Making the first contact with a DNA match has us running the gamut of emotions from excitement at finding the match to the disappointment of there being no tree. From the joy of hearing back to the exasperation of never receiving a reply. From the frustrations of the trying to explain your need to use a chromosome browser to evaluate the match to the delight of making contact with cousins who are ready to work with you.
I have tried different approaches in writing messages to DNA matches on Ancestry. Keeping them short, giving more or less information, asking right out to upload to GEDmatch, sending my email in the subject line, including links to articles on my blog about shared ancestors, etc. The number of persons who reply is very low. The list of reasons for this is too long to go into.
So I’ve decided to use my blog to write to my cousins. I will continue to write short messages and include a link to this post. The instructions are up to date – I tried them out while writing. If anything changes, I can fix them and won’t have to copy/paste and re-write instructions I have been sending in messages or emails.
We have a DNA match, now what? Thank you so much for taking the time to read this and getting back to me. AncestryDNA does not offer a chromosome browser. I find the best solution to be GEDmatch.
GEDmatch provides DNA and genealogical analysis tools for amateur and professional researchers and genealogists. Most tools are free, but we do provide some premium tools for users who wish to help support us with contributions. You will need to upload DNA and / or genealogical (GEDCOM) data to make use of the tools here. Registration requires your name, email and a password of your choice.
Did you notice in the quote that MOST TOOLS ARE FREE? Yes, there are some premium tools which require payment but the chromosome browsers we are lacking on AncestryDNA are on GEDmatch and FREE.
Would you please consider transferring your raw DNA to GEDmatch? Here are the latest instructions: [If you already have your GEDmatch kit number, scroll down to Thank you to continue reading.]
Register with GEDmatch
To use GEDmatch you need to register for the site. The link is https://www.gedmatch.com/login1.php
Fill out the form per instructions and click on Register.
Download raw DNA file
The next step would be to download your raw DNA from Ancestry. If you haven’t done this before:
On your AncestryDNA page in the upper right hand corner click on Settings. On the right is a Download RAW DNA Data button.
You will be prompted to enter your Ancestry password and check the box showing you understand Ancestry is not responsible for the file they are sending you. Click Confirm.
As soon as you click Confirm a window will open advising you that they are sending an email to proceed with the download. It may take up to 5 minutes for the email to come in.
The email has a Confirm Data Download button. Be sure to make a note of where you save the file on your computer. The request expires after 7 days or after the first use.
Upload raw DNA file
Login to GEDmatch. Click on Generic Upload FAST on the right side under File Uploads. Fill out the form and upload the file without unzipping it.
(If you are a Mac user the file may have been unzipped during download. As a Mac user, you are likely aware of this and know the procedure to get it zipped. The zipped file may be in the Trash.)
It doesn’t take long to upload the file but the processing on site may take a day or two. This means you will NOT be able to use all features right away. A one-to-one compare will work before processing is finished. To try this one out, compare your kit to one I manage: A131214. Please email your number to me as I won’t see you’ve been added until it’s completely processed. If our match is lower than my top 2000 matches it will not show on my list but I can still do comparisons with your number.
What else can you do?
While you are waiting for your kit to tokenize (GEDmatch lingo) consider exporting a GEDCOM from your genealogy software and uploading it to GEDmatch. Using genealogy software allows you to export as many or as few individuals in your tree as you need.
If you have a tree on Ancestry you can export your family tree data, as a GEDCOM file, to your computer via Trees > Create & Manage Trees > Manage Tree > right side > Export Tree.
When you click on either of the versions to upload a GEDCOM file to GEDmatch you will find some suggestions pertaining to the file. The most important thing to remember is that the GEDCOM will be public and viewable to all persons who have access to the GEDmatch site. For this reason, it is recommended that you privatize living individuals prior to uploading.
You’ve uploaded the raw DNA and your GEDCOM file (optional, but so very valuable to your matches) to GEDmatch. On the homepage, there are some things which will be useful to you.
User Lookup : This lets you check by kit number, GEDCOM number, or email address to get more information on a person using GEDmatch.
GEDCOM + DNA Matches : This will generate a list of all persons who match you (or whoever’s kit # you search) and who have a GEDCOM file attached to their kit. This is practical as you won’t have to use the User Lookup to check each kit to see if they have a GEDCOM file. Closest DNA matches are at the top of the list.
One-to-many matches : as soon as your kit is processed you will be able to check all matches to your kit. It will generate a list limited to the first 2000 matches with the closest matches at the top. When you do this the table will have some boxes in the first column (kit #) highlighted in different shades of green. The darkest are new matches. As time goes by the color gets lighter and finally turns white. In the column GED/WikiTree you will find links to a match’s GEDCOM file or WikiTree. The Select column allows you to choose 3 or more kits for further comparison. Click on the Submit button at the top in the text area for additional display and processing options.
People who match one or both of 2 kits : When you check your kit and another kit with this tool it will give a list of all matches shared by both at the top, followed by a list of all kits who match the first and not the second, followed by a list of all kits who match the second and not the first. I check all the boxes (of the people who share), submit, and then use 2-D Chromosome Browser to view the matching segments on the chromosomes. This helps to narrow down the matches both kits have to others on the same chromosome segment. As chromosomes are two-sided further analysis is needed to determine if the matches are paternal or maternal.
This is not a complete list of what you can do on GEDmatch but the most useful in the beginning. DNA is a complicated subject when you are new to it. Take it slowly and one day, after you have read something for the 3rd, 5th, 10th time it will sink in and seem EASY.
Thank you, cousin, for taking the time to read this. If you already have your AncestryDNA on GEDmatch please send me your kit number. Usernames on Ancestry do not always match up with the name or alias used on GEDmatch.
If you decide to upload your raw DNA to GEDmatch, I will do a one-to-one compare between our two kits as soon as I know your kit number. Then I’ll add the chromosome information to Genome Mate Pro (GMP), the program I use to keep track of all matches and to map chromosomes. I can then assign the segment(s) we share to the Most Recent Common Ancestor(s) (MRCA) and Voilà!
I will have our shared segment(s) in living color on my chromosome map and can use them to assist with other matches on the same segment. In turn, if we don’t know who our MRCA is, the other matches on the same segment will aid in the analysis.
There are also other possibilities: FTDNA and MyHeritage will accept uploads of raw DNA from AncestryDNA and they both have chromosome browsers. It would be very much appreciated if you choose to upload your raw DNA to any of these sites. But if you don’t feel comfortable doing this I will understand and we can continue working together, using the tools available on AncestryDNA (Shared Matches, Circles, Map and Locations, Pedigree and Surnames).
If you have any questions feel free to get in touch with me and I will do my best to help. While we are on the subject, the following articles may be worthwhile to you for managing your DNA results on AncestryDNA:
