AncestryDNA Custom Match Clusters Released Tuesday, October 21

Late this Summer those AncestryDNA users with the extra AncestryDNA Pro Tools received the DNA Clusters tool. We announced the roll out in our July 4th post. There is an Ancestry Blog post on the release here.

Yesterday, October 21, Ancestry released the Custom Clusters aspect of the DNA Clusters tool. You can read about it and how to utilize it in yesterday's Ancestry Blog post. Or in a Support Topics post on Custom Match Clusters


DNA Clusters visually presents your matches so you can see these matches as a group showing how they relate to each other -- which match matches which matches. These cluster groups can often be identified by the test taker's grandparent lines and you are able to view these clusters by the test taker's Parent 1 and Parent 2 sides (or Maternal Side and Paternal Side if identified) or view both sides together. The matches range from 65 to 1300 centiMorgans (cM).

Custom Clusters allows the user to focus clustering around a certain match of interest. Up to four "sidekick" matches that are shared matches with your chosen match of interest. You can also customize the centiMorgan range to reflect your expected relationship level with the matches.

If you have the AncestryDNA Pro Tools, play around with the Custom Match Clusters. It will probably be a few days or a week before how-to videos start appearing to clearly explain and show how to use the tool effectively.

See you at our favorite library!
