Ancestry.com News

So much to report, teach me to take a vacation! Ancestry.com has a new database: Social security applications and claims index, and DNAgedcom has a new tool to report your ancestry DNA total cMs, and I missed mentioning the Ancestry DNA sale at $79 instead of the usual $99 because it ends tonight. Hopefully there will be another one soon.

SocSecAppIndxI tried looking for my uncle in the index and it found him quickly. It listed his birthplace and parents names, useful information.

To learn more about the U.S. Social Security Applications and Claims Index read this post from Randy Seaver: http://www.geneamusings.com/2015/07/new-ancestrycom-database-us-social.html – I recommend following his blog for news about databases added to familysearch and ancestry plus many good genealogy articles.

I hope to review the DNAgedcom ancestry client soon. It requires a subscription which seems fair as increased usage is bound to be costing them money and it is hard for these free sites to exist on donations alone. I like this trend whereby you can subscribe to a site like DNAgedcom or GEDmatch and get extra functionality but there is still plenty of good stuff available for free.

Congratulations to DNAadoption on its anniversary

You do not have to be an adoptee to benefit from a class on DNAadoption.com – they have several one day classes which are introductions, explaining how to use your results, tailored to each specific vendor. They also have a longer basics course and many more advanced courses.

Diane, Tim Janzen, and Kitty at the 2013 Rootstech

The inimitable Diane Harman-Hoog wrote a blog post today announcing the two year anniversary of their classes. Along with Karin Corbeil and Rob Warthen, Diane has taken DNA adoption searches into the electronic age with online courses and much more information available on that site. The many success stories bring tears to my eyes.  A few are here – http://www.dnaadoption.com/index.php?page=reunions and more can be found in the archives of the DNAadoption yahoo group.

I got to meet Diane at the 2013 Rootstech conference along with expert genetic genealogist Tim Janzen and many other wonderful people I had corresponded with via email. Needless to say I keep going back to that conference; of course, the location next to the great genealogy library in Salt Lake City has something to do with that also!

Rob Warthen has written some wonderful tools that benefit all of us genetic genealogists that are hosted over at DNAgedcom.com and are linked to from the DNA adoption site.

Getting all the in common with (ICW) matches at 23andme

The DNAgedcom website has a wonderful feature whereby you can download the overlapping segment data for one of your matches with all your other matches at 23andme. Since it will include you in the CSV file, you can quickly see if you and your share both match another person at the same spot (called triangulation by genetic genealogists).

Here is a sample of that type of match from the resulting sorted spreadsheet for an adopted close DNA relative I am working with (names of non-family removed for privacy):

Comparison Chr Start point End point Genetic distance # SNPs
Adoptee CR vs 1st cousin GP
5 113000000 124000000 11.8 2217
Adoptee CR vs me
5 114000000 121000000 7.2 1401
Adoptee CR vs Dad 5 114000000 124000000 11.2 2038
Adoptee CR vs my brother 5 114000000 124000000 11.7 2112
Adoptee CR vs SS 5 115000000 123000000 8.9 1602
Adoptee CR vs EJ 5 116000000 123000000 6.8 1391
Adoptee CR vs AH 5 116000000 123000000 7.8 1482
Adoptee CR vs AC 5 117000000 124000000 7.4 1421

The four other matches are a bit small but the one with SS is mildly promising; so to be absolutely sure it is a triangulation I have to compare SS back to my family members. Here is how that looks in the 23andme chromosome browser (which can do three at a time with any of your shares):

SSvsUs
And we see that the overlap with me is just a little bit too small to show up, less than the 23andme threshold, but my Dad and brother are a triangulation.

So read on to find out how to use this download feature at DNAgedcom.com.
