Using GEDmatch tag groups

Apr2

The multiple kit analysis function works beautifully with tag groups. Another benefit of tag groups, is that when I don’t remember the kit number of a cousin whose results I wish to view, I can look it up quickly by displaying the people in that tag group (from the View/Change your profile (password, email, groups) on the top left)

My previous post about tag groups mentioned that tag groups are a quick way to see where a new match fits in by looking at their one to many page for your tag colors. However this is less useful for a distant cousin match (fewer colored tags) or an iffy paper trail match. In those cases I put the new person in my Unknown group (which only ever has the one person being analyzed) and then compare with all the relatives I expect a match to, by using their tag groups.

The main GEDmatch page has a box called Analyze Your Data and towards the bottom of that box you can see Multiple Kit Analysis with a big red NEW next to it. The “new” is because you can now use tag groups for this analysis. When you click Multiple Kit Analysis to get to that function, you will see a page like the one shown below. The old way of doing multiple kit analysis, by typing in each one, is still available from the Manual Kit Selection/Entry tab on this page or by checking boxes in various other functions like one-to-many.

My tag groups: note that I am using shades of aqua and blue for my Etne, Hordaland, Norway descended cousins

You can check the tag groups of interest and compare them to the new person (the Unknowns group for me) in all the wonderful ways the multiple kit analysis gives you (Click here for the slides on that from my most recent GEDmatch presentation).

Recently I have been searching for a “Lee Oleson” who is the grandfather of a third cousin match at Ancestry. He was only in town long enough to get my match’s grandmother with child. This third cousin’s one to many lights up with the colors of my Etne, Hordaland, Norway side relatives.  So I set myself a project of tracing forward all the descendants of the eight children of my Etne great-great-grandparents to see if I could find Lee.

Genetic Communities at Ancestry are live

Mar29

Ancestry.com‘s genetic communities are a good way to understand your family’s journey for the last few hundred years. Unlike the ancestry composition percentages, these communities are more recent and include a write up of the history of each group starting in 1700.

Many of my favorite bloggers posted about this yesterday. If you want to understand something about the science which combines the use of trees plus good sized matching segments, I recommend Leah Larkin’s analysis of Ancestry.com‘s white paper here – http://thednageek.com/the-science-behind-genetic-communities-at-ancestrydna/

Since I frequently work with adoptees, I am really hoping this helps with that analysis. I am finding that people with deep American roots have far more communities than those of us with recent immigrant ancestors. The adoptee I am currently working with has six communities! Shown above.

He knows his mother’s father and that is the Deep South community. I suspect that the New Jersey and. Pennsylvania groups are from his Dad, based on other matches at Family Tree DNA. I will report back if this new feature helps for his case.

The reason this may be helpful with adoptees is the ability  to separate matches into the different communities. Clicking on a specific community name gets you to a page with a map for that group and its history stories. There is an icon called Connection at the top left of the page (my red arrow in the image example to the left). Clicking it takes you to a page with information about your connections.

Family Trees are now linked to from the GEDmatch Tier 1 One-to-Many

Mar24

The new Tier 1 one-to-many at GEDmatch includes a link to your match’s family tree when that is available. Clicking the word GED next to that kit’s email address takes you to the tree your match has uploaded to GEDmatch. The word WIKI links to the compact tree view at WikiTree.

GEDmatch GEDCOM link

Clicking on the GED for a match takes you to the profile of the individual in the linked tree at GEDmatch.

Here is what you would see if you clicked on the GED next to my Dad’s name. Note the words “GEDmatch Ref: “ followed by a long number. That number is the id of this GEDCOM which you can use to compare to your own GEDCOM in the “2 GEDCOMs “ function on your home page.

Of course, I immediately click on the pedigree button in the little menu at the top of this individual page and then look through the pedigree on the next page for familiar names and places. Here is what the top half of my Dad’s tree looks like at GEDmatch. Note the default number of generations shown is 5. You can change that to a larger number (I often go to 8) and then click submit to see more generations.

WIKI link

Clicking on WIKI next to a match in the Tier 1 One-to-Many listing takes you to that match’s compact pedigree at the collaborative world tree WikiTree. This is automated and the connection to Wikitree happens because a member of that site has added a GEDmatch kit number to a profile there. Here is the top piece of what you see when you click on my WIKI.

GEDmatch Tag Groups plus new One to Many

Mar20

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.

Tag Group Selection in beta One-To_many, my purple outline

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.

The Power of Ancestry DNA circles

Mar14

My cousin DM got a new 3rd cousin match, DB, on her Ancestry.com DNA page that was listed in two of her DNA circles even though those ancestors did NOT appear on that match’s tree! Wow, is ancestry really able to make this call just from the DNA? There is no shared ancestor hint with my cousin. (By the way, each member of the couple who provided the DNA gets their own circle; in this case Sigri and Bard Nelson.)

After looking at DB’s tree I see that he has a Selmer Nelson on his tree who is a known descendant of the couple Bard and Sigri Nelson(Nielsson) who make these two circles. So he clearly does belong and his tree just does not go back that far.

Using the shared matches tab on this match’s page, I find that this new match, DB is in common with yet another match in these two DNA circles, BK with whom he is more closely related; they both have Selmer Nelson as a grandfather. BK does not have a green leaf with my cousin JM because he has spelled Bard Nelson and Sigri differently.

However BK is also a shared match with DK who DOES have a green leaf DNA ancestry hint with my cousin. DK shares Selmer’s dad J.B. Nelson with DB and BK. Aha, perhaps that is how this was figured out. Both BK and DK have Bard Nielson in their trees but DK spelled it the way we did. Now perhaps I understand how Ancestry put DB and BK in these circles!
