An amazing new Auto-Clustering tool from Genetic Affairs is the latest tool available to aid genetic genealogist in building genetic networks. The leaders in Genetic Genealogy have all been blogging about it. If you're interested in learning more about it, check out the links included at the end of this post.
This tool allows me to "drill down" in my matches at Ancestry where I have over 2500 4th cousins or closer. I've run several reports using varied settings. The example shown below was done with the settings at option A and amounts 40cM-15cM. It's having timing out issues right now due to size and my double colonial ancestry but this is really great output despite that. Below is an annotated screenshot of the output. I've not included the DNA Matches names which run across the top and down the left margin of the report. This is just the top portion of this particular report. There are a total of 68 clusters in this report.
The report also includes a match data table that is very helpful. If you keep good notes you will have a much easier time figuring out what groups each cluster represents. For the last few years, I have been sorting my AncestryDNA matches and attributing them to one of my 4 grandparents(noting PGF, PGM, MGF, or MGM in the Notes). This has helped me tremendously. Below is an example of the table data for my Cluster 14(not shown in the chart above)
I believe that each person's results will vary depending not only on their settings but also on their family dynamics and the number of family members(both close & distant) who have tested.
