National DNA Day Sales 2017

National DNA Day is coming soon—25 April. Sales on DNA kits have already started!

Updates added 21 April 2017.

Family Tree DNA (FTDNA) starts their sale on April 20, ending at 11:59 p.m. Central Time on Thursday, 27 April.

Upgrades on prior Y-DNA and mtDNA tests are not included. Adding a new test to an existing kit will receive the discounted sale price. See all of the current sale prices on this product page once the sale starts. To add a test to an existing kit, login to the account first. To order a new kit for someone without an account, just click on the price button on the product page and follow the instructions on the screen.

If you are attending the New England Regional Genealogical Consortium conference at MassMutual Center in Springfield, Massachusetts on 26-29 April, the FTDNA crew will be in attendance. Kits can be purchased at special event prices at the conference until the Exhibit Hall closes on Saturday. The Exhibit Hall will be open to the public at no charge 9:00 a.m. to 5:00 p.m. local time on Thursday; 9:00 a.m. to 5:00 p.m. on Friday; 9:00 a.m. to 4:00 p.m. on Saturday.

AncestryDNA is offering 20% off—sale price is $79 for the autosomal DNA test. Be aware that if you do not pay a subscripton fee to Ancestry you do not have access to all features (see https://support.ancestry.com/s/article/ka215000000TzydAAC/Accounts-after-Cancellation). When viewed on 21 April 2017, this page indicates that with a guest account you can see ethnicity estimates, DNA matches, Genetic Communities, automatic updates to your ethnicity estimate as updates are released, shared matches, and you can contact matches; you do not have access to New Ancestry Discoveries, DNA Circles, Shared Ancestor Hints, viewing your matches’ trees, or lists of surnames and birth locations that appear both your tree and your matches’ trees.

MyHeritage is offering autosomal DNA tests for $79.

LivingDNA is offering $40 off their test for a sale price of $119. LivingDNA's test is different than what we have been using for DNA and there is no match list (so far). See Roberta Estes' blog post describing her LivingDNA test results for more info.

23andMe has no special listed on their website as of 21 April 2017, 4:30 p.m. CDT.

Have fun analyzing the shared DNA segments and determining how you are related to all of your DNA matches!

If you need to learn more about how to analyze your DNA matches check out our genetic genealogy workbook Genetic Genealogy in Practice, co-written by me and Blaine T. Bettinger.

AncestryDNA Genetic Communities

Note: All images are screenshots captured by Debbie Parker Wayne. Where names of living people are include, permission was obtained.

Be aware: Genetic Communities is clearly marked as a "beta" resource. It will change over time and changes have already been seen in the community makeup, names, and assignments since the rollout.

This week AncestryDNA unveiled a new tool for DNA test-takers—Genetic Communities. This tool may clear up some of the widespread misunderstanding of admixture prediction. Admixture predictions are based on where our ancestors may have been thousands of years ago—a period for which few genealogists have documentary evidence. Genetic communities are where our ancestors were within two hundred years (more or less)—a period for which most genealogists have documentary evidence.

Quick! Take advantage of the chance to learn about Genetic Communities for free through until 6 April 2017 by viewing this informative webinar recording. There is a fee to view after that date.

On March 20th on Facebook Blaine asked each of us to predict what our Genetic Communities (GC) would be. My prediction was Upper South and Lower South:

This prediction is based on the birth states of my ancestors shown in the chart below. A Facebook friend started a meme a year or so ago. He had us creating four to six generation pedigree charts listing only the birthplaces of ancestors and color-coding the blocks. Here is the chart I posted last year (I have filled in a few of the question marks since then with ancestor names). It shows all of my ancestors born in the South back to the early 1800s. Earlier generations are not shown here, but they are in the southern United States as far back as I have traced each line. I have one lone fourth-great-grandfather who was supposedly born in New York in about 1800 and was in Mississippi by 1810 to 1820.

My GCs are exactly what I predicted. The names assigned by Ancestry are not Upper South and Lower South. The expected Southern states are included in the GCs which have been given more descriptive names by AncestryDNA.

So how do these GCs help me with my genealogical research? For me, I get few new clues as to locations of ancestors after the late 1700s. Someone with a less extensive tree may get clues as to which states their ancestors came from.

Clicking the Connections button, I do get some clues as to potential European origins of most settlers in the areas where my ancestors settled in the New World. These clues agree with the family stories that have been passed down of ancestral origins in Germany, England, Scotland, and Ireland.

I see a list of surnames that are found more often in this GC than outside of it. I can use the "View All Matches" button to see which of my DNA matches are also part of this GC.

This match list contains only DNA matches who are also part of this GC. A match with a shallow tree may be able to get some clues from the ancestors in my tree that are in this GC.

Back on the window with the GC Stories, if I click on one Year Span in the community story bar I can see which of my ancestors were in this community during that time span. I can use the left and right arrow keys next to the year span to cycle through all year spans.

I can zoom the map in to see finer detail. I can click on a "pin" on the map to see which ancestors are associated with this pin.

As of now, all of my ancestor pins only narrow the locale down to a region of a state. This may be because my tree on Ancestry does not include county level details for all events. However, if Ancestry plans to extend this GC tool to show us our ancestors and ancestors of our matches in the same or nearby counties, I may be tempted to share more of the details in my tree on Ancestry. (I never had a tree on Ancestry.com until I took a DNA test with them and wanted to use some of the DNA tools that require a public tree. I only took the time to enter a barebones tree with ancestors; no collaterals; basic birth, marriage, death info; and states only for some locations. At least once RootsMagic can sync with Ancestry it will be easier to update an Ancestry tree if I decide to place all of my data online.)

It is helpful to see which of my ancestral lines were in the same or nearby counties at the same time. This is a great by-product of the GC maps. Before now, I had to use other tools to map where my ancestors were at any given time.
