No tree? No worries! If your DNA match only has a small tree, this post will help you, too.

Towards the end of this post, you’ll read an important tip for making it easier to identify your “treeless” DNA matches in the future. Don’t miss it – it might save your future-self hours of work!

Top five ways to learn about your Ancestry DNA match with no tree

The following are the top five tips for learning about your Ancestry DNA match and figuring out how they are related to you.

How much DNA do you share with your match?

When you are trying to figure out who your DNA match is in relation to your family tree, the first thing that you should do is understand exactly how much DNA you share.

Understanding the amount of shared DNA can help you estimate your relationship with your match. Once you have estimated your relationship, you will know approximately how far back in your mutual trees you should look for a connection.

The DNA that we share with our matches is measured in centimorgans, and you can find this information on your DNA match list or on their DNA match profile.

In the image below, you can see the DNA shared (in centimorgans) that I share with one of my cousins:

In this image from Ancestry DNA, you can see how many centimorgans I share with one of my DNA matches.

As you can see from the image above, I share only 43 centimorgans with my DNA match. These 43 centimorgans are spread across 3 DNA segments, which likely means that we are distant cousins.

In order to figure out how I am related to a distant cousin, I will need to know a lot about both of our trees. The connection might be hard to spot.

Check your DNA match’s profile for an unlinked tree

Now that you understand more about how much information you need to learn, you can start to explore the resources available to you to see what you can discover.

Many people who do DNA tests with Ancestry DNA don’t know that they can build a family tree and attach it to their DNA results.

If your DNA match has a family tree that is unattached to their DNA results, it will show up in your DNA match list like this:

how to know if your dNA match has an unlinked tree on ancestry dna
In the image above, you can see “unlinked tree” next to my DNA match’s name. This means that they have a family tree on their account that is not linked to their DNA results.

It is important to keep in mind that your DNA match might have family trees on their account that are not theirs. They might build trees for friends, relatives, or even professionally.

This means that an unlinked tree may or may not provide useful or relevant information to your family tree. It’s still worth checking, though!

I have found lots of useful information on my DNA matches unattached family trees.

Contact your DNA match

It’s time to grab the last of the low-hanging fruit. There is one more easy thing you can do to learn a little bit about your DNA match’s family tree:

Send them a message via the Ancestry DNA message button on their DNA match profile.

You don’t need to have an Ancestry DNA subscription if you click the contact button from your DNA match profile. If you try to contact them from their Ancestry profile, you do need a subscription.

If you contact your match, you might find that they are wiling to share the names of their grandparents with you. I’ve even had matches offer to send me pedigree charts.

You never know until you ask!

Your message should be very polite, and I would also suggest offering a little bit of information about your own family tree. If you have figured out which side of the family your match is on, you can provide them with some of the surnames in your family.

Shared matches with family trees

Hopefully, you’ve learned a little bit about your DNA match at this post. Now, you can start to explore your shared matches to see if you can spot patterns or links between your shared matches.

In the image below, you can see how to access your Shared Matches on Ancestry DNA’s new DNA match profile:

how to find shared DNA matches on the new Ancestry DNA match profiles
You can see the “shared matches” tab circled in red on the new Ancestry DNA match profile. Shared matches can help you figure out which side of the family your match is on, as well as other details

The top matches that show up on the “Shared Matches” tab will be the most helpful to you.

Check through the matches to see which matches have trees attached to their DNA results, and see if you spot any surnames that you may have already seen in connection to your DNA match.

This process is like a puzzle. Each detail makes up a new piece!

Family tree posted on another site

Your DNA match may have a favorite website where they prefer posting their family tree. They might even have their own family tree website!

You can check other sites where you have uploaded your DNA to see if they also show up as matches, or popular websites for building family trees.

You can also check for family trees posted by matches that you both share in common.

Building your family tree “wide” can help you learn about your DNA matches more easily

At this point in this post, you may have noticed a common thread: Family trees. They are key to our research as genetic genealogists.

Most, if not all, of the best ways to learn about your DNA match (whether they have their own tree or not) is finding a family tree that contains information about their immediate or extended family members.

I recommend that as you learn about new DNA matches, add them and their ancestors (those who are descended from your common ancestor or ancestors) to your family tree. The process of adding these extended relatives to our tree is called building a tree “wide“.

Note: Just be sure to mark living people as “living” in your Ancestry DNA family tree to protect their privacy!

The process of adding the children, grandchildren, and great-grandchildren (and so on, and so on) of the siblings of your ancestors to your family tree is called building a “wide” family tree.

In addition to having a more complete family tree, there is one additional benefit to this:

  • The wider your family tree, the more easily you will be able to identify more DNA matches in the future

Can you learn anything from a 0.1% DNA match? I have a few thousand of these and many go to the USA. I have been in touch with a few whose family trees show nothing connected to England for at least 300 years. Our trees do match but they can go back to 1500. I have 7 DNA matches with people who share the same great x9 grandparents and who have 0.1-0.3% matches. I was led to believe this was not possible. Also, I have used many sources in researching my tree; I even read the entire Warwickshire Antiquities to confirm a couple of links (and because it was interesting) but there must be many that I haven't even heard of. Can you recommend any that are free to use online?
