One of the many huge announcements made at Roots Tech was Ancestry unveiling of ThruLinestm. Many bloggers have been writing about it, and I thought I’d see what it can do for me and the DNA Kits that I manage on Ancestry.
Immediately upon entering AncestryDNA®, you now see ThruLines as the right-hand block which used to house DNA Circles. There is a link in the block to restore DNA Circles if you wish, but I wanted to Explore ThruLines.
ThruLines then presents a block of my ancestors, parents, grandparents, great-grandparents, etc., all the way to my 5th great-grandparents. (About the limit of what Autosomal DNA results can predict relationship at.)
As I clicked on my parents, ThruLines presented my half siblings for whom I’ve known about for several years now. The same thing was true when I looked at my grandparents’ entries. Looking at my great-grandparents, Hugh and Clora Scott Robert’s ThruLines yielded a 2nd cousin that I’ve corresponded with before.
When I looked at my Great Grandparents, Joel Clinton and Marada Alice (Lister) Barnes, the power of ThruLines came alive. Two new lines showed. It showed my paternal grandmother had two sisters — one a half great-aunt to me the other a great-aunt. I had known about Essie’s sisters, Flora and Mabel, but hadn’t traced their descendants down. ThruLines provided links to a half 2nd cousin 1x removed (Beth) and to another 2nd cousin 1x removed (JK). In both cases, I know about their grandparents (Flora & Mable) but I didn’t have descendants for either Flora or Mable. The first one, “Beth” had a tree that provided names, dates, and relationships. That line should be easy to replicate with sources. The second person, cousin “JK,” had two “Private” individuals between her and my great-aunt Mabel. I should be able to follow Mable’s descendants to that cousin fairly quickly also. However, because ThruLines shows JK’s mother and grandfather are the pathway to her great-grandmother Mable, JK’s line is clear enough to provide information to be able to ask clear and concise questions regarding JK’s ancestors.
Continuing to look at my great-grandfather Arthur Durwood Brown, I found seven DNA cousins with whom I share Art Brown as a common ancestor. Two of the seven were new to me. That is to say, I knew they were DNA cousins before, but I didn’t know exactly how they were related. Thanks to ThruLines, it is clear.
One problem I do see with ThruLines is that it relies entirely upon individual’s trees. That is to say, if someone has a mistake, the mistake takes shape and form throughout the system. As an example, I believe my 2nd great grandfather is William Henry Brown, but many others think that Arthur Durwood Brown’s father was Henry “Mack” Brown. ThruLines won’t show anyone who believes that Henry “Mack” Brown might be the common ancestor because he doesn’t show as an ancestor in my tree. So, if your tree is right, ThruLines will confirm your tree. But if your tree is wrong, then ThruLines will confirm your tree with the wrong trees of someone else. I think it is a dangerous path to follow.
So, it is essential for you to do your own research to validate any “hints” you receive from anyone and ThruLines is no exception to that rule. Consider what ThruLine provides as a hint and you’ll be okay. I like ThruLines much better than I liked DNA Circles. It will be more useful in helping me to quickly develop width to my tree, something that is important in understanding DNA match results.
