2020欧洲杯在线网址The shared matches list shows DNA matches that you and one of your DNA matches have in common. This might help you determine which family line you share or give you more evidence that you’re related to a specific person or match. For example, if you and your brother share DNA with a cousin, that cousin will show up as a shared match for both of you. Similarly, if you have a DNA match and your 2nd cousin has the same DNA match, this person would be a shared match to you and your 2nd cousin—and may help you determine how you’re related to this 2nd cousin.

Viewing Your Shared Matches

You can see your shared matches with another individual by viewing one of your matches and clicking the Shared Matches tab. You can sort and filter the list to help you find the shared matches you’re interested in. Shared matches work best for closer relationships so you’ll only see “high confidence” matches (4th cousins and closer to each of you) in the list (See how population changes affect how much DNA you share with others.)

2020欧洲杯在线网址It’s important to remember that you, your match, and your shared match won’t necessarily have the same common ancestor. Also, even though all three of you match each other, it isn’t likely that the three of you share the same piece of matching DNA (you probably match each other at different locations in the genome).

Using Shared Matches in Your Research

2020欧洲杯在线网址Shared matches can help you figure out how you’re related to a DNA match by narrowing down which family line you and your DNA match share. Here are a couple techniques you can try.

Find matches related to you through a specific family line

2020欧洲杯在线网址If you have close family members that have also had their DNA tested, their results can be extremely helpful in understanding your DNA matches. For example, if you share a particular DNA match with your mom’s cousin, it could be that you’re related to that DNA match through your mother’s line, which cuts your research in half.

This can be particularly useful if your DNA match doesn’t have a family tree or their tree is private. By looking at your shared matches, you may be able to identify which side of your family tree they come from.

The trick is to figure out which family members can help you narrow down your matches to the family line in which you are interested.

  1. Use the table to determine which close family member you need to look at.

    Look at this DNA Match To focus on this family line
    Mom, dad, aunt, uncle, 1st cousin (on maternal or paternal line depending on which side you’re interested in) Maternal or paternal line (½ of your tree)
    Maternal grandparent or 2nd cousin Maternal grandparent’s line (¼ of your tree)
    Paternal grandparent or 2nd cousin Paternal grandparent’s line (¼ of your tree)
    Maternal great-grandparent or 3rd cousin Maternal great-grandparent’s (⅛ of your tree)
    Paternal great-grandparent or 3rd cousin Paternal great-grandparent’s (⅛ of your tree)
  2. View a DNA match you’re interested in and click the Shared Matches tab.
  3. Use the filter, sort, and search features to explore which close family members are in your Shared Matches list and potentially narrow down your line of research for this match.

Determine if you, your match, and your shared match are related to a shared ancestor

Another way to use shared matches is to combine your shared matches and shared ancestor hints for clues on how you’re related to a specific DNA match.

  1. View one of your DNA matches that you’re interested in and click the Shared Matches tab.
  2. Click the Hints filter. Now the list only shows matches who have shared ancestor hints with you
  3. Click the View Match button next to your shared match to see which shared ancestor you have in common with this shared match. This can give you a clue on how you might be related to your specific DNA match.
  4. Look through your matches to see whether any particular shared ancestors or family lines are more common.

Once you’ve narrowed down the family line where you and a particular match may have a shared ancestor, dig in to see if you can find more evidence.
