Grouping DNA Matches
After taking a DNA test, most people have thousands if not hundreds of thousands of DNA matches. Clustering or building genetic networks is the process of grouping those matches based on which ancestor or ancestral line through which they relate. To create a cluster:


 * 1) Start with a match, if possible, determine your relationship
 * 2) Assign a colored dot (on Ancestry) or create a list of people in the cluster
 * 3) Use the shared matches feature to identify other matches who also share DNA with you and the match; add them to the cluster
 * 4) Repeat with other members of the cluster until the cluster has been mostly identified
 * 5) Name your cluster either using the name through which these people relate; if common ancestor is unknown, mark it as unknown

A cluster has been created.
