Returning to Blogging in the New Year – Refreshed and Excited

The definition of taking a break is interrupting one’s activity briefly. When I went into hiatus the end of October I didn’t expect it to be over two months before I would come back to blogging.

I was touched by the people who reached out to me while I was missing in action. Several messaged me directly to find out if all was well. From my young 3C1R Luella who I’ve known nearly two decades to my #1 reader/commenter/blogger Amy to my follower from Brazil whose ancestors lived in the same village as my ancestors.

All were worried. They didn’t know I’d fallen into a rabbit hole, spinning down winding double helix strands carrying our DNA. It took me a while to gain my orientation and find the even more twisted ladder out of the hole.

Who’s Fault Was It?

 

Blaine T. Bettinger shared my post How DNA Results Helped Discover Luxembourg Emigrants in the Facebook group Genetic Genealogy Tips & Techniques.

Great blog post about how the DNA Match Labeling extension for Chrome helped solve a genealogical mystery! Genetic networks and clustering tools are the future of DNA evidence!

I had no idea I was even on Blaine’s radar and it explained a spike in traffic on my blog during the week following the post. Being noticed by Blaine was fantastic.

Even more incredible was the help I received from a member of the Genetic Genealogy Tips & Techniques group.  Jonathan Brecher sent a message offering to run a Shared Clustering tool he has developed on the AncestryDNA test I manage to help me tickle out the maternal matches.

Shared Clustering

As mentioned in the above post [over two months ago] maternal matches are few and far between as that side of my family tree is Luxembourgish with a few branches which reach into France and Germany during the periods of time when the area belonged to Luxembourg.

Jonathan’s tool is not yet available to the public. He sent a CSV file with the heat map of my matches and a list of the clusters in text format. He paid special attention to my starred matches as these were the ones I had already been able to identify as maternal.

The heat map generated 66 clusters. Four of these are for maternal matches while 61 are for paternal. One cluster remains unknown at this time but looks more paternal than maternal.

The number of matches in each cluster varies greatly. There are a dozen clusters with only 2-10 matches, 33 between 11-100, 11 between 101-200, 4 between 201-400, 5 between 401-500, and one with 705!

I pinned down the fourth maternal cluster this past week – when I was supposed to be working on this post. I felt the pull of that rabbit hole, again, and checked each match and their trees until I found the connection. They descend from immigrants, two BAUSTERT brothers who were great-grandsons of my 5th great-grandparents Matthias SCHRAMEN and Anna Barbara LEIBRICH (BURG) of Ferschweiler, Eifelkreis Bitburg-Prüm, Rheinland-Pfalz, Germany. Did the Baustert brothers know their 1C1R Nicholas SCHRAMEN had emigrated about 20 years earlier and originally settled in Iowa where they were also found?

What I’ve Been Working On

As the CSV file Jonathan sent included my notes, the paternal clusters were easily identified as coming from one of the four paternal grandparents’ branches. Some could even be associated with specific branches of a grandparent’s ancestral line.

I’ve been amending my notes on AncestryDNA to reflect the cluster number as well as a surname and possible generation. The cluster numbers are only for reference and make it easier to sort them on the AncestryDNA page using the Chrome extension AncestryDNA Helper or in Genome Mate Pro when sorting the MRCA (most recent common ancestors) notes.

Cluster 40 with 13 matches is labeled GROELINGER-MERGEN(6) as the MRCA have been identified as my 4th great-grandparents (6 generations back) Johann GROELINGER and Anna Maria Benedikta MERGEN. Six of the 13 matches have been identified as descendants of this couple. I’ve sent messages and am waiting for replies.

Once the notes have been fixed on AncestryDNA, I move all matches for a cluster over to Genome Mate Pro (GMP) using another Chrome extension, Pedigree Thief (collects the match information, notes, and the shared matches). When the matches are in GMP, I begin adding the matches’ trees once again with the Pedigree Thief which reads the pedigree view of the tree and converts it to an Ahnentafel chart. GMP has a very steep learning curve and I’m still trying to assimilate and grasp the abilities of the program.

I’ve developed a routine and am slowly getting matches which have been associated with a cluster entered into GMP. Nearly half of the clusters, the smallest, have been added. The larger clusters remain to be done and I’ll be spacing them out a bit. And of course, as new matches are found on Gedmatch Genesis, FTDNA, and MyHeritage they are also added to Genome Mate Pro.

I still feel the pull of the rabbit hole but I won’t let it get in the way of my returning to a regular blogging schedule.

Dear Cousin – We Have a DNA Match, Now What?

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.

Running the gamut of emotions…

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.

Dear Cousin,

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 Genesis.

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.

UPDATE from GEDmatch’s homepage: As of 12/18/2018 all new raw DNA kit uploads are only accepted by Genesis. The legacy GEDmatch site will continue to be available for some time, but results are “frozen” with all new kits being accepted, processed and results available only on Genesis.

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 Genesis and FREE.

Would you please consider transferring your raw DNA to GEDmatch Genesis? Here are the latest instructions: [If you already have your GEDmatch Genesis kit number,  scroll down to Thank you to continue reading.]

Register with GEDmatch

To use GEDmatch Genesis you need to register for the site. The link is https://genesis.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.

AncestryDNA screenshot

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.

AncestryDNA screenshot

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.

AncestryDNA screenshot

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 Genesis. Click on Generic Uploads (23andme, FTDNA, AncestryDNA, most others) on the right side under Upload your DNA files – for Genesis BETA ONLY. 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.)

Meanwhile…

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:  (see the kit number in my message to you). 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 3000 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 complete all processing and have good status (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.

Screenshot courtesy of GEDmatch

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.

UPDATE (5 January 2019): The option to upload a GEDCOM to Genesis is now available. The above directions are for the classic GEDmatch site. Please go to the homepage of Genesis, scroll down to Upload GEDCOM (Genealogy .ged files) on the right side and follow directions.

You’ve uploaded the raw DNA and your GEDCOM file (optional, but so very valuable to your matches) to GEDmatch Genesis. 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 3000 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. Presently (5 January 2019) not available on the new Genesis version of the site.

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 Genesis but the most useful in the beginning. When you are just starting out, DNA is a complicated subject. 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!

Thank you, cousin, for taking the time to read this. If you already have your AncestryDNA on GEDmatch Genesis please send me your kit number. Usernames on Ancestry do not always match up with the name or alias used on GEDmatch Genesis.

If you decide to upload your raw DNA to GEDmatch Genesis, 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:

How I Use and Manage AncestryDNA Notes.

UPDATE (31/12/2018): Please note this post has been updated to reflect the switch over from GEDmatch to GEDmatch Genesis.
