DNA Cousin Matches Can Lead to Family History Discoveries

February 22, 2019  - by 

DNA testing has become a big part of genealogy and family history. DNA matches, sometimes referred to as cousin matches, can be the link to overcoming brick walls in family history research, help adoptees find their birth families, and lead to exciting new family history discoveries.

DNA testing companies that assist with family history generally offer DNA matches or cousin match lists in their DNA testing reports. These DNA cousin matches are a list of people whose DNA matches yours significantly. Depending on how much of your DNA matches, the report can give an estimate of how closely you are related.

Each of the DNA matches on your list may possibly have a common ancestor or ancestral couple from which you both descend. Once you have a DNA match, you may be able to collaborate with your newfound cousin to find this common ancestor, work together on holes in your family tree, or share family history stories and pictures.

3 Steps for Using Your DNA Cousin Match List

    1. Review the family tree of each of your DNA cousin matches, if a family tree is available. DNA cousin matches who are familiar with family history will likely have an online family tree associated with their DNA test results. At the least, they may have included where their ancestors lived and a few of their most recent surnames.

  1. Use the family trees, surnames, or other information to guess which DNA cousin matches are on your father’s side or your mother’s side of the family.
  2. Start contacting your DNA matches via your testing company’s internal message system.

Note: It’s important to remember before reaching out to your DNA cousin matches that not all people who participate in DNA testing are knowledgeable about their family history. In fact, many people send in their DNA just for fun or to learn about their ethnicity breakdown. For this reason, some of your DNA cousin matches may not be able to collaborate with you as easily regarding your shared ancestry.

Which DNA Cousin Matches Should I Contact?

Typically, a DNA cousin match list will begin with your closest DNA matches first. The list is usually categorized by immediate family, 1st to 2nd cousins, 3rd to 4th cousins, and distant cousins, although each testing company’s categories vary. It is important to learn exactly how your testing company categorizes their matches.

Contact your closest matches first. The easiest way to contact a DNA cousin match is via the testing company’s message system.

Not sure what to say? Here’s a helpful example:

“Dear ____, It seems that you and I are close DNA matches. I noticed you did (or didn’t) have a family tree uploaded and wondered if you would feel comfortable sharing a little of your family history with me. I am the daughter of Jacob Smith and Ann Donnelly. I believe you are likely from the Smith side of my family. My father Jacob (b. 1941) is the son of Michael Smith (b. 1911) and Donna Mason (b. 1913) of Sandusky, Ohio. Do any of these names sound familiar to you? I am hoping to learn more about Michael and Donna Smith and hope you might have some information. Hope to hear from you soon.”

As you move down your list to 3rd, 4th, and even more distant cousins, it may become more difficult to determine how closely you are related or who the common ancestor is. But those matches shouldn’t be overlooked. Reaching out to these more distant DNA cousins may still be beneficial.

Collaborating on Family History with Cousin Matches

As you contact cousins, it may be helpful to offer your own information about shared relatives in exchange for what they have. This offer can help you and your newfound relatives build your family history together.

If your DNA matches don’t yet have a family tree, helping them sketch out a small family tree may be a good way for them to share information they have about their parents, grandparents, and other relatives. Most cousins will remember parent and grandparent names and places.

Lots of great tools are available for building a family tree for your cousins or yourself. When you create a free account on FamilySearch.org, you can use the shared FamilySearch Family Tree to build your tree, search for records, and work together with your cousins and other family.

Whether you found the information you needed in your first contact with your cousin matches or didn’t learn as much as you had hoped, consider reaching out again, even regularly, to share new information and see if these relatives have learned more as well. Record what you know in your family tree so you and others can connect with your ancestors and preserve your family stories.

In 2018, Donna decided to participate in DNA testing in hopes of finding her relatives. With the help of a professional genealogist familiar with DNA testing, she was able to find a first cousin match. After reaching out to this newfound cousin via the testing company’s internal message system, Donna found family members willing to work on family history with her. Shared stories, family hobbies and interests, and pictures have just been the beginning of this amazing family history discovery.

If you have taken a DNA test, be sure to upload your family tree to the testing website. You may discover DNA cousin matches for yourself, or you may be the DNA cousin that leads to a long awaited and much anticipated family history discovery!

  1. Since I was nine years old and my mother told me she was in orphanages from the time she was a toddler till she was six years old and was fostered, never adopted , and did not know who her parents were , or what her birth name was I have been determined to find who they . I greatly missed not knowing my grandparents on my mother`s side were , and I can only imagine what a loss it was for her. She went by the name Margaret and grew up in Loyal , Oklahoma . We think she was born in 1914 or 1916 , maybe in Dallas , Texas . She tried to find out who her family was during the 1940`s but there were no DNA tests then , so she never found out . I have taken 2 DNA tests , one with Ancestry.com and one with 23 and me and have learned more than she ever got to know . We believe her parents might have been from the Williams family . I am currently searching for a birth certificate or any information that would prove our guess . I did pay for an individual from the family to take the DNA test and they came back as a high match , and a sibling of theirs took the 23 and me test and showed up as a high match of mine . I called Catholic Social Charities to try to find any information but, they won`t tell me if they even have any information without hiring an attorney , therefore without these incredible DNA tests , I would still not have any idea of who my mother`s family was .

  2. I recently had my DNA tested, and was soon contacted by a 3rd cousin who remembered visiting my grandparents with her grandmother! We both feel as though we’ve hit a jackpot, as we continue to share information and make new discoveries about our (previously seemingly elusive) family. I would strongly recommend DNA testing to everyone!

  3. I had a very unexpected find back in 2012 when I took my DNA test. My last name is Oliver, but I found out my Dad was adopted by his father when he was 1-1/2 years old. Nobody but my grandparents and their immediate family knew this. I found out who my biological grandfather was, discovered my Dad (who had already passed and thought he was an only child) has two brothers who are still alive. I have had the great pleasure of meeting my one uncle and building a nice relationship with him.

  4. My father’s sister married my mother’s brother. Two marriages within the same two families. Will my first cousin and I have similar DNA like my brother & I? Will my cousin appear to be my sister? Thanks for any comments.

  5. Igot this site from my friend who told me regarding this site and now this time I am visiting this website and rearing very informative articles here.

  6. I am searching for early (1600-1700)France ancestry for Gauche brothers, who shipped out of England to American Colonies, and helped fight the British.
