“This website is particularly important for Ancestry.com customers since Ancestry.com does not reveal the matching half-identical region (HIR) data to customers who test there. It is thus imperative for Ancestry.com customers to transfer their data to GEDmatch so that they can see which HIRs they share in common with other Ancestry.com customers.” from Tim Janzen MD, RootsTech 2018 handout
