Facts & Genes from Family Tree DNA
May 6, 2004 Volume 3, Issue 3

Welcome to this issue of Facts & Genes, the only publication devoted to
Genetic Genealogy. Facts & Genes is published every month, and provides a
variety of information about utilizing Genetic Genealogy testing for your
family history research, and keeps you informed about the latest
advancements in the field.

Regardless of your background, everyone can learn about Genetic Genealogy
and be able to use this new tool. A science background is not required.

If you are thinking about starting a Surname Project, the new enhancements
announced by Family Tree DNA this month have made the process even easier!
These enhancements, combined with our suite of Project Management Tools,
plus our telephone and email consultation and support, enables anyone with
experience with family history research to start a Surname Project. We
supply the tools and guidance so your Surname Project is successful.
There are just two steps to take to become a Group Administrator of a
Surname Project:

1. Find out if a Surname Project exists for your surname. Click on the
link below to search our database of Surname Projects:


2. If a Surname Project hasn't been established for your surname, then

In the News: Family Tree DNA Announcements

Family Tree DNA is pleased to announce several significant enhancements
were implemented at our web site and several milestones have been
achieved. The enhancements range from the Web Builder Tool for Group
Administrators, to new Ysearch templates.

The following milestones have been achieved:

Ysearch now has close to 4000 entries in the few months since this public
service database was announced.

Family Tree DNA now has over 20,000 records in our database of Y DNA
results. We also have over 900 Surname Projects which include over 8,000

Group Administrator Tool: Generate
The selection Generate appears on the Group Administrator Page. This
report shows all the Y DNA test results for the participants in your
group. These results are sorted, so that results that are close to each
other appear together.

This report has been enhanced to include the Haplogroup for each
participant. There are three possible results that can appear in the
column for the Haplogroup.

If the Haplogroup for a participant has been confirmed by a Haplogroup
test, the Haplogroup will appear and is green.

If the Haplogroup is predicted, and a test has not been performed for the
participant, the Haplogroup will appear on the report in red, if the
prediction is unambiguous. An unambiguous Haplogroup prediction is one
where: the Y DNA matches in the Haplogroup database are either an exact
match or 11/12 match and only one Haplogroup is predicted by the database
for both all 12/12 matches and all 11/12 matches.

For example, if the Haplogroup database has an exact match for the Y DNA
Markers, and this match predicts Haplogroup R1b, and also has an 11/12
match in the Haplogroup database, that shows Haplogroup R1b, then this
result is unambiguous, so the Haplogroup will appear on the Generate
report in red.

If the Haplogroup predicted for a test result is ambiguous, a dash will
appear in the Haplogroup column. If all the 12/12 and the 11/12 matches
in the Haplogroup database do not show the same Haplogroup, then the
prediction is ambiguous so the Generate report will be a dash.

This Haplogroup prediction formula used on the Generate report is more
stringent that the Haplogroup prediction shown for a participant who
clicks Haplogroup on their Personal Page. When an individual clicks
Haplogroup on their personal pages, the Haplogroup page shows all the
matches in the Haplogroup database at 12/12, 11/12, 10/12, and 9/12, and
predicts their Haplogroup. If the participant has 8 12/12 matches for
Haplogroup N, and 21 11/12 matches for Haplogroup N, plus 1 11/12 match
for Haplogroup O, the Haplogroup page will predict Haplogroup N. In this
case, the Generate report will have a "-" in the Haplogroup column,
because the Haplogroup prediction is ambiguous. (Highly likely Haplogroup
'N', but potentially 'O')

For a Haplogroup prediction to be unambiguous, all the exact matches,
12/12, and the 11/12 matches must all have the same Haplogroup.

Where the Haplogroup prediction is ambiguous, the participant can order a
Haplogroup test to confirm their Haplogroup. Where a Haplogroup
prediction is unambiguous, a Haplogroup test is not necessary.

Case Studies in Genetic Genealogy

In each issue of the Newsletter, we look at what Genetic Genealogy will do
for your Family History research. This article is a continuation of the
topic, with situations, called "Case Studies", followed by a
recommendation. The objective of the case studies is to present different
situations you may encounter in your family history research, and how DNA
testing can be applied.

Case Study
From my research, I have two females in the 1870's in the same geographic
area that I think are related, though I have not found any records.
Today, following their lines forward, the last female in one line has a
living son, and the other female line has living females. Is there a test
that will tell me if the two females in 1870 are related?

For your situation, you would want to use the mtDNAPlus test. You would
test the living male from the first Line, since he inherited his mother's
mtDNA, which represents the mtDNA back to one female in 1870. The son
will not pass on this mtDNA, because only females pass on mtDNA. For the
other line, you would test one of the living females.

Spot Light Slagle Surname Project

The Slagle Surname Project was established to determine the common
ancestors of the Slagle families who were in the US by, or prior to, the
Revolutionary War. The Y DNA 25 Marker test is the minimum test preferred
by this Surname Project, and some participants have selected the 37 Marker
test. The Surname Project includes the variants Slaggle, Slagel, Slagley,
Schlegel and Schloegel.

The Slagle Surname Project created a web site with the Family Tree DNA Web
Builder Tool. According to the Group Administrator, it took less than 30
minutes to create their web site.

The Surname Project has 13 participants, and two Lines have been
identified, and possibly a 3rd Line. Additional participants are needed
from the third family before a conclusion can be formed.

Within each group of matches, the matches are 25/25, except one 24/25

The Slagle Surname Project has taken a focused approach, and has achieved
results early in the project.
