In Part 5 of my ThruLinestm analysis, I’m looking closely at matches with my 2nd great-grandfather, Samuel Vaden Scott.
I was surprised that ThruLines only had one match as a descendant of Samuel Vaden Scott. Samuel had nine children, four with Amanda Jane Haley and five with Lavina Allmend. So, I would have thought there might be more matches. Anyway, Samuel and Amanda had four girls, Clara, Clora, Florence, and Laura. Clora was my great-grandmother and Clara was my match’s great-grandmother, making us 3rd cousins.
DNA Painter’s Shared cM Project 3.0tool v4 indicates that 3rd cousins should share between 0 and 217cM of DNA with an average being 74cM. The ThruLines match (I’ll call RC) and I share 63cM over 4 segments. So, the proposed relationship fits the amount of DNA shared.
My records for Samuel match RC’s records in birth, marriage, and death.
My records for Clora’s sister Clara included the same birth and marriage data. Although I did not have a death record for Clara, I feel confident that the relationship is correct.
According to RC, Clara had eight children. In my records, I had the names of four of Clara’s children and my four were in agreement with R.C.’s. Then, I noticed that two of Clara’s eight children were born before Clara. R.C. doesn’t maintain her test or tree, so I messaged R.C.’s test manager and tree owner about the error. I also asked R.C.’s test manager about possible photos or other documents regarding Clara, her siblings, her parents or other ancestors that he or R.C. might have that are not online.
If you are a descendant of Samuel Vaden Scott (1863-1931), please consider testing with Ancestry DNA; it is an excellent genealogical resource and can help you broaden your tree too. I’d love to learn how we are related.
One of the kits I manage, I’ll call “JS,” has received his Ethnicity Estimate and he now knows he is 88% descended from England, Wales, and Northwestern Europe, 10% from Ireland and Scotland, and two percent from Germanic Europe. Pretty cool.
Ancestry also provides some pretty maps indicating a person’s ethnicity. In his case, the three ethnicity areas overlap.
Ancestry also provides connections to “Additional Communities.” In his case, there are:
“Lower Midwest & Virginia Settlers,” which includes Illinois, Indiana, and Tennessee.
Six of his eight great-grandparents are from the area identified by Ancestry which is as expected. However, the Mississippi & Louisiana settlers is somewhat of a surprise, and not seeing northern Midwestern ancestors was also unexpected. But although the Ethnicity Estimates and Communities are fun and interesting to see, there has to be more. For $99 (regular price) there has to be more, and there is. DNA Matches is the next big part of the process and in my next blog, I’ll describe what to do with them.
[i] Ancestors with two states listed were born in the first state and died in the second state listed.
[ii] The ancestors born in Tennessee also died in Tennessee.
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:
Confirm the shared DNA amount matches expectations for the relationship.
Confirm the cousin’s descendants from the common ancestor and a known child of the common ancestor.
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.
In all cases, the DNA amount matched matches expectations as suggested in DNAPainter.
In all cases, the individuals are descended from individuals that I had independently identified as children of Asa.
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.
17 new cousins descended from Rosa Della Roberts.
2 New cousins descended from Charles W. Roberts.
10 New half-cousins descended from Sarah A. Roberts.
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.
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.
Twenty-Two of our chromosomes are recombinant in nature, which means you receive 50% of your mother’s DNA and 50% of your father’s DNA. The 23rd chromosome, the X-Y or X-X, is quite different. If you are a male, you received a “Y” chromosome from your father and you received an “X” chromosome from your mother. That X is a recombinant, in that it consists of 50% of your mother’s DNA. However, if you are a female, you received 50% from your mother as recombinant from her, but you also received your other X chromosome as a duplicate from your father. The effect of that is that the amount of DNA received from an ancestor through your X chromosome is higher if the ancestor path switches gender every generation. For example, my mother received 50% from her mother and 50% from her father. Her father received 100% of his X DNA from his mother (recombinant).
Blaine Bettinger (The Genetic Genealogist) has an excellent article, “More X-Chromosome Charts,” which provides charts showing both the Ahnentafel numbers and the percentage of X-DNA you received from which ancestors. The effect of this switching back and forth is that a male receives 12.5% of his mother’s father’s mother’s father’s mother’s father’s mother instead of the 0.78% that he received from that ancestor (a 5th great-grandmother) in the other 22 chromosomes.
I call that line a “zig-zag” line because it shifts gender every generation can provide insight into genetic connections that can really help in understanding matches and where you and that person may have a common ancestor.
In any generation you follow a woman’s mother, the expected % of X-DNA is cut in half. So my mother received 50% of her X-DNA from her mother. I have 50% of my X-DNA from my mother’s mother, so a similar “zig-zag” chart for my mother would be:
Because my great-grandfather, John Montran’s life is such a mystery and because his parents are a complete mystery to me, discovering ancestors with whom I share X-DNA with may provide key insight into potential candidates for John.
If you share any of the above ancestors with me, I’d love to hear from you and try compare our matches in order to learn of our common ancestor.
DNA Testing and Results Companies
23 and Me requires you to compare DNA in their browser and then manually determine if there is a match on the X-Chromosome. You can download your raw DNA data and import it into several other services. (Kits available for $69 until 23 Nov 2018)
AncestryDNA doesn’t provide information about X-DNA Matches nor does it provide for a chromosome browser. You can, however, download your raw DNA data and import it into FamilyTree DNA and GEDMatch. (Kits are available for $59 until 21 Nov 2018)
FamilyTree DNA shows you that an individual has an X-Match with you, even if that match is extremely low, even down to 1cM if they match otherwise at higher levels. You can test with FamilyTree DNA, with “Family Finder.” Alternately, you can also upload raw DNA results from Ancestry, 23andMe, MyHeritage and the National Genographic Project 2.0. (Kits are $79.00)
GEDMatch allows you to select whether a match is based on autosomal or X. By selecting X, you can see only those matches with whom you share X-DNA. If you look at the individual’s kit number and it begins with “A” they kit was imported from Ancestry. GEDMatch does no testing but allows you to upload your raw DNA data from various services including Ancestry, FTDNA, WeGene, MyHeritage and others. GEDMatch does no testing,
MyHeritageDNA does not show you your X-Matches (at least not with uploaded kit results).
LivingDNA does not show you any match data.
Looking solely at X-Chromosome match capability, FamilyTree DNA and GEDMatch are the best, with 23 and Me following closely behind. AncestryDNA, Living DNA, and MyHeritageDNA do not support X-Chromosome match analysis. Look closely at your tree and your X-Chromosome, you may find that a new clue to help find that elusive ancestor.
