Ancestry’s ThruLines – Part 3 – Asa Ellis Roberts

In previous articles, I’ve considered Ancestry’s new ThruLinestm feature. In Part 1, I looked atThruLinestm in a general manner. In Part 2, I developed a process and decided on some caveats I would use with it.  Here in Part 3, I proof my process/procedure by using it and verify the process holds true in use.  Briefly, the process is:

  1. Confirm the shared DNA amount matches expectations for the relationship.
  2. Confirm the cousin’s descendants from the common ancestor and a known child of the common ancestor.
  3. Analyze the remaining path to the cousin, assuring things make sense.

I used the process focusing on my 2nd great-grandfather’s (Asa Ellis Robert) descendants.

All of the descendants of Asa are 3rd cousins. Asa was married twice, so descendants of Asa and Patience Anna Marshall should be 3rd cousins. Descendants of Asa and Cynthia Minerva Toney would be half third cousins to me. DNA Painter’s Shared cM Project 3.0 tool v4 indicates that a 3rd cousin should share between 0 and 217 cM of DNA and half 3rd cousins should share between 0 and 178 cM of DNA.

ThruLinestm indicates I have 18 Cousins that have tested with AncestryDNA.

  1. In all cases, the DNA amount matched matches expectations as suggested in DNAPainter.
  2. In all cases, the individuals are descended from individuals that I had independently identified as children of Asa.
  3. In all cases, the individuals have a pedigree chart that makes sense.

Thanks to ThruLinestm I added 37 new cousins to my chart all descended from Asa Ellis Roberts.

  1. 17 new cousins descended from Rosa Della Roberts.
  2. 2 New cousins descended from Charles W. Roberts.
  3. 10 New half-cousins descended from Sarah A. Roberts.
  4. 8 New half-cousins descended from William T. Roberts.

The process is much faster than any methods I ever used before to verify a person’s relationship to my tree. I’m happy with the process and feel confident that I’m adding valuable information to my tree to better the likelihood of connecting ancestors. ThruLinestm is great for widening your tree to include individuals that are descendants of a known family unit.

If you are a descendant of Asa Ellis Roberts, consider testing with Ancestry DNA; it is a great genealogical resource and can help you broaden your tree too.

Ancestry’s ThruLines – Part 2

General Genealogy
DNA, Brown Line
By Don Taylor

I was recently asked what I thought about Ancestry’s new ThruLinestm feature, how much did I use it and what do I accept from it. In using autosomal DNA results, it is always good to have a very wide tree. The wider your tree is, the more cousins you have identified, the more likely you will be able to determine the relationship between you and a DNA match.

So, I decided to look at the matches that reach my great-grandparents, Arthur and Mary (Manning) Brown. They had 12 children, 11 of whom reached adulthood, so I figured there would be many cousins there.

ThruLines for Arthur Durwood Brown (Partial)

I tend to analyze each person left to right, so I started with a 2nd cousin, descended from Victoria Brown.

ThruLines – Victoria Brown Segment
  1. Look at the centimorgan (cM) match amount. In this first case, the individual and I share 134 cM across nine segments. Our trees suggest we are 2nd The Shared cM Project 3.0 tool v4 at DNAPainter.com https://dnapainter.com/tools/sharedcmv4 indicates that 2nd cousins should share between 46 and 515 cm of genetic material. So, our match is within the expected range.
  2. Does the other person’s tree match yours? In this case, we have all of the same data for her grandmother. In order to accept a ThruLinestm display, both 1 and 2 must pass.
  3. Do the other descendant entries make sense? In this case, the cousin’s father is still living (and thus redacted). I had the same person with no discrepancies in data. Therefore, I am sure of the match. I did contact the individual to learn of her first name and then entered her into my tree in the right place.
ThruLines – Edward Brown Segment

The next cousin to analyze is a descendant of Edward Lewis Brown. This cousin and I share 144 cM over seven segments, well within the expected range for 2nd cousins, once removed.

According to ThruLines, this match a great-granddaughter of Edward through her mother and her grandmother both of which have private entries.  My records indicate that Edward had ten children, seven of whom were girls. I also don’t have information on any of the granddaughters of Edward. As such, I can’t place this individual on the tree at all. I then contacted the cousin and asked her about her connection to Edward Brown. Her mother and her grandmother’s name if possible.  Once I receive that information, if her grandmother matches one of my known children of Edward Brown, I will accept her and her mother’s names from her tree.

ThruLines Arthur Brown Segment

Cousin number 3 was somewhat expected. The amount of DNA, 98 cM, fit expectations for 2nd cousins once removed. I had identical information for her grandfather and her great grandfather. Looking at my data, I had four potential women (all living) who could be the mother of this cousin. I contacted her and asked which of the sisters was her mother. She replied, and I placed her onto my tree.

I followed a similar process for all of the other cousins that ThruLinestm provided connections to.

As you can see, my process it to:

  1. Confirm the shared DNA amount matches expectations for the relationship.
  2. Confirm the cousin’s descendants from the common ancestor and a known child of the common ancestor.
  3. Analyze the remaining path to the cousin, assuring things make sense.

Then, I accept the individual’s tree as “tentative” from the grandchild of the common ancestor to the cousin.

I like ThruLinestm, but only for widening my tree to include individuals that are descendants of a known family unit.


Note: I do not even consider anything in the individual’s tree before our common ancestor.

Ancestry’s ThruLines

By Don Taylor

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.

Clicking on the 2 down block opens up the names of two individuals from Beth’s tree.

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.
