I am incredibly honored to announce my election to the Board of Trustees of the New York Genealogical & Biographical Society! The NYG&B is the largest and oldest genealogical society in New York State, and the second oldest genealogical society in the nation. As a lifelong genealogist with New York roots dating back almost 250 years, joining the NYG&B is a dream come true for me.
Over the past decade, DNA has become a powerful tool for genealogical research. As a member of the NYG&B’s Board of Trustees, I hope to be able to help bridge the (ever-closing) gap between traditional genealogy and genetic genealogy, and help both members and non-members understand and incorporate DNA into their family histories.
The board represents an incredible group of people dedicated to helping people discovery their family histories, and I am so grateful to be able to join them. The full list is below.
Yesterday, when I checked my AncestryDNA account I had 205 pages of matches, or 10,250 matches in the database. Today, thanks to Ancestry’s new matching algorithm, I have 57 pages of matches, or 2,850 matches in the database (a reduction of 72.2%!). I also have DNA Circles, groups of people who MIGHT share a common ancestor (some of whom share DNA with me).
If you’re serious about genetic genealogy, you’ve heard of GEDmatch. The third-party site is one of the few ways to compare testing results among the three testing companies. The site
However, since GEDmatch is run by two incredible volunteers (Curtis Rogers and John Olson) with full-time jobs, the site has experienced server issues and downtime. Many have lamented that there was no monetization plan in place, but gave donations in hope that it would help the site grow.
This week, GEDmatch announced a monetization strategy, namely advanced tools that are only available to Tier 1 members at a nominal cost of $10/month:
Basic GEDmatch programs remain free and we plan to keep them this way. Donations help cover the costs associated with running this site, and will provide you with the benefit of using the additional Tier 1 tools for a period of time equal to one month for every $10 donated. You may use the ‘Donate’ button below, for a one-time donation of any amount, or the ‘Join GEDmatch’ button to establish a recurring $10 per month amount.
At the Family Tree DNA 10th Annual International Conference, FTDNA announced that they were reducing the price of autosomal DNA transfers (from the AncestryDNA test or the V3 test from 23andMe) from $69 to $39. Additionally, you could upload your raw data for free and you would receive information about your 20 closest matches in the database. On top of that, if you convinced 4 others to transfer their raw data, you would receive a transfer for free!
Once you’ve uploaded, you’ll receive an email with a login and password. You’ll then receive a second email a short time later, after your results have been processed. In the meantime, you’ll see this:
Short Summary: Before the end of the year, AncestryDNA plans to update our match lists using a new algorithm that reduces the number of false positive matches. For the first time, matching DNA segments will be characterized as IBS (i.e., a false positive) based on something other than simply segment length.
Last Monday, October 6th, I and six other members of the genetic genealogy community attended a ‘Bloggers Day’ hosted by AncestryDNA at the San Francisco headquarters of Ancestry.com. Two other members of the group have already written about the event:
While at ‘Bloggers Day’ we discussed many issues including the Y-DNA and mtDNA databases originally scheduled for destruction, upcoming changes to AncestryDNA’s matching algorithm (much more below), and other upcoming changes to the AncestryDNA about which you will hopefully soon hear much more.
In 2008, I wrote about the case of Mr. and Mrs. George Fry, who are believed to have brought a particularly negative mutation with them to the New World from Europe in 1630 (“A Single Colon Cancer Gene Traced to 1630 – The Future of Genetic Genealogy?“). The mutation – in the APC gene – increases the likelihood of colon cancer, and has been found in many of the Fry’s living descendants.
In this months’s issue of Nature Genetics (see “Mutations in SGOL1 cause a novel cohesinopathy affecting heart and gut rhythm“), researchers using the BALSAC Population Database traced a founder mutation in SGOL1, which causes Chronic Atrial and Intestinal Dysrhythmia, termed CAID syndrome. So not only is it interesting that the same gene is involved in both heart rhythm and intestinal rhythm, but that the DNA has been mapped to this ancestral couple. The couple, whose names were not provided, were married in France in 1620 and arrived shortly thereafter in Nouvelle France.
A great resource from Jay Chandrakumar at Genetic Genealogy Tools (www.y-str.org) – SNPs extracted from sequenced ancient genomes and loaded into GEDmatch. Try out admixture tools with these GEDmatch profiles, but don’t expect many matches in One-to-Many!

I’ve written before about a poster presented by AncestryDNA at the American Society of Human Genetics 2013 annual meeting, entitled “Reconstruction of Ancestral Human Genomes from Genome-Wide DNA Matches.” In the abstract, the group describes how they use sequencing information from hundreds of descendants of an 18th century couple to recreate portions of the genomes of that couple.
AncestryDNA’s 2014 ASHG Poster
The AncestryDNA group has continued to refine the process of reconstructing the genomes of ancestral couples, and has a poster in this year’s American Society of Human Genetics annual meeting:
Direct-to-consumer DNA testing companies are revealing family secrets, many of which are emotionally damaging, without regard to those affected by the family secrets and without sufficient warning to the test-taker.
Unfortunately, rather than presenting a balanced view of the consequences of uncovering family secrets using DNA testing (and despite the title of the article), Belluz focuses only on examples of negative outcomes. The article is a perfect demonstration of “genetic exceptionalism,” the theory that genetic information is special and must therefore be treated differently from other types of information. Despite its many adherents, genetic exceptionalism is a theory without a logical underpinning.
VIGR will offer courses on a comprehensive list of genealogical subjects, giving genealogists access to a great curriculum year-round through the VIGR virtual platform. I’m proud to announce that I will be a speaker for the VIGR, and I look forward to interacting with the online genealogical community though my course on autosomal DNA. I am honored to be listed among the incredible speakers below.
No fewer than nine upcoming courses are already listed on the VIGR official website, the earliest commencing in November this year. Each will consist of a total of four 90-minute lectures, presented two each on consecutive Saturdays. Each course will also have extensive syllabus material and practical exercises, as well as time for Q&A. The institute intends to keep class sizes small, which allows for more interaction with instructors and a greater depth of instruction as compared to more typical genealogy webinars.
