Welcome to Genetic Genealogy Links!
The links on these pages provide quick reference to several categories of genetic genealogy resources. This is a work in progress. We will add links and categories as we discover new resources, but we can't possibly keep up with all the changes in the world of DNA. If you have a suggestion for a new link or category, contact us at

DNAGedcom uses the Collins Leeds Method (CLM) Tool to generate a grid (often called a matrix) to show your matches arrayed in groups (clusters). Membership in clusters is based on matches sharing other matches in common (ICW) with your selected kit. Cluster members share a common line of descent within a few generations, often even the same ancestors.

GEDmatch offers Autocluster, Autopedigree and Autotree tools– developed by EJ Blom of Genetic Affairs. Autocluster: Allows users to group DNA matches of people who have a common ancestor and likely belong to the same branch of the family tree. Autotree: Takes the information from the Autocluster tool and identifies common ancestors and reconstructs genealogical trees based on information from the Autocluster tool. Autopedigree: Complements the Autocluster and Autotree tools by allowing the user to develop family tree predictions. The new tools are available for Tier 1 subscribers.

Genetic Affairs offers tools which group your DNA matches into clusters that most likely descend from common ancestors. These tools can help identify unknown ancestors (for instance an unknown great-grandfather) or assist persons with unknown parentage to discover their birth families.

AutoClustering organizes your MyHeritage DNA Matches into shared match clusters that likely descend from common ancestors. Each of the colored cells represents an intersection between two of your matches, meaning that both individuals match you and each other. These cells are grouped together physically and by color to create a powerful visual chart of your shared match clusters.

RootsFinder, owned by FindMyPast, is a family tree building and DNA analysis website. The premium level allows the use of DNA features and costs $5 a month. RootsFinder has a DNA feature called the triangulation (cluster) view, which allows you to view your matches in clusters – otherwise known as a network graph. In a network graph, the nodes are DNA matches and the connecting lines are shared match connections.

Shared Clustering is a tool that allows an advanced or expert genetic genealogist to extract more information -- and more useful information -- from Ancestry DNA shared match lists. Rather than providing a single list of matches ordered only by the strength of the match, Shared Clustering divides that list into smaller clusters of matches that are likely related to each other. Knowing which matches are related to each other can often be a huge help in figuring out how those people are related to you, the test taker.
