Discovering your DNA Family

A Practical Guide to Finding your Family using Ancestry DNA


Working with DNA is like a jigsaw puzzle.  If you were building a jigsaw of a beautiful tropical beach you would need a methodical approach.

Divide your Matches into Groups
  • Add notes to help you remember what you’ve discovered about each match.
  • Identify matches from your known family to separate Maternal/Paternal matches (if possible).
  • Identify groups of Shared Matches and create/apply Ancestry Colour Coded Groups – see here.
Look for patterns within each Shared Match Group
  • Try to find “Significant Ancestors” (ancestors who appear in several trees within a group).
  • People who are your matches’ ancestors they are likely to be your ancestors too – or should lead you in the direction of your Direct Line Ancestors.
  • If you can’t find Significant Ancestors, look for other patterns – eg, surnames or locations.
Build your Research Tree
  • Recreate the trees of your matches within your Research Tree.  Use your Research Tree to work out how your matches are related to each other and who they share as common ancestors. 
  • See here for instructions on creating Floating Branches and here for some tips and tricks on managing your Research Tree.
  • If you have matches who do not have a tree (or have a very small tree), build it for them.  See here for ways to work out who your matches are, so you can research their family history.
  • If you’ve copied a match’s tree and it doesn’t make sense there could be errors in the tree you’ve built/copied, or perhaps the paper records are concealing an adoption or misattributed parent(s).
Connect the Floating Branches
  • In a simple world, someone from one Shared Match Group would marry someone from another.  One of their children would go on to marry someone from another group and “all” you need to do is move through the generations, connecting the Floating Branches until you reach your parents.
  • Making the final connection can be the hardest step – getting stuck at the “which brother is my Father?” stage is not unusual.  You may need to persuade relatives to test to reach a conclusion.

Ancestry DNA Match List

Ancestry’s DNA match list, and the trees created by your matches, are the starting point for discovering your own DNA family.  

It can be difficult to know where to start when you’re offered so much information at once.  Today’s information sheet guides you through the  information available within your match results.  It also shows you how to use the tools available for searching, sorting and filtering.
