Centimorgan range guidance

This episode focuses on the exciting custom clustering feature now available in Ancestry's Pro Tools. Diana introduces the tool, explaining how it allows for the strategic targeting of specific ancestral lines, offering more flexibility than the original clustering tool. She describes Ancestry's process, which looks for matches sharing 65 cM to 1,300 cM with the user, and then finds those matches that also share at least 20 cM with each other. Nicole discusses the key benefits of using custom clusters: they help you hone in on specific ancestral lines, quickly identify groups descending from common ancestors, and work more efficiently at distant generations.

Before creating a cluster, Diana reviews critical points from Ancestry, noting that clusters expire after 30 days unless saved to a group and you are limited to 25 clusters in your history. Nicole shares Ancestry's recommended centimorgan ranges based on the generational distance of the ancestor you are researching. She then walks through the four steps for creating a cluster: choosing a target match, selecting four additional "sidekick" matches, setting the centimorgan range, and generating the cluster. Diana provides a real-world example from her Cline family research, detailing how she used a custom cluster with a 20-50 cM range to test a hypothesis about the parentage of John C. Cline. The results successfully separated her matches into distinct sub-clusters that provide additional evidence for her research. Listeners learn practical tips for success, including saving clusters strategically, trying different target and sidekick match combinations, and systematically tracking all experiments in a research log like Airtable. This powerful strategy helps you apply a new approach to breaking down your DNA research brick walls.
