AutoTree

AutoCluster first organizes your DNA matches into shared match clusters that likely represent branches of your family. Everyone in a cluster will likely be on the same ancestral line, although the MRCA between any of the matches and between you and any match may vary. The generational level of the clusters may vary as well. One may be your paternal grandmother's branch, another may be your paternal grandfather's father's branch.

By comparing the trees from the members of a certain cluster, we can identify ancestors that are common amongst those trees. First, we collect the surnames that are present in the trees and create a network using the similarity between surnames. Next, we perform a clustering on this network to identify clusters of similar surnames. A similar clustering is performed based on a network using the first names of members of each surname cluster. Our last clustering uses the birth and death years of members of a cluster to find similar persons. As a consequence, initially large clusters (based on the surnames) are divided up into smaller clusters using the first name and birth/death year clustering.

Here is an example output that was employed using matches between 600 cM and 50 cM.

Reconstructed trees

Using common ancestors and their descendants, AutoTree reconstructs genealogical trees. In this example, the descendants of J Balentine are visualized. Some of these descendants are common ancestors as well. At the far right, the linked DNA matches are displayed (in red, using a color gradient).

AutoCluster visualization

Shared matches that have a common ancestor are easily detected in the AutoCluster visualization by the Christmas tree visualization. The overlay will show wich common ancestor has been identified.

Overview

The overview of these analyses is displayed in the main AutoCluster HTML file in a table. For each AutoCluster cluster as well as the combined set the number of common ancestors, common locations (for two distances) and common surnames is shown. The fields of the tree, common ancestor and common location are clickable and will show more detailed information.

Common Ancestor Overview

The complete list of common ancestor clusters with information regarding the underlying tree persons, their spouses, descendant and linked DNA matches is available in the common ancestors table.

Common Locations Overview

Using the birth location information from tree persons, we calculate location clusters using a minimum location distance. These clusters are available using the common location table which contains the location, linked tree, linked DNA match and the tree persons that linked to this location.
