How Do I Read My DNA Match List?
Looking at Your DNA Matches Can Feel Overwhelming
Whether you've tested with AncestryDNA, 23andMe, MyHeritage, FamilyTreeDNA, or another DNA testing company, opening your DNA match list for the first time can feel exciting—and confusing.
You may find yourself wondering:
Who are all of these people?
Why don't I recognize any of these names?
What does "shared DNA" mean?
What are centimorgans?
How do I know who is important?
The good news is that you don't need to understand everything at once.
Learning how to interpret your matches takes time, and help is available.
What Is a DNA Match?
A DNA match is someone who shares enough DNA with you to indicate a biological relationship.
The amount of shared DNA helps estimate how closely you may be related.
The closer the biological relationship, the more DNA you will typically share.
DNA testing companies use this information to estimate possible relationships, but these estimates are just that—estimates.
Additional research is often needed to understand how someone fits into your family tree.
What Are Centimorgans (cM)?
Centimorgans, often abbreviated as cM, are a unit used to measure the amount of DNA two people share.
Generally speaking:
Higher cM totals usually indicate a closer biological relationship.
Lower cM totals often represent more distant relatives.
However, many relationships overlap in the amount of DNA they can share.
For example, the same amount of shared DNA could represent several different biological relationships.
That is why DNA should always be considered alongside family trees, ages, locations, and other available information.
Don't Focus Only on the Closest Match
It's natural to focus on the person who shares the most DNA with you.
But sometimes the answers come from looking at groups of matches rather than a single individual.
Patterns often become clearer when multiple relatives are considered together.
Genealogy is often like putting together a puzzle.
Each match provides another piece of the picture.
Family Trees Can Provide Important Clues
Many DNA matches include family trees.
These trees may help identify:
Shared ancestors
Family surnames
Geographic locations
Migration patterns
Connections between different DNA matches
Not every family tree is complete or accurate, but they can provide valuable clues for further research.
Remember That DNA Doesn't Tell the Whole Story
DNA can identify biological relationships.
It cannot explain family circumstances, relationships, personal histories, or the experiences that shaped people's lives.
Learning new biological information can answer some questions while raising many others.
Give yourself permission to move slowly as you gather information.
You Don't Have to Figure It Out Alone
Interpreting DNA matches can feel complicated, especially after an unexpected DNA discovery or while searching for biological family.
