Make Ancestry Find the Relationship

Did you know that Ancestry can figure out how you are related to a DNA match if you both have trees linked to your DNA tests? You do not have to have anyone further back than your parents if other relatives have more extensive trees on Ancestry that include your family,

So how do you link your tree to your DNA? First log into Ancestry.com. Then click on DNA Result Summary in the pull down menu under DNA. Next click the gear on the far right that says Settings next to it as shown in the image below.

Once you are on the Settings page, scroll down to the words DNA and family tree linking.​ Then click that box to get to the page where you can link your test to your tree.

​There you will see something like the below image​ where you can specify the tree and the person to link the DNA test to. When you start typing a name, Ancestry will use auto complete to show possible names from your tree. Once you have selected yourself or the person whose kit it is, click the blue button to make the connection.

The tool Ancestry uses to find and display relationships based on trees linked to DNA results is called ThruLines which I have numerous posts about. Now for an example of what this can produce.

Who is my great great grandfather’s daddy? A ThruLines experiment

My great great grandfather Jørgen Oleson Wold, 1816-1892, from Skougar near Drammen, Norway, was born 9 years before his parents tied the knot. Although his father is listed as the man his mother eventually married, DNA testing has stirred up my doubts.

Having a child out of wedlock was not uncommon in rural Norway of the 1800s. It was not considered shameful in many areas. Often the couple would marry later on; you had to be able to support a wife in order to have one. Another reason is that people wanted to be sure they could have children before marrying, since many hands were needed on the farm. The data shows that quite often women were pregnant at the altar. Click here for an article showing that having a sexual relationship and getting pregnant was the normal way to start a marriage in at least one area of Norway at that time. Night visiting, fully clothed, was a customary way for young people to get to know each other.

According to the 19th century clerygyman and sociologist Eilert Sundt (my 10th cousin 3R), who looked carefully at many population statistics, 43% of all Norwegian children were conceived before their parents got married back in the mid 1800s. Click here for the article that cites this.

The problem for Jørgen’s parentage is that there are no DNA matches on just his father of record’s line. It is always possible to get less DNA from one 3rd grandparent but it seemed that all my family’s matches to the descendants of other children of that marriage were smaller than expected. We also have many matches quite far back on Jørgen’s wife’s line, suggesting it was possible we just had more DNA from her side but also demonstrating that when there are many generations of large families, DNA matches to 5th and 6th cousins will be found. This is also true on our other Norwegian lines.

Could Jørgen have a different father? If so, I would expect to see a group of 4th cousin matches who match each other but are not assigned to any of our known lines. Since Norwegian records are good, our ancestors are well documented back into the 1700s or even earlier.

There is a large group of matches that fits that scenario, all descended from one Torkild Westby b 1810, Drammen, Norway. It so happens that Westby/Vestby is a farm in Skoger just outside of Drammen where Jørgen may have lived as a youth. Norwegians did not have surnames back then, they used their father’s name plus their farm of residence which could change. Also W was pronounced as V in Norway so they are interchangable in the spelling. When Torkild’s children came to America they used the surname Westbye. I found the birth record for Torkild in the Norwegian archives and sure enough, he was born on farm Westby in Skoger..

I decided to try a ThruLines experiment by changing Jørgen’s father to Torkild’s father, Jahn Jahnsen Westbye, in my Ancestry tree and see what happened. For Jørgen’s father and grandfather of record, Thrulines listed no DNA matches that were not also listed for his son.

Ancestry’s new DNA feature: ThruLines

Ancestry.com announced a great new tool at Rootstech called ThruLines. It finds connections to your DNA matches by looking through other people’s trees for you. This replaces DNA circles by displaying the descendants of your ancestors in a more understandable format. Even if you have a private tree, you will get these ThruLines as long as your tree is set to searchable. Here is what the new DNA overview page looks like:

ThruLines is fabulous but a little buggy. I was constantly getting page not found apparently due to a cookie problem and was wondering if I would ever finish this post! A trick suggested in Blaine’s DNA tools group on FaceBook solved this for me. I now open the ThruLines page as a private or incognito page by using the right click menu in Firefox or Chrome.

Right mouse clicking on ViewDNA matches brings up a menu where you can request a private window

The ThruLines page shows images of each of your ancestors with whom you share DNA matches, ordered by most recent first. Since I have tested my brother and many first, second, and third cousins, there were no surprises in the first four lines (16 ancestors) but once I got back to my great great grandparents I found a number of new cousins that I had not found before on my Norwegian side: descendants of my Wold great grandparents and my Halling 3rd grandparents.

One of the nice things is that Ancestry can see past the private parts of trees to find the connections. It shows you living people as boxes marked private but can still connect them back to the common ancestors. It also indicates whose tree the information came from, which is helpful when you know there is an error since you can click on the tree name to see it and contact that person to request that they fix it.

I found a whole slew of new Halling cousins decended from my great grandmother’s sister Nikolena

I was about to complain that I would prefer to see these ThruLines theories start from my DNA matches rather than my ancestors when I discovered that if I joined the Beta test of the new matches page they do exactly that, among many other wonderful new features.
