I’m right there with you. The video is outdated too, the site doesn’t look like this anymore. I have joined groups on facebook but everybody talks over my head. There is nobody willing to help!!!!

[@asgio27]

@@az55544 I understand, and this is difficult for me too, but I think he just tries to cover the very basics, without delving into the explanation of each column too much, as that would confuse people like me even more. There is a plethora of tutorials out there, from this teacher and more, and I am very flustered, but this tool demands time and focus, and so far, it is my fault that I have not devoted either to the extent it requires, and I think that applies to many. I love science, but, this is a complex tool , and I don't think it will be mastered without due diligence. I think he did a good job for his intents, but, with every video I've watched, I leave confused and knowing I have a long way to go.

Thank you for making this clearer..

Is there a way to tell if the DNA is connect to my mothers or fathers side?

[@eugrus]

not by the autosomal DNA alone

[@richardlanham4415]

If you can get someone (living) that you believe is on one side of the family, such as a close cousin/aunt/uncle, to give a sample, then you can use your kit and theirs to identify the side of the unknown kit.

[@FamilyHistoryFanatics]

You need to compare your DNA to known matches on your mothers and your father's side. Wherever the matches triangulate, you could determine which side of the family additional unknown matches are related. kzbin.info/www/bejne/mZa8eKlsh7OZeqc

[@FamilyHistoryFanatics]

Evgeny is partially incorrect. You can use only autosomal DNA in connection with other known matches to determine paternal/maternal lines.

[@FamilyHistoryFanatics]

The new Genesis makes it much easier to sort out matches that are closely related. Also, tag groups can help to make matches easier to see.

[@kevinlassiter9285]

Good evening! I have one quick question. Person A finds a match (person B) on their "one to many section" of Gedmatch. They both share cousins, easily found on the "one-to-many section", with DNA segments seen on the "one-to-one" section. However, when Person A does the "one-to-one" test on Person B, to explore shared DNA on particular chromosomes, Person A sees no shared DNA with person B. Are Person A and B distantly related? They see each other on the one-to-many section but see no shared DNA on the "one-to-one" section.

[@FamilyHistoryFanatics]

One-to-Many uses a quick algorithm and is less accurate than One-to-One. Any match should always be confirmed through One to One.

I'd like to know what the pink highlights are in the overlap column, mean. I seem to have quite a few.

[@borreliaetc]

The one to many page explains it up top. "Matches with low overlap have that field highlighted with a pink or red background, depending on the overlap value." (Overlap is the number of positions that exist in between you and that highlighted kit) Red is basically saying be weary, low overlap. It will be hard to figure out how you match

[@cliffsheets73]

I was about to ask the same question, because the explanation at the top isn't really clear. Can you make a video on what to do with that information?

[@ctchickenmom]

@@borreliaetc it does say it at the top, but its not a good answer. I have many with a low overlap. Why are they not all pink? What constitutes 'low'? Why are some lows pink and not others? There are no parameters.

[@borreliaetc]

@@ctchickenmom overlap seems to be generally new. (I don't check into gedmatch every day or even month, so not sure how new.) This is just a guess; I think when the comparison kit has been uploaded might have something to do with whether or not you show any amount of overlap. For example, I have my mother and brother's dna, and it says N/A overlap. Lol but I added them in years ago. One of my 1st cousins that put in her dna not that long ago shows overlap. One of my known 5th cousins 2x removed put her dna in and we checked, we didn't match. But she's so many positions away from me. We met by having common ancestors on both of our Ancestry Trees, before either of us did dna testing. A video with clarification would be wonderful, all I have are guesses. I hope everyone is well.

Overlap is just the number of SNPs that could be compared (not the number that matches). Gen 5 means they are distant matches. To learn more about overlap, check out this video What is DNA Overlap on GEDmatch? - ://kzbin.info/www/bejne/rYHXpIuVfrJ5a80

GEDmatch is not as user friendly as I would like, which is why I've tried to simplify the complex. However, even my wife thinks GEDmatch is too difficult to use. I would recommend leaving your DNA on GEDmatch to allow other users to connect with you. It can't hurt.

[@FamilyHistoryFanatics]

While you can set the filter lower, I would set it at 7 cM. Below that point, you start having false matches. kzbin.info/www/bejne/hXeYXoOGgrapeck

[@Balkanophile7897]

​@@FamilyHistoryFanaticsAbove 7cM I get extremely many false matches too, how come I and my Kurdish relative share the same English (Anglophone American) or Serbian cousin? Among different DNA companies I found the matching service of MyHeritage the most accurate, because the European/White relatives are all average or low reliability unlike GedMatch or LivingDNA, there also appears Anglophone cousins on my match as a 3rd to 5th cousin. White Americans can't be more related to me when my ancestry is Balkan instead of Western European, so I think GedMatch, LivingDNA and 23andMe has a lot to improve when it comes to DNA matching. I have no comment on the ethnicity estimate of these companies, as for me they are fairly accurate so there is nothing to say to that. Another person from Southwestern Turkey gets 0% European after two updates on 23andme and the majority of his matches are again people with English sounding names from the USA. How is that mix between a Turk and a Westerner possible when they share little of common history? Also I have no comment on your expertise in geneology so don't take my criticism personally but after some research I've found many inconsistencies in this matching function of Gedmatch. I am fairly disappointed.

Your DNA kit compares to all other kits each time you run the one-to-many tool. If you're not finding matches there are a couple of possibilities. 1. Your DNA matches have not transferred their DNA to GEDmatch. 2. Your genetic relatives not taken any test. 3. You're struggling with the case of small families. I talk about that here. kzbin.info/www/bejne/pnunm3udZpiEnas

Pretty much all of my matches are red. But my top match has almost 300 cM in common even though the overlap was around 50k. Does this mean that I could be more related? Or does it negate the match?

The low overlap may mean that the actual shared cM is slightly lower (maybe by 10%), but overall, I would say this is a pretty solid match in the 2nd cousin range.

Great tool. So glad GEDMatch puts your links on their pages. This video mentions that I "should" find my matches on the various genealogy websites, but... I did Ancestry and they did Ancestry (according to the GEDMatching tool), and according to the GEDMatch, we should be somewhere in the 3rd cousin range, but when I go into Ancestry and "look" them up, I see them, but Ancestry says we have no DNA matches. I'm confused. Is there another resource tool/video that might help me figure out what this "means?"

[@FamilyHistoryFanatics]

On Ancestry's end, they may not meet the threshold for calling you a match. Each company has their own algorithms to determine matchiness.

[@rowanmayhew]

have you done a video on the TAG tool?

[@FamilyHistoryFanatics]

[@aandmband1955]

What do you mean by "top" matches? If I select a limit of 100 matches, is it a random list of matches, or are the matches sorted and than displayed?

[@stephenfeingold6395]

Thanks for the great video. One question. You did not explain what "Migration F2" means in the last column. So what does that mean?

[@zanzaboonda]

I'm not positive, but I think that indicated it was migrated from the old platform to the new Genesis platform. There are single-letter codes he mentions next to them. E.g., A for Ancestry, T for FamilyTreeDNA, etc. I think he mentioned most of those, but I forget. But I think it basically means "pre-Genesis"?

[@FamilyHistoryFanatics]

The last column is for the company that the test originally occurred at. Several years ago, GEDmatch denoted this by the first letter of your kit number. When they changed the numbering system the default for this new column was "Migration F2". Individual users can go in and change that to the correct company, but not everyone does.

[@claudiacampbell848]

Hiya, I am trying to understand the Beta one to many tool. Can you explain if the x chromosome is the mother DNA only should up in the matches? Many thanks

[@Raleighrell]

Good information. But question, I am searching for my biological father and on gedmatch out of 3000 matches found the closest generation is 4.1, realistically what are my chances of finding someone closely related from those results?

[@FamilyHistoryFanatics]

From those, probably not good. But more people are testing every day so the matches you need may show up in the coming years.

[@gdaymates431]

I'm in the exact same situation and it feels pretty useless. Doubt ill ever find out who he is. Just have to accept it really.

[@Seashellsbytheseashore21]

get an ancestry and 23andme kit.

[@theresa4960]

How can you triangulate with a match's matches so that you can identify maternal or paternal origin of your matches?

[@BeatlesFanSonia]

Is it better to be opt in or opt out of the police part of this site?

[@FamilyHistoryFanatics]

There is no extra benefit/privileges you get on the site by opting-in. If you have no qualms with police using the database to develop potential suspects, then opt in.

I’m trying to find my birth parents, I did a dna test and the closet matches I have are 2nd cousins. I’m not sure what to do

[@mikeanderson2404]

HELP. do you have a video that explains ethnicity? I have looked high and low. Ancestry says I am 86% Irish and 14% Nw Eu. My Brother is 46% Irish and 30% Russian and 15% Baltic (Ancestry test). So I loaded into Gedcom and I see a Pie Chart with like North Atlantic 50% etc etc and I cannot relate that data to Ancestry. It becomes obvious if true that there are two fathers involved but I want to get the % make up via Genesis to validate this and create data that I can understand since the pie nomenclature does not say Ireland or Scotland or Russia or Poland etc. Can you tell me what I need to do? I see some non functional tools that I have tried to create a "map" but they dont see to work. I am stuck.......................TIA Hope this makes sense.

[@FamilyHistoryFanatics]

I'll be doing one on GEDmatch ethnicity results in the next few months.

[@clenhard]

it does not mean there are two fathers. What percentages of markers you get from each parent is not the same. For simplicity's sake, let's pretend your mom was 100% Irish and your dad 100% Russian. You might "be" 80% Irish, 20% Russian. Your brother from the same parents could be 99%Russian and 1% Irish. As more people meet and travel, populations become mixed and the percentages become wild. Additionally, "ethnicity" is a troubling subject. There is no one genetic code for each ethnicity, since borders have changed over time and populations have migrated, separated, returned, intermarried, etc. NW EU is not that far, distance wise from the Baltic region, which is also not far from Russia. In the end, you and your brother are really not that far off from one another.

[@kevinjames8529]

Are there any plans to add Y kits to GEDMATCH?

[@FamilyHistoryFanatics]

There's always a possibility but probably not. FTDNA has a great set of tools and there are few other tests that do genetic genealogy with YDNA. So there really isn't much need.

[@gh0stb0n3r]

Which column more closely corresponds to the cMs displayed on Ancestry matches? My Gedmatch lists includes 2 people I recognize by name from my Ancestry matches. One of them, "M", on Ancestry has 158 cM across 7 segments, and the total cM shared on GedMatch is 150 - okay, close enough, I suppose. But the second relative, "S", on Ancestry says 41 cM across 3 segments, but the Gedmatch colums give a largest segment match of 28 and a total match of 82 - neither are quite as close a number.

[@FamilyHistoryFanatics]

Each company counts matching segments differently. Some of them are close (like your one match) and others of them can be very different (like the other match).

[@kaikid3036]

I cannot link through on "ONE to MANY" . I get an error message: "Duplicate Kit" . What do I do now ? Thanks

[@jumama2032]

I had the same problem this may mean you already have a GEDmatch account and have a kit number. Go back to the main page and scroll down looking on the left hand side till you see user profile, there should be a box that says Legend in it if you read through that box it should tell you how many kits you've got, their kit numbers and if one is a duplicate and how to get rid of duplicates. Hope this helps.

[@haweygs]

Can you do a search on email address or user alias name in the Beta version? I noticed some boxes above the columns.

[@FamilyHistoryFanatics]

[@catarinaduarte225]

Hello! Im new on the site, and yesterday my kit was completed. On the generations colum I have a match of 3.6, whats the relation with this other kit?

[@FamilyHistoryFanatics]

Watch this video to better understand that column. kzbin.info/www/bejne/jGrLp3yEd9-No8U

[@marywhite2907]

I unfortunately paid for Tier 1 and now just want to do a one to one comparison and can not seem to do this anymore - Sometimes you just want to look at one match - not all the noise. I want to be able to choose whether Tier 1 comparison or just one on one comparison for easy upload into DNAPainter.

[@FamilyHistoryFanatics]

The basic tools should still work for you even if you have a Tier 1.

[@ViolaBruckmann]

Mein Englisch ist nicht so gut. Gibt es dieses Erklärvideo auch auf Deutsch?

[@noreenkruzich9511]

In regards to SNP and cM, if you know the match is quite a ways back in the tree, wouldn't lowering the required SNP and cM help in this case? Are you saying cM matches around 3.7 to 5.2 can be disregarded and are not matches?

[@FamilyHistoryFanatics]

The problem with lowering the SNP, is that the number of false matches increase. At around 15cM 99% of the segments are true matches. At 7cM, about 50% of the segments are true matches. At 3 cM 90%+ of the segments are false matches. So separating out true matches from false matches below 7cM becomes increasingly more difficult and time consuming.

[@anettemodee4146]

Thank you for this video. The one-to-many Beta is really valuable. I don't understand how the X dna match can be zero (0) when there is a match in the autosomal columns when there is a match between a female and a male person.

[@FamilyHistoryFanatics]

Because the X inheritance is unique and it is only one chromosome so much more likely to get lost in just a couple of generations.

[@dawntheberge5876]

What if you WANT to find very distant relatives to help find very distant ancestors? Should a low cM, say 2, be discounted?

[@FamilyHistoryFanatics]

Most likely (>90%) a 2cM match is a false match.

[@valeriep.4716]

Andy, I need your help. I've been using Gedmatch for a couple of years and it worked fine, suddenly, about July 3rd., I started getting incorrect chromosome readings on MKA' 3D, and the other tools. The One-To-Many tool works correctly as always, but when I submit my matches to the other tools, I get a different reading or it shows no shared DNA at all. When I go to the little GM link on WikiTree, it appears I'm no longer related to anyone! I've contacted GM and got the response from "Aaron" that he will look into it. Still, nothing is done. My Tier 1 has run out today, but I can't renew it until it is working again. Am I the only one having this problem?

[@FamilyHistoryFanatics]

This sounds like a technical issue that the team has to look into for you. Reach out to them again to get an update.
