GEDmatch Tag Groups plus new One to Many

Being able to group my cousins from different lines into colored “tag groups” on the GEDmatch site is a wonderful new feature. It makes it easy to quickly see which line a new cousin fits into because the new Tier 1 one-to-many display uses those colors to highlight the kits belonging to a group. See the image below for a colorful example of my own one-to-many.

Tag Groups

Tag groups are for everyone, not just tier one members,. They can also be used to select what to look at in the “Multiple kit Analysis” function. However they are not yet included in any of the other functions, like the people who match both kits, triangulation or matching segments and of course not the regular one-to-many.

UPDATE 26 Jan 2021: Both Beta One-to-Many Tools include tag groups but you have to check the box for them, either one or all.

Here is a quick example of how a new close cousin can be visually assigned to a line when you use the tier 1 one-to-many on their kit. My tag groups use yellow for close family, aqua for paternal first cousins, shades of blue for my Etne lines, green for my Munson line, and purple for my Wold line. Which line is this cousin on?

Right, she is a Munson.

Other New Features

I love that the newest pages at the GEDmatch site include a top menu. and use tabs to make for a more compact display

Also the new Tier 1 version of the one-to-many is outstanding. In addition to showing those colored tag groups. it has search boxes at the top of every column for just that column. The form to invoke the one-to-many is gone, instead the selection is neatly across the top so you can change it dynamically. The long details that used to be at the top of the page now only show up as a pop-up window if you click the tip button.

Yesterday I did a presentation on all of this, click here for the slides which show many of the details of these new features.

Following an X match in the Etne farm books

etnesogabooks

Having just received the Etne, Norway local history books (bygdebuker) for Christmas, I have spent countless hours looking at my ancestors in them. Naturally I have been trying to think of even more ways to use these books.

An idea that came to me was to look at my Dad’s one-to-many X matches at GEDmatch.com and see if I could find a match where I could follow the lines and connect them to Dad’s maternal grandad via those books

The largest X match he had with an unfamiliar name and email was to *k for 26.8 centimorgans (cMs) and it included a small autosomal match of 6.3 cMs. This seemed promising so I used the user lookup function on my GEDmatch home page and was delighted to see that she had uploaded a GEDCOM.

The GEDCOM number is clickable from the lookup result and it takes you to a page listing the individual. Of course what you really want is the pedigree to quickly scan for relatives in common and there is a button for that at the top of the page. Better is to use the compare 2 GEDCOMs feature from the home page to compare your match’s GEDCOM to your own. Works great if you both have deep trees but I had no luck with that for *k.

Next I clicked on the pedigree button at the top of her individual listing in the GEDCOM which took me to her pedigree page. Nothing jumped out at me and most of them were from Germany.

Taking it to the Next Level – DNA Spreadsheets

Perhaps this post needs the subtitle , “My Perfect Cousin Goes to GEDmatch.”

Most of us can keep track of information in spreadsheets. So how to do that with DNA? Well, the idea is to keep a list of matching DNA segments so that a new match can be compared to your known family members. That way you may be able to see where they fit in.

If you have tested at 23andme, MyHeritage. or Family Tree DNA, you can download your list of matches with their matching DNA segments either directly from your testing company or by using the tools at DNAgedcom. However AncestryDNA does not provide a list of matching segments.

Why would you want those? The short answer is to figure out which line a new DNA cousin belongs to. For the long answer, read on. For more posts about DNA spreadsheets click here or in the tag cloud, lower right hand column.

tier1smll AncestryDNA testers can make a DNA segment spreadsheet by using any of a number of utilities at the GEDmatch web site. Start by uploading your raw DNA data (click here for that “how to” post). Your results will usually be ready for full comparisons the next day. Then buy the tier 1 utilities for at least one month ($10).

My preference for making a first spreadsheet is to use the Tier 1 GEDmatch Matching Segment Search. Then I go through the top matches from the ‘One-to-many’ matches report with that spreadsheet as a reference. I add notes on what I discover to my new spreadsheet.

Here is the step by step of what I did for my perfect cousin J.M. whose AncestryDNA results I blogged about in my previous post.

Using the GEDCOM capabilities at GEDmatch.com

UPDATE 4-JUL-2020: In the column labeled “GED Wikitree” on a Tier 1 one to many report, if the word “GED” appears in the row of a match, you can click on it to get to that user’s gedcom. Otherwise you can find if a match has a GEDCOM by using the User Lookup function. How to navigate that GEDCOM is covered on the second page of this article.


Take the kit number of interest and plug it into the user lookup form. On the next page, with the information about that kit, it will either say NO GEDCOM UPLOADED or there will be a GEDCOM id number. That id number is now clickable and will take you to the person associated with this kit number in the GEDCOM.

GEDmatchUserFrodeIf you have not uploaded a GEDCOM to GEDmatch.com then I highly recommend that you do so. It is helpful to be able to compare your GEDCOM to that of a DNA match. I prefer just 10-12 generations of my ancestors (privatized) as my full family file is way too large. My theory being that is enough generations for DNA matching and I only want ancestors for my DNA matches to look through.

I have used red arrows on the image to the right, which is an excerpt from the current right hand column of GEDmatch home page [as of 4-jul-2020] to show where to upload your GEDCOM file and where to click to do a user lookup.

Here is a the step by step example:

New Utilities at GEDmatch: Tier 1 for paid members

There are four exciting new utilities at GEDmatch.com which I plan to cover in depth over the next several days. These are only available to for people who have donated  at least $10 (every additional $10 gets you these for another month). A good way for GEDmatch to pay for their extra server costs. The rest of the site will remain free. The utilities are:
Tier1

  1. A Matching Segment Search – Get a list of all your segment matches suitable for cutting and pasting into a spreadsheet
  2. A Relationship Tree projection – calculates probable relationship paths based on Autosomal and X-DNA Genetic Distances. It is experimental, try it and give them feedback
  3. Lazarus – Construct a kit to represent a close ancestor, wow!
  4. Triangulation – takes your top 300 matches and finds which ones match each other with details. The format can be copied to a spreadsheet
