We all know that it can be frustrating trying to identify who a genetic match is and how they are related to us. Today we’ll look at some of the ways we can learn more about matches using the limited information we are given.
But this post has a two-fold purpose. The first purpose is to help people identify their AncestryDNA matches even if the match has no tree, has a private tree, has a meagre tree, and/or is not communicating. Keep in mind, some people have very good reasons for not having a public tree (they don’t have one, there’s a bad history, and so on), so this post is not at all about chastising people who don’t have a tree.
The second purpose, which is perhaps even more important, is to help test-takers who want privacy understand the ways in which people can use information to identify them. EVERY test-taker has a right to make their information as private as possible; but you must also understand that DNA is inherently identifiable. The purpose of genetic genealogy is identification. The only way to maintain 100% DNA privacy is to not take a DNA test. Period. The next best way to maintain some level of DNA privacy is to make your information as private as possible, as we will see below.
