What Is the Leeds Method?
The Leeds Method, developed by Dana Leeds in 2018, is a color-coding technique designed to help organize DNA matches into family groups. This method works particularly well for individuals looking to identify unknown ancestors, verify family lines, or break through brick walls in their research. When I first started training, I wondered if using this method was worth it, but it is, I promise...
The goal of the Leeds Method is to group DNA matches by shared ancestors. It does this by identifying distinct clusters of matches that likely correspond to your four grandparent lines (maternal grandfather, maternal grandmother, paternal grandfather, and paternal grandmother).
Why Use the Leeds Method?
People choose to use the Leeds Method for several reasons:
Clarity: It simplifies a long list of DNA matches into more manageable groups.
Visualization: The color-coded chart provides a visual way to see how matches connect to different parts of your family tree.
Efficiency: It helps narrow down which matches to prioritize, saving time and effort.
Flexibility: The method works well for a variety of research goals, including solving adoption cases, identifying unknown ancestors, and verifying relationships.
How Does It Work?
The Leeds Method is relatively simple to implement. Here’s a step-by-step overview:
Start with your closest DNA matches: Exclude immediate family members like parents, siblings, or children. Focus on matches in the range of 2nd to 4th cousins with a cm between 90-400.
Create a chart: Use a spreadsheet or even pen and paper. List the names of your matches in the first column.
Assign the first match a color: Look at the shared matches for this person and assign the same color to all of them.
Move to the next match: If they don’t overlap with the first group, assign them a new color. Continue this process for each match.
By the end, you should have several color-coded groups representing different family lines.
Why the Leeds Method Works
This method is effective because DNA matches often share a common ancestor within a few generations. By grouping them based on shared matches, you can focus your research on specific branches of your family tree and identify how those branches connect.
Final Thoughts
The Leeds Method is a powerful tool for genealogists looking to make sense of DNA results. It’s straightforward, visually intuitive, and adaptable to various research goals. Whether you’re a beginner or an experienced researcher, this method can provide valuable insights into your family history.
