A Segment-ology TIDBIT
AncestryDNA’s new ThruLines automatically finds Common Ancestor(s) – out to 5xGreat grandparents.
AND, because AncestryDNA can also see the Private Trees, it can find Common Ancestors you cannot see – it’s like ThruLines has X-ray vision! If your Match’s Private Tree is searchable, it will even show you the path to the Common Ancestor (otherwise it will show Private for each generation back to the Common Ancestor). This is a very powerful feature. Many of us complain about all the Private Trees.
Well… now ThruLines looks right into them for us and determines our Common Ancestor(s). ThruLines works to find these Private Matches even when they have small Trees, but have an Ancestor who is also in your Tree as a descendant of one of your Ancestors (see previous post about adding children and grandchildren). If you think you know how a Private Match might be related to you (say, by finding several Shared Matches, all on one of your lines), try adding some more descendants in that part of your Tree and wait a day or two. This also helps in developing larger groups of Shared Matches and identifying more Matches in Clusters.
Use ThruLines to find Common Ancestors with Matches who have Private Trees!
