News for July 2020
There has been a lot of news in the past few days relating to DNA and genetic genealogy. Linked below you will find news, blogs, and posts from the companies themselves.
MyHeritage Phishing Attempt
Users are reporting multiple phishing attempts, focused on MyHeritage users, which may have been a result of the earlier GedMatch data breach (see below). If true, kit holders from other companies may also see phishing attempts. Be wary, and maintain constant vigilance! [nod to Mad-Eye Moody]
- Security alert: malicious phishing attempt detected, possibly connected to GEDmatch breach – published on the MyHeritage Blog on 21 Jul 2020“We want to alert MyHeritage users about a malicious attempt to steal credentials that we identified several hours ago and is still ongoing.”
- Malicious phishing attempt at MyHeritage – published 21 Jul 2020 by Debbie Kennett, author and founder of the Cruwys/Cruse one-name study.“Following on from the recent security breach at GEDmatch, there has now been a malicious phishing attempt at MyHeritage which is possibly linked to the GEDmatch breach. “
GedMatch Data Breach
GedMatch users began reporting anomalous matches and altered kit security settings on 19 Jul 2020. GedMatch took the site down, restored it, then took it down again. Currently, the site is down, with the following banner: “The gedmatch site is down for maintenance. Currently no ETA for availability” [21 Jul 2020, 10 pm PDT].

Ancestry DNA Changes Matching Algorithm
When Ancestry announced that they were changing their algorithm and removing matches of 6 cM and 7 cM, it seemed like this was the big news for the month. I put it in my July email to the DNA SIG, and we spoke about it at the July DNA SIG Zoom meeting. Clearly, it has been overtaken by events (above); however, it is still of great concern to many genetic genealogists. Please take the time to read these blog posts and decide how you are going to handle your Ancestry account(s). No one quite knows the deadline, either, but it seems to be the “end of July” or the “beginning of August.”

The genetic genealogy field is an emerging technology and a rapidly changing field. The very best way to keep current is through Internet articles and blog posts; traditionally published books simply cannot keep up. Even though this links list is long and daunting, I encourage you to start somewhere – anywhere! – and read as often and as widely as possible. New links are posted often, so please keep coming back. You are welcome here anytime, to select an article and curl up in your favorite armchair or window seat to read and absorb.

Legal Issues and Privacy: Family Tree DNA, January 2019
The tail-end of January 2019 has brought some very big DNA news from Family Tree DNA. Those of you who have DNA tests for yourself or your family members at Family Tree DNA have a vested interest in this topic. If you have tested there, presumably you received the letter from Bennett Greenspan in your email. I strongly recommend that, in addition to reading Mr. Greenspan’s letter, that you read whatever you can find on this topic, and give some serious thought as to how you are going to handle your kits at Family Tree DNA. As always, each consumer must decide for his- or her-self what is best. I have provided some links below to get you started.
First, the article breaking ths story:
- One Of The Biggest At-Home DNA Testing Companies Is Working With The FBI – published by BuzzFeed on 31 Jan 2019.
Next, the press release from Family Tree DNA in response:
- PRESS RELEASE: CONNECTING FAMILIES AND SAVING LIVES published by Family Tree DNA on 1 Feb 2019.
Below are several blog posts on this topic from Judy Russell, The Legal Genealogist:
- Opening the DNA floodgates: FTDNA database now wide open to law enforcement – posted 1 Feb 2019.
- A letter from Bennett Greenspan – posted 3 Feb 2019.
- The logical fallacy: In response to FTDNA – posted 4 Feb 2019.
Leah Larkin, The DNA Geek also felt strongly enough about this to post on it:
- FTDNA Opens the Door to the Cops – posted 31 Jan 2019, updated 3 Feb 2019.
Legal Issues and Privacy: the Golden State Killer and DNA, April 2018
Although still part of “Legal Issues and Privacy,” this topic warrants its own section. Below, please find some posts on how DNA was used to find the alleged Golden State Killer. This news supersedes several of the posts below, in the “Archive” section.
The big DNA news in April 2018 was the arrest of a man suspected to be the “Golden State Killer.” Several jurisdictions have since brought additional charges against this man. Law enforcement used a DNA database we are all familiar with – GEDmatch – to assist them in their search. I have gathered here several blog posts from our most familiar bloggers, discussing this development. Within the posts are more links for additional reading. I strongly encourage you to educate yourself on this topic, which has huge ramifications for the future of genetic genealogy.

Adoption & DNA
These sites are specifically designed for adoptees seeking their roots. Many of the techniques are adaptable to those who are not adoptees themselves, but have an adoptee or a brick wall in their ancestry. (Who among us doesn’t have a brick wall?) Be sure to also see the Success Stories
section below; several of those success stories deal with adoptees and their searches.
- DNAadoption.com – Created by Rob Warthen, DNAadoption.com provides techniques and references for the DNA/Adoption search. Works in conjunction with DNAGedcom.com (listed below under Third-Party Tools) which supplies the tools.
- DNA Adoption, a discussion group – this Yahoo! Group is restricted, which simply means you must request to join with a brief discussion of your reasons for joining.
- Adoption DNA Tools, a discussion group – this Yahoo! Group is also restricted, therefore your membership request must be approved.
- https://www.facebook.com/groups/DNADetectives/ – The DNA Detectives, a Facebook Group for those seeking unknown parents. To participate in this group, you will need to join via your Facebook account.
Vendor Focus
This section was originally created to support our discussion sessions during April, May, and June 2015, when each month was focused on one vendor, and on autosomal DNA only. However, this section has been updated and kept current since then. Below you will find groups of links detailing how each vendor delivers autosomal DNA test results. Please be sure to also review the links above under “Just Beginning” – several offer reviews of each company. Links which are already included elsewhere on this page may not be repeated here.
Family Tree DNA
Family Tree DNA was the first company to offer direct-to-consumer DNA testing, in March 2000. They are also the only company to currently offer Y-DNA and Mitochondrial DNA testing, in addition to Autosomal DNA testing. “Family Finder” is the autosomal DNA test from Family Tree DNA. Because pricing changes over time, and sales are sometimes offered, please check their website for current pricing.
Below are several links detailing how Family Tree DNA delivers autosomal DNA test results (aka Family Finder). These links are listed in chronological order, which is also roughly from basics to more advanced. Be sure to see the recent developments (May 2016) detailed at the end of the list.

AncestryDNA
AncestryDNA began offering direct-to-consumer DNA testing in May 2012. They currently offer an autosomal DNA test. Because pricing changes over time, and sales are sometimes offered, please check their website for current pricing.
Unique to AncestryDNA is that an Ancestry subscription is required to access many, although not all, of the DNA features. See the link below for Ancestry’s description of what is available with and without a subscription. They do offer a special subscription just for DNA customers, called “Insights.” It is not advertised and users must call AncestryDNA to obtain this subscription, for $49/year.
- AncestryDNA with and without an Ancestry Subscription – published by Ancestry.com and last updated 23 Mar 2017.
AncestryDNA has reported a database of more than six million autosomal testers as of November 2017. They had earlier reported the following: five million as of August 2017; four million as of April 2017; and three million as of January 2017.

- AncestryDNA hits the five million milestone – published 8 Aug 2017 by Debbie Kennett, author and founder of the Cruwys/Cruse one-name study.
Below are several links detailing how AncestryDNA delivers DNA test results. AncestryDNA has rolled out several updates and features over recent years. In late 2014, new matching algorithms were deployed behind the scenes; in November 2014, DNA Circles were implemented; in April 2015, New Ancestor Discoveries were introduced; in August 2015, Shared Matches made their appearance; and in November 2015, the Amount of Shared DNA quietly appeared. In May 2016, new matching algorithms were again implemented, and they modified their autosomal DNA chip. Most recently, in March 2017, AncestryDNA introduced Genetic Communities. The links below are listed in rough chronological order, and grouped by topic.

23andMe
23andMe began offering direct-to-consumer DNA testing in November 2007. They currently offer an autosomal DNA test. Because pricing changes over time, and sales are sometimes offered, please check their website for current pricing.
23andMe has reported a database of more than three million autosomal testers as of November 2017.
- 23andMe passes three million milestone – published 8 Nov 2017 by Debbie Kennett, author and founder of the Cruwys/Cruse one-name study.
The 23andMe website has been in a state of transition since November 2015, and is still in transition as of this writing (January 2017). The collected material posted below is in chronological order. Although all the material is applicable, it is not all applicable to everyone. Some customers are on the “old experience,” while others are on the “new experience,” and the tools are different for each.
May 2015 – Below are several links detailing how 23andMe delivers DNA test results. At this time (May 2015), the 23andMe website has been largely unchanged since about mid-2013, so you won’t see a flurry of recent blog postings, but the ones that you do see are still relevant. The most recent change was October 2014, when 23andMe partnered with MyHeritage to host their customers’ family trees. These links are listed in chronological order, which is also roughly from basics to more advanced.

November 2015 – Big changes are coming to 23andMe! 23andMe announced in late October that they will be implementing a “new experience.” On November 12, they made some changes to the existing “experience” in preparation; however, the majority of the changes are still in the future. Existing users will be transitioned to the “new experience” in phases; precise dates have not been announced. It may be as soon as November and December for some; for others, sometime in 2016 is expected. Below are some blog posts and forum posts with such information as is currently available.

- Initial report on the new 23andme for the advanced user – published 23 Nov 2015 by Kitty Cooper.
December 2015 – Big changes have arrived at 23andMe! As some users are transitioning to the “new experience,” it is becoming clear that the changes so far at 23andMe are drastic. So drastic that some prominent bloggers have decided to temporarily suspend their recommendation of 23andMe; see their posts below. Also, be aware that the price (for new kits) has doubled and is now $199 plus shipping. The $199 is a purchase price and there is no additional subscription price.
- Heads Up about the 23andMe Meltdown – published 4 Dec 2015 by Roberta Estes of DNAeXplained.
- Now… and not now: The problems at 23andMe – published 6 Dec 2015 by Judy G. Russell, The Legal Genealogist.
June 2016 – The price for a 23andMe DNA kit remains at $199. They have announced that additional users will be transitioning to the “new experience” soon, perhaps as soon as August 2016. (It is unknown how many users have already been transitioned; also unknown is the timeline for transitioning all remaining users.) 23andMe have also announced a new “in common with” feature that is only available to those on the “new experience.” Collected here are some blog posts detailing what is known so far, and discussing the updates of June 2016.
- New IN COMMON WITH tool at 23andMe – published 26 May 2016 by TL Dixon on his Roots and Recombinant DNA blog.
- A Triangulation Feature on the New 23andme – published 26 May 2016 by Kitty Cooper.

- Get ready for 23andMe change – published 29 May 2016 by Judy G. Russell, The Legal Genealogist.
August 2016 – It appears that a large number of U.S. customers has been transitioned to the “new experience.” International customers remain on the “old experience.” (This still appears to be the case in January 2017.)
September 2016 – 23andMe annouces a new pricing structure, with a $99 “Ancestry Service” and a $199 “Health and Ancestry Service.” This applies to the U.S.; pricing outside the U.S. varies.
October 2016 – 23andMe announces that their “partnership with MyHeritage has come to an end.” Since 23andMe terminated their previous in-house trees in October 2014, when they announced the Partnership with My Heritage, this leaves their customers with no tree functionality at 23andMe.
- Family Tree Update – published 11 Oct 2016 by 23andMe on the Old Experience Forums (users will need to be logged in to read this).
December 2016 – 23andMe announces Ancestry Composition chromosome segment information.
- 23andMe’s New Ancestry Composition (Ethnicity) Chromosome Segments – published 23 Dec 2016 by Roberta Estes at DNAeXplained.

MyHeritage DNA has reported a database of 670,000 autosomal testers as of November 2017.
CeCe Moore has written a blog post presenting her position that MyHeritage DNA is the “fourth pond.” It is well worth a read, and contains several success stories specific to MyHeritage DNA. CeCe has also written a subsequent post about unexpected discrepanices at MyHeritage DNA. Please read both posts, including comments, before making a decision on MyHeritage DNA.

MyHeritage and Geni are also genealogy vendors in their own right. Although you can purchase DNA test from MyHeritage, you can also transfer results from other vendors to your account at MyHeritage. Or, you can incorporate your DNA results into your tree at MyHeritage or Geni. These two genealogy sites are related companies under the same corporate umbrella, but are largely managed independently of each other. In June 2016, both began to offer DNA capabilities along with their previous offerings.

Free although donations are accepted.
- Chromosome Maps Showing Centromeres, Excess IBD Regions and HLA Region – provides a CSV download that works in conjunction with the mapping tool, above, to enhance your chromosome map. Published 9 Jun 2016 by Sue Griffith, the Genealogy Junkie.
Visual Phasing
Visual Phasing is a technique which allows the user to visualize the DNA segments of grandparents when starting with three or more siblings. It is also known as “mapping the crossover points.” Developers of this technique are Kathy Johnston, Randy Whited, and Blaine Bettinger. These posts are all from Blaine Bettinger, and he references the earlier work by the other authors. Please note that if you sign up for Blaine’s email newsletter, you can download a free PDF e-book, “Guide to Visual Phasing,” which publishes these five blog posts in a single location.

Online One World Trees
An online pedigree, or tree, is a crucial tool for any genetic genealogist. It is important to have something to share with your matches, to assist you both in finding your most recent common ancestor. There are many approaches to this, and any genetic genealogist has a plethora of choices for online pedigree trees to share with matches. Below is a selection of articles dealing specifically with One World trees.

X-DNA Advanced
Despite what you might think, X-DNA is not the opposite of Y-DNA. (In fact, mitochondrial DNA has a very similar, but opposite, inheritance pattern to Y-DNA.) But X-DNA has a very unique inheritance pattern, and it stands alone. It is not a separate test – it is usually tested along with Autosomal DNA.
