I didn’t notice this yesterday when I checked their blog, https://blog.familytreedna.com/, but I saw it today even though it’s dated May 10, 2019 – Understanding Your Ancestral Origins – FamilyTree DNA (FTDNA): https://blog.familytreedna.com/understanding-your-ancestral-origins/.
Of all required academic literature in grade school, Sherlock Holmes was my absolute favorite. It combined two of my favorite things: Britain and justice. I found myself in awe at his ability to piece together comically complicated mysteries in such a great way. In real life, even the best detective wouldn’t make it past Chapter 1 without giving up and immediately changing professions.
You know my methods, Watson
Genealogy is detective work. If all of the answers were just given to you, there wouldn’t be any interest or excitement left over. And while a lot of the aspects of your results do reveal absolute truths and answers, many clues are often open to supplemental research and interpretation. For example, if you’ve taken one of our deep ancestral tests (mtDNA, Y-DNA), it should be understood that these tests are really good at tracing your deeper, more distant ancestry. These are not tests to find close relatives or give immediate answers about from which population you descend (or really anything about your more recent genealogy). They focus on DNA that doesn’t change, or mutate, often. As test results are based on these mutations and their rates of mutation, since these DNA types mutate less frequently, they look at much more distant, and broad, ancestry.
There are some misconceptions about these types of results. For example, if you’ve taken an mtDNA or Y-DNA test, you’ll have a section in the results titled, Ancestral Origins. For many, this page consists of a page of countries, with other stats sprinkled in. To be clear, this is not a page that shows your definitive countries of origin. Instead, it is looking at your (mtDNA or Y-DNA) Matches, or people with whom you share distant ancestry. If any of your Matches have included a country of origin, we add it to this list. Therefore, all of the info on the Ancestral Origins page is entirely user-generated. It’s meant to be a rough guide, using information from your Matches to give you more insight.
Here’s a shot of my Y-DNA Ancestral Origins page:
Since it lists countries my matches themselves have have listed, this is a reflection of that. Though it can never guarantee ancestry from a specific country, above is a really strong indication that 1. I have a lot of paternal Eastern European ancestry and 2. I have Jewish (Ashkenazi) ancestry. As the Match Total column represents the number of people I match at a specific level that have listed that country of origin, I want to look for Countries with large Match Totals. The Country Total represents the total number of people in our database that have listed that country of origin, and the Percentage represents the number of people I match that list that country vs. the total amount of people that list that country. The Comments column can show some additional information about that person’s most distant known ancestral location. So, for example, if you just match 1 person from a specific country (Match Total), or you have 1 Comment that says something, that’s not necessarily a very large indicator. However, in my case, you can see that over half of my Comments say Ashkenazi, which is a strong indication of paternal Jewish ancestry.
This page is another tool that can help you piece together the mystery of your ancestry. As the database grows and more people test, tools such as this will become more accurate and specific. We’re all pioneers exploring a whole new avenue of genealogy. The future of uncovering your past is going to be really exciting.
