How to Use 23andMe for Genealogy

Share the knowledge!

If you tested with 23andMe, you might wonder if your results can be used for genealogy. Rest assured, your 23andMe results can be very informative for genealogical research. In this post, I’ll teach you how to use your 23andMe results to build, or expand, your family tree.

Which element of 23andMe results is most helpful for learning about your family tree?

While all aspects of your 23andMe results are interesting and informative, the element that is most helpful for building your family tree is the DNA relatives list. This list is otherwise known as your DNA match list.

DNA matches are like valuable gems when it comes to family tree research. Once we learn how we are related to our DNA matches, we can add their family lines to our family tree. Sometimes, our DNA matches have done more research than we have about our shared ancestral lines, and their family trees can help us build our trees even further back.

How can your 23andMe DNA matches help with genealogy?

Some of the information we can learn from our DNA matches will be readily available, written by them and noted directly on their profile. Other times, we might have to dig a little bit to determine how we are related to our matches, and what we might be able to apply to our family tree.

Find out what your 23andMe DNA match includes on their profile

The first thing you should do is try to find the information directly listed on your DNA match’s profile. The type of family tree information that you might find on your DNA match’s profile includes:

  • Birth place of maternal and paternal grandparents
  • Birth places of other ancestors, if known
  • Surnames in family tree
  • Link to family tree

It is important to note that 23andMe doesn’t require users to include this information, and some of your DNA matches may not know enough about their family history to do so. Additionally, not everyone is aware that they can include a link to their family tree on their 23andMe profile.

If you do get lucky and find DNA relatives who have included this information on their profile, that’s great! It means that they know something about their ancestry, and they might be interested in learning more by connecting and sharing information with you.

This is a great opportunity to check your own profile to be sure that you have included as much information as you can.

How 23andMe matches can help you build your family tree

I hope that you have already begun building your family tree (I recommend Ancestry for building trees) on another site. As you learn about your DNA matches, you can add their family lines to your tree.

For example, if you find a third cousin on 23andMe, and identify that your great-grandparents were siblings, you can add these individuals to your tree:

  • Your great-great grandparents (if they aren’t already on your tree)
  • The sibling of your great-grandparent
  • Other siblings of your great-grandparent, if you learned about siblings who were previously unknown to you
  • The grandparent of your DNA match who is descended from your common ancestor
  • The parent of your DNA match, if known
  • Your DNA match, and their children, if possible

By identifying your connection to only one third cousin, you will add at least 4-6 people to your family tree, and perhaps even more!

This family tree building technique is sometimes called “building your tree wide“, and it is the best way to build a complete family tree. It also makes it easier to identify your connection to other DNA matches in the future.

I’m putting together a post specific to determining how your 23andMe DNA matches are related, and I’ll update the link once it’s done 🙂

Can the 23andMe Ancestry Composition help you with genealogy?

I always stress that 23andMe DNA matches are the most helpful aspect of DNA results when it comes to genealogy, but that doesn’t mean that your ancestry composition report won’t help you at all. There are a few ways in which your ethnicity estimate can, indeed, point you in the right direction when it comes to building your family tree:

  • Ancestry regions shared in common with your DNA matches can help you determine how you might be related, or help you determine how you are not related
  • 23andMe gives very specific ancestry composition reports, and if you have significant ancestry from a particular region, you might see this indicated on your 23andMe ethnicity estimate. This can help you focus your research
  • Unexpected regions can help us know which lines of our tree need more research

Upload your 23andMe data to other sites to learn more about your family tree

23andMe allows you to download your raw DNA data, which can then be uploaded to other websites. These other sites can provide you with more DNA matches and access to DNA analysis tools.

My favorite sites to upload to include:
