Ask the Power Et Al DNA Project Administrators Questions About the Project
PowerEt Al DNA and History Project Frequently
How is the Power Et Al DNA and
History Project going
to protect my privacy?
Ans. Your name will never be shown on the webpage. Your
numbers, your FamilyTreeDNA kit number, your Ysearch.org number, and a
new membership number for our group will be shown but no living person's
name will be listed without
If I find a matching DNA marker
string on the webpage, how do I
contact this DNA participant?
Ans. Send us an email that includes your
intentions and the participants identifying number. We will forward YOUR email address to the
participant. This participant then has an
option of replying to your request, or ignoring your email.
Ideally, everyone will reply, but it is possible that the participant
may want to maintain confidentiality. In other words, you and other
participants like you will actually be the ones to make the final
decision about sharing further information with each other.
I have relatives who may want to take part in this
project, what should I do?
Ans. Send your name and the relative's name
(and email address if possible) to the coordinator's email address. We
will take it from there. However, remember that the potential
participant must be a living male Power/Powers/Poor/de la Poer/Powys
Is there more information about DNA on the Internet?
Ans. Yes, a very large amount. You might go to the
search engine "Google" to find these websites. Use "Genealogy +
DNA" as the search criteria.
Why is it that you insist on male members of the Power
et al clans?
Ans. It is necessary to test the Y-DNA
chromosome that gets passed virtually unchanged from father to son.
This chromosome allows us to track a paternal lineage by comparing the
data markers between several males. If a female cousin wishes to
participate, it is helpful to find a male relate to "sample."
Do the tested Y-DNA markers contain personal information related
to a person's health or inheritance of disease-related genes?
Ans. No, they do not really do anything except
pass from one male to the next. In other words, they do not identify
hair color, IQ, health related issues, intellectual ability, etc. The
very small sample of markers (loci) reported in the Y chromosome DNA
analysis represents a tiny part of the complete DNA "fingerprint,"
therefore, no one could identify you specifically from the Y chromosome
sample even if they wanted to.
If my DNA participant family tree has an error or
omission regarding my ancestors' names, dates, or migration pattern, can
it be corrected?
Ans. We know that there may be some errors in
reporting these generations, so your help will be appreciated. If you
send an email to one of the co-ordinators with the proposed changes
please try to give a primary source for the proposed change.
If participants from the same genealogical lineage have
entirely different DNA marker patterns, what could be the cause?
Ans. It could be that a Power et al ancestor
adopted a boy from outside the clan. Other causes would involve
"non-paternity issues" (infidelity, step-children, etc.) And lastly, the
subject participants may not actually belong in the same line because of
errors in family traditions or family records.
Your participant pages show space for
more than 67 markers or
Ans. A 25/25 match gives you a 50% probability
of having a most common recent ancestor (MCRA) within 7 generations
(some say 3.5 generations). The additional markers (loci) would narrow
