Message to Project Members

 

Hi Everyone:

 

You should have received a message from FTDNA about their March sale for Mt-DNA testing. This sale goes through Tuesday April 1st 2014 at 11:59 pm CDT.

 

Testing has advanced over the years I have been administrating this project. I did not initially advocate Mt-DNA tests as women traditionally take on the surname of their husband and it is difficult to get far enough back to trace a woman’s lineage. However, with Full Sequence testing that has changed. See the table below:

 

 

Testing Level

Matching Level

Generations to Common Ancestor

50% Confidence Interval

95% Confidence Interval

mtDNA

HVR1

52 (about 1,300 years)

NA*

mtDNAPlus

HVR1 & HVR2

28 (about 700 years)

NA*

mtFullSequence

HVR1, HVR2, & Coding Region

5 (about 125 years)

22 (about 550 years

 

 

 

 

 

According to the ISOGG Wiki at http://www.isogg.org/wiki/MtDNA_testing_comparison_chart

 

23 and Me tests some “selected branch-defining SNPs” on both HV1 and HV2 but it is not a full sequence test. Likewise Ancestry DNA tests 16000-16569 on HV1 and  1-390 on HV2 which is not a Full Sequence test. Neither company, therefore, does Mt-DNA matching.

 

A number of Bloggers, several of whom are administrators, have commented about this sale. Here are links to some of their blogs you might wish to read.

 

Roberta Estes, in her very informative style, has commented on March 29 or 30 how she incorporated her Family Finder results with one of her matches and her mt-dna results.

I have had a “new” blog site up

 (Your Family Tree at http://yourfamilytree.micbarnette.com)

for quite a while but, due to lack of time, have not been posting to it. Part of my procrastination has been I have four FTDNA projects and I felt some of what I wanted to blog about would be beneficial or pertinent to one or all those projects. So, rather than post to five different sites I was trying to figure out a way to post to only one site. I have decided “now is the time” to go ahead and start posting to that site. I will still post to each individual website if something is only pertinent to that surname. You will be able to access each of my sites by clicking on the Links and RSS tool bar at the top of the page. You will have to go to each individual Blog to subscribe to each individual blog by clicking on the “Subscribe” button on that Blog site.

 The first blog on the new site is a statistical summary of each of the projects I administer: the Barnett, the Finch, the Barney, the Dallas Genealogical Society DNA Projects. It was posted March 30, 2014
