Fun New Features at Ancestry DNA

I really like a number of the features that have come out recently at Ancestry. My favorite is that the total amount of DNA shared with each DNA relative is now shown on the match list page in centimorgans (cMs). This means that you no longer have to click through to the match page to find that number. Those total cMs are needed in order to look up the possible relationships at the DNApainter calculator. You want to check there because the cousin designations at Ancestry are just groupings based on the amount of DNA and many relationships share very similar cM numbers.

Look at the current top of my 2nd cousin list. These are all children of my first cousins except C.S. who is the grandson of a first cousin. (spot quiz – what is my relationship to each of them? Answer at the end of this article). In each case it shows not only the possible relationship but also the actual cMs and the number of segments.

The other recent feature that I truly appreciate is that Ancestry.com indicates whether there is a family tree linked to the DNA, a tree that is not linked, or no tree at all next to the View Match button. In the past there would only be a tree listed when it was linked to the DNA, so you had to go to the match page to see if there was a family tree that was just not connected to the DNA. A word of warning about unlinked trees, they may not be for the tested person. One of my real second cousins did his DNA test through a friend’s account so he is not in their tree at all!

Did you notice that little blue compare icon under the green View Match button? Click on that to get a comparison of the ethnicity of two tests. It always fascinated me to see the amount of difference between two full siblings. Here I am compared with my brother (click it for a larger version).

A word of warning. A friend complained that his sister only had a tiny amount of XYZ heritage while he had a good 33%. I pointed out that her ethnicity had not been updated to the new version. Once that was done, she had a bit more XYZ than him!

Another benefit of this comparison is the much larger versions of the profile pictures which are on top of the ethnic breakdowns on that page. Space considerations got me to cut them off in my image above. However it is quite nice to get a better idea of what your match looks like than you get from the tiny picture on the match page.

Now for a discussion of the new traits feature …

Finally, Ancestry’s New Ethnicity Estimates

Today we all got an email from Ancestry announcing new ethnicity reports for everyone. Adding five times the reference populations plus a better algorithm that can often indicate the modern countries. This time I really do have the new ancestry composition estimates!
Updates Available box
Naturally I immediately went and looked. Then I messaged and emailed all my tested cousins to accept the new update. When you log in to Ancestry and click on DNA in the top menu you get a page with three panels. Click on the panel to the left called “DNA story” to go to a page with a world map and the Updates Available box on the upper right.

Click the green button that says View your Updated Estimate in that box. Next you have to answer a few questions about your expectations and your thoughts on the previous ethnicity. I am afraid I did not understand that below each was a slider which I could move to indicate the level of accuracy, so until the last one that I answered, I left it alone. I wonder how many others will make that error.

The first time on your new ethnicity page, you will see a panel on the right showing how your estimates have changed. Here is mine. I was sad to say goodbye to that unlikely 1% Polynesian!

My father was Norwegian American with one fourth grandad (2% of his DNA?) who was German. My mother was born in Munich to a Jewish father and Bavarian Catholic mother. So how does that play out in these new estimates? Could the Swedish be a remnant from the 30 years war where Swedish soldiers rampaged through Bavaria? Actually I think my Norwegian dad had a fifth grandparent who was Swedish but that would hardly show either.

Here is my brother’s  page showing the new estimates with the changes:

I am still 29% Jewish but my brother is down to 20% from 22%. Our maternal grandad was Jewish and I randomly got more of his DNA than my grandmother’s. When a 2nd cousin on our maternal grandmother’s side tested, my brother did indeed share a third again as much DNA with her as I did (Click here for that post)

By the way you can get back to the page showing the changes together with the new estimates by clicking on the small blue Updates at the top of your ethnicity estimate then the View Previous Estimate at the bottom of the Ethnicity box followed by Compare these results to your most recent AncestryDNA estimate on the next page.

Now to look at some more interesting ethnic makeups from my cousins and people I have helped.

An Awesome Ancestry Add-on

One thing I have always wanted when looking at my ancestry DNA matches was to list just the unstarred matches or matches that I have identified as being on a specific line. Well there is a new add-on for chrome called MedBetterDNA that will do that for you now, among other great features. Thank you Blaine for mentioning it in your Genetic Genalogy Tips and Techniques Facebook group today.

Another thing I love from this add-on is that it displays the notes you have made for this match directly on the match page so you no longer have to click each little notepad. Here is what my brother’s page looks like now:

Notice the little multi-colored people icons next to the green leaves? That is from another chrome add on called the AncestryDNA helper and a mouse-over on those icons shows the DNA relatives in common, but that is another blog post not yet written.

How to get your ancestry match to respond

Most of the time when you send a message to a DNA match at ancestry you get no response. I used to assume that their membership had lapsed or that they had not logged in and seen their messages, but it turns out, that may not be the reason at all.

The real reason is that many people are using the Ancestry App on ipads, tablets, or smartphones and the Ancestry App does not show your messages. I was shocked when I finally got this response today from a match.

The last date that someone has logged in shows on the match page and I had seen that this person was logging in regularly, but it was from their tablet! So everyone who uses the app please complain to customer service at Ancestry.

So how did I get his attention? I left a comment on an ancestor on his tree with a link to the find-a-grave entry! The next day I got the message above. Leaving a comment always generates an email which finally gets their attention.

Using Ancestry DNA hints to prove and disprove ancestors

With over 4 million DNA tests [as of 11 aug 2018 – 10 million], the Ancestry database has reached a tipping point where any tester with American ancestry will get some good cousin matches. How do these help prove an ancestral line? Well when your DNA matches multiple people descended from the same ancestral line, you can have some confidence in that part of your tree. Conversely, if you have no matches on a line, there may be a problem.

On your DNA home page, the center panel summarizes your match count. It shows the number of predicted 4th cousins or closer as well as the number of starred and green leaf ancestors. You can add stars to matches for whatever reason you wish. Only you and anyone you share your DNA results with can see them. Ancestry will indicate each DNA match that also has a tree match with you by using a green leaf.

Ancestry DNA Home Page Center Panels (words in red are mine)

Notice the big difference in the number of cousins between those with 19th and 20th century immigrant ancestors like my family and those with deep American ancestry. Also foreigners like my Norwegian cousin will have very few, while Jewish testers will have incredibly high numbers due to endogamy.

DNA Matches Page

Click on the green View All DNA Matches button to get to your DNA matches page. Or click on the starred or green leaf matches to see just those matches. On your match list page, every DNA match who also has a matching ancestor to you in their tree is marked with a green leaf indicating a hint.

When there is a green leaf, clicking on the View Match button will take you to a page that will show you a picture of the expected relationship pathway (images of that on page 2 of this article).

Many times matches with no tree will actually have a tree that is just not connected to their DNA. You can see that on the view match page. There you can select it in the dropdown menu, as shown below, to get the usual sideways display with a surname list. Sometimes you can even figure out where they fit in from it.

I like to make Ancestry do the work of checking my assumptions by adding the tentative line to the tree connected to the DNA test. I put a “??” as the suffix when I am trying out a set of ancestors so that anyone copying my tree is warned that it is a test. Strange characters in the suffix box do not seem to affect the matching. Another perhaps better solution is to make your tree private while you experiment. Or to use a second small private tree that you connect your results to when trying out a possible ancestral line. You can change what tree and who your DNA is connected to on the DNA settings page. Get there from the button with a gear on the top right of your DNA home page.

Here are some examples of my experiments.
