First, a total number of 12200 DNA matches and 6162 shared matches were downloaded. The last DNA match (Nicole Hanlin) from this initial download shares a total of 6.0077 cM. Next, the AutoCluster analysis tries to download shared matches for as many DNA matches as possible. For 280 DNA matches we were able to download shared matches. We stopped downloading shared matches after the 280th DNA match (B.M. Katrina Murphy sharing 29.0 cM) since that match shares less cM than the minimum cM threshold. As requested, cM thresholds of 250 cM and 30 cM were used. A total number of 268 matches were identified that were used for a AutoCluster analysis. There should be two zipped CSV files attached to this email and if enough matches can be clustered, an additional zipped HTML file. The first zipped CSV file contains all matches that were identified. The second zipped CSV file contains a spreadsheet version of the AutoCluster analysis. The unzipped HTML file will contain a visual representation of the AutoCluster analysis if enough matches were present for the clustering analysis. Please note that some files might be displayed incorrectly when directly opened from this email. Instead, save the zip files to your local drive, unzip them and then open the files.

Note: The following 9 matches met the inclusion parameters but were placed in an cluster without other members and so are not included in the chart: G.G. mgilbreth62, Loretta Penning, Craig Terkelsen, Connie Peabody, W.W. Patty Bueker, P.H. Aggie Henry, Miriam Mathews, ScotterMac, Lisa Rusyn

Explanation of AutoCluster analysis

AutoCluster organizes your matches into shared match clusters that likely represent branches of your family. Each of the colored cells represents an intersection between two of your matches, meaning, they both match you and each other. These cells in turn are grouped together both physically and by color to create a powerful visual chart of your shared matches clusters. * *

Each color represents one shared match cluster. Members of a cluster match you and most or all of the other cluster members. 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.

You may see several gray cells that do not belong to any color-grouped cluster. They usually represent a shared match where one of the two cousins is too closely related to you to belong to just one cluster. Each of these cousins belongs to a color-grouped cluster, the gray cell indicates that one of them belongs in both clusters. Unfortunately, the underlying code does not support multiple cluster membership.

Although every attempt is made to include every shared match triangulation that falls within the user selected parameters, there is no guarantee that all such triangulations are included in any AutoCluster matrix or in the corresponding data table. Please verify all match instances and characteristics at the original test site. And, as with DNA evidence in any format, no genealogical conclusions should be drawn based only upon data found within any AutoCluster output.
