grandpa's parents is almost completely of Scottish ethnicity (he himself is from Ulster so it is possible, I'd say that he some Scottish DNA in him). Having extensively researched his family tree back on most sides to at least 3 generations, 5 or 6 on others and found no Scottish ancestors whatsoever. He has many DNA matches from that side that we think is the Scottish side (it is Church of Ireland and Presbyterian so more likely) that are cousins that went to Scotland, which I suspect skews the estimate from the data that Ancestry feeds into its algorithm. This may just be something overlooked by Ancestry during testing before it rolled out updates, but I would be very careful using ethnicity estimates for anything. I don't think there is enough base data from people who Ancestry knows is from a certain ethnic group in certain locations back in time to use it for anything other than a rough estimate (that may look spot on for some, might have oddities for others) of where your ancestors came from and definitely not to try and pinpoint certain people. Luckily I don't really care about the Ethnicity Estimate, we got my grandpa tested for the DNA matches to build our tree and break down some brick walls. The Ethnicity Estimate is just a gimmick, a sales tool so they can still more kits and maybe get people interested in subscribing off the back of it. If you already have an extensive tree you might be able to say that this part of the ethnicity comes from this part of the tree, but trace results I'd be very skeptical of, as well as and small countries that will have intermixed with neighbouring ones over the centuries, as DNA does not respect borders so small percentages may just be misreads.

I must really like you guys (I do!). I get a lot out of the videos here. They are very helpful. I just sat through three 4+ minute ads and two that totaled about 5 minutes in addition to those for a 12:52 minute video. The CRI ad was grating, just based on that ad alone, I'd never purchase their product. Your video, in conjunction with a conversation with my little sister yesterday, has given me a great deal to think about. In that conversation, she told me that both of our great-grandmothers were darker than typical "white" people. With one, there is a hint of why, but nobody wants to hear it. With the other, there is nothing but cricket noises. Thanks for all you do, Devon and Andy! Have a blessed evening.

This has been very helpful,my results are mainly african,from all areas.Surprised were Eastern Europe,Sardinia,India,Chinese.i knew about N W and South Europe.

This will be interesting. My daughter in law shows 1% southern Japanese for one parent and 6% for the other. A 3rd cousin that we believe in on the fathers side shows 2% Southern Japanese. It seems to agree with what we think, but it is iffy. The only person that we think is from the south may be the maternal grandmother, only because she is haplogroup C1a which is centered on southern end of Honshu island. Of course this is all subject to being totally wrong at any moment.

The graphic at 2:29 is amazing. Is it available for download somewhere? My screen shot is not very clear.

I am 3% Welsh and I found my Welsh ancestor to be my fourth great grandmother Mary Meredith. And I found another Welsh ancestor that is a fifth great grandparent.

I'm one of the lucky few who has written records (my mom's side...both her dads and her mom's side kept records that date back to 1700s. (Ironically, electric cars came before gas powered. A grandmother from the 1800s wrote about her life and such) German (her dad) and mostly Irish and some English (her mom). My dad's dad (my grandfather) side is a bit more complicated. We can't find anything further back than My 4th great grandfather. Even my grandfather and his siblings talked about how when they were kids that when they asked about their grandparent (at a certain point) were told to shut up and mind their own business. No one knows why. (I'm hoping Ancestry DNA Traits will help me find further back on this side of the family. On his mom's side, a cousin has traced back, allegedly to Chief Cornstalk and Pocahontas. My grandmother, dad's mom side, is primarily Irish. The hitch here is finding her mom's parents bc I keep finding 3 different last names for her...and they all link to marrying my great grandfather. I'm hoping that somehow the DNA test will unlock someone. Sorry for the ramble.

At least Ancestry shows which chromosome (and maternal/paternal) those low ethnicity percentages are on. I wonder if seeing which DNA matches you match on those chromosomes might give a clue about which side(s) of the family tree that ethnicity is. At least I think it works for some of my Welsh enthnicity on one particular chromosome, which probably ties up with that biggest group of matches I have. Not sure how I relate to any of them but think they are on one particular grandparent's side. Of those hundreds of matches a few have Welsh surnames and a lot of those with trees have Welsh place names/surnames in their trees. It seems like there is just one line (one ancestor or couple) a long way back that had that chunk of DNA that has survived down the ages through many generations and become more of a population group than a family. On the other hand I may have ancestors on several lines that had that same DNA at that point. The only known Welsh ancestor traced back to be born in Wales (so far) was a 5th great grandparent, so that line accounts for some Welsh DNA if I inherited any from him. Several other lines have Welsh surnames going back but not yet traced back to places in Wales. I expect the 4% could come from a few lines adding up perhaps all between 5th-10th great grandparents. No idea how I'm 3% German?! or 4% Scottish, or between 12-18% Scandinavian. (Ancestry says 12% and MyHeritage says 18% so perhaps it's really in between, or MyHeritage just have a lot more Scandinavian people on their database or a different way of estimating it!) Maybe very few people were purely one ethnicity until you go back 1000 years or more.

This may explain my Iberian ethnicity

I'm Mongolian and my ancesters were nomadic until about 1900. They settled in southern Russia, just east of Ukraine, around 1780. My DNA test results included Northern African and Southern Indian ancestry, each 3%. Not sure where that came from.

If my great grandfather was 75 percent Indian, what is the most likely estimate for the amount of Indian DNA me and three siblings will have?

My 3rd great-grandparents were 1st cousins once removed. His father and her grandfather were brothers; his mother and her grandmother were sisters. My 2nd great-grandparents were 4th and 5th cousins. Messes up the calculations. ☹️

On both MyHeritage and 23andme I have Nordic (and Baltic) but additionally on MyHeritage 1.4 % Ashkenazi and on 23and me 0.2% Italian. I understand that each of them can be a "reading error" because the letters on the 2 chromosomes in a pair can be falsely interpreted as belonging to one chromosome. However, my question is if there is any bearing that both companies find small amounts of related ethnicities?

Where can I get a fan chart like this one? Thank you

It seems I got a drop of ancient Ashkenazi Jews on my DNA. Well it did show up! I checked out my 4th cousins and notice that many have a sufficient about of Ashkenazi Jewish DNA. It appears that I am sharing a 3rd great grand parent with these relatives and I noticed they have roots in Germany, Poland, Spain, Italy, Czech and more, but I was born in NYC.

I have a cousin who I have determined his grandfather was the result of a NPE with his grandmother. He shows that he has 22% plus / minus Ashkenazi Jewish, which I have determined had to come from his NPE unknown grandfather. Excluding descendants of this NPE unknown grandfather and the known grandmother, Ashkenazi Jewish ethnicity matches start at 2% in 166CM (8 segments), 1.2%(85.5cm) in 7 segments, 1.1% (79.5%), and hundreds of other ashkenazi Jewish DNA matches in numbers below that. With endogamy, specifically Askhenazi endogamy, how distant could these matches actually be? 166cm via the shared CM tool on DNA painter gives a 52% of being perhaps a 1/2 2nd cousin, 13% of 3C - fairly close matches supposedly. But with an ancestor who came from an endogamous group, such as ashkenazi Jewish, is the relationships skewed much farther back or are these relationships indications fairly accurate? Are the CM ranges in the DNA painter tool still accurate but the probabilities skewed to farther out more distant relationships? Trying to determine if it's worth the effort to focus on these 1 to 2% shared DNA folks and assume they are fairly close relatives, in a search for an NPE grandparent.

Im guessing the approximate years could go up or down for 8 generations? Cause lets say for 6 generations the women had their 1st kid at 16 to 19 (in highscool or shortly after), that could drop the years closer to 150 for 8 genvs if a line of guys didn't start having kids till closer to 30 to 35, that could put the years up closer to 250 for 8 gen

and the numbers between the range? are on the upper or the lower?

I'm 3% West African.

I've mentioned before I learned I was Ashkenazi Jewish from an ethnicity. test I was luckily able to find this 4xggf. He doesn't account for all my AJ, but does account for maybe 75%. I have bits and pieces that are 5th+ggp , but I'm not going to "go down that rabbit hole." They seem to be from the Netherlands or western Germany. I did a big Y test on my mom's nephew and maybe 20% of his big y SNP matches are autosomal matches with my mom. They are all from Ukraine, Belarus and Poland. On my heritage 10k of my mom's 20k matches have AJ. On 23andme where they publish self-reported ancestral names, the whole list is AJ names! My mom is maybe 15%AJ with no recorded legitimate AJ before the middle of the 18th century so how is any of this possible? If I can make a suggestion you should do a video just on AJ.

Hey doctor, based on myheritage result, I am 14.6% Japanese and Korean, how far could this traced back? I’ve seen my great grandparents, neither of them are Japanese

Isn't the first complication a single ancestor vs an ancestor couple with the same ethnicity.

I have this for my African and Tupi Guarani ancestry. I can’t see records for them until they were baptized.

I'm 61 per cent Iberian, but I can't find any foreign relations for at least as I'm aware of 3 generation s, I'm English so I'm baffled.

I’m 35 percent German which is from my dad side he’s dead do you have any idea what percent German he could have been

Oh wow Me to it was always a f in secret im mad at this stuff

How far back is 17,9 % Ethnicity ?

My great grandmother half sister dose show 3% native American. So if her 3x great grandparent was native American that would probably be my 6x great grandparent. I also have 1% native American.

Whatever gimmicks it takes to get my DNA cousins to test! 😘

0.0 I´m kinda "concerned"(not really but still) I mentioned in the other video the roughly 30 % of skandianvian DNA on my fathers DNA and yeah its all still true to them living next to the skandinavian border I actually asumed that the mix might happend more far back but constantly but we do have at least the data of all 3rd grandparents (and a lot of lines back much further and none...i mean NO ONE of them is actually plausible from above that border. No a single. Just one Person has intermarried there- but this is no direct ancestor. I got some cuckoo vibes....XD.

Where is my 1% Nigerian from? Nobody knows. Not even my family tree.

I think you don’t understand, when inheriting half dna from your parents doesn’t mean inheriting half of each ethnicity

My Ethnicity England & Northwestern Europe 32% Germanic Europe 27% Scotland 18% Swedish & Denmark 17% Norway 6%

My sister born in 85 gave birth in 2013 Our mom was born in 53 Grandmother 1919 great1898 ----- Our mom's father 1900 his father 1840 Great he and his wives immigrated from Norway. Our father was 38 when my sister was born His parents and grandparents ages I don't know. I know my mother's father knew My father's mother when she was grade school age. (I WON"T be able to use that for my family).
