I am very grateful for the marvelous response by NEHGS members
to the November survey on their experiences with genetic genealogy -- their
responses were detailed and thoughtful and were accompanied by some excellent
recommendations now under careful consideration. We regret that we could not
answer all the questions, but we tried to reply to each respondent. Because many
of the responses were from family project administrators, we had the added
benefit of learning the experiences of over 1,000 genealogists who are using DNA
data in various ways to augment traditional methods of
genealogy.
Positive and Negative Experiences
I am
pleased to report that at least half of respondents were very satisfied or just
satisfied with using DNA analyses, while most of the rest report "mixed"
results. Many of the problems involved either uncertainty about embarking on
this new approach to genealogy or the need of expert assistance in interpreting
the results. Fortunately for some projects, their selected administrators have
attempted to keep up with the emerging technology and are very conscientious
about assisting project members, helping them to understand both the
possibilities and the limitations of Y-chromosome and mitochondrial DNA studies.
Comments varied all the way from "Have been able to identify family
groups," to "Totally unsatisfactory" and "Don't do DNA testing for genealogy --
it is not beneficial -- stick with the documentation and
records."
Markers and Charges
The question about
markers proved to be rather complex, but it helped to explain why some
genealogists because frustrated with using DNA. Those who started very early
using the genetic approach might be compared with the person who rushes out to
buy that sleek, newly designed car, only to find the manufacturer didn't foresee
some glitches. After a few recalls, the car is likely to get more curses than
smiles from the frustrated owner.
There seemed to be general agreement
that a 12 marker study was an acceptable way to start (some early studies
employed as few as 4 markers), but only if these were "not common." Most
genealogists seem to prefer 25 markers and many are now using 37. We didn't get
enough comments about haplogroup studies to draw any conclusions, except that
some individuals didn't seem to be aware that studies involving slowly mutating
DNA or mtDNA are useful for distant ancestry or ethnic identification but are
not all that helpful in identifying the family pedigrees usually sought by
genealogists.
The majority of respondents felt the entrance level costs
were reasonable. Extended testing, such as 37 markers, can be very beneficial
but was considered too expensive for some.
Confidentiality and
Accessibility of Data
Only a few genealogists expressed any great
concerns about the confidentiality of their DNA results; some didn't know and a
few didn't care. The majority seemed satisfied with the assurances provided by
the testing laboratories. A few weren't that convinced, however. One reply was,
"I have not done DNA to date because I fear there isn't the legal security for
what happens to the results in the future." Apparently some administrators also
encountered similar apprehensions when recruiting new members for their
projects.
There is no uniformity concerning the accessibility of results,
as this varies markedly from study to study. Some provide completely private
reports for each participant. Summary reports are prepared by other
administrators. One study posts all its results on its website. It also became
apparent that our question concerning the identification of a serious heritable
illness was not clearly stated. The size of family groups continues to expand,
especially when DNA identification supports the traditional genealogical
documentation. Families are rapidly gathering new members and are reaching
proportions not previously encountered. As in ethnic groups, predisposition to
certain heritable physical or mental characteristics, or recognized diseases, is
likely to become apparent. This could pose an ethical, or perhaps legal
challenge for a project administrator, as preservation of confidentiality has
become a very serious concern in the medical world. If a heritable condition
becomes apparent in a family group, are all relatives notified who are
considered potentially at risk? And what about persons wo have just joined or
are planning to join the project?
PERTINENT
COMMENTS
I am very grateful for all the time and thought which went
into the replies to the survey. Some are included here:
“All positive
results for us” (although it took 5 years). “DNA settled problems”
“I’d
be interested in the bad situations encountered by others.”
“Need for
independent, experienced, reliable people to help newbies....” (Suggested
checking posts at Genealogy-DNA and DNA_Newbie@yahoo.com)
“It can’t hurt
for NEHGS to be involved, even....in a limited way to help out those....just
getting interested.”
“DNA enthusiasts have been working hard to educate
‘traditional’ organizations about this tool.”
“Contact ISOGG for possible
speaker on genetic genealogy.”
“Need to understand ‘anthrogenealogy’,
such as the National Genographic Project”
“Request recommendations for
labs doing DNA for genealogical purposes.”
“Set up an alliance with
others, e.g., World Families, for DNA surname projects.”
“Can you
recommend where to get tested?”
“Spent a lot of time trying to prove
something that was incorrect...” Happy to find error via DNA
analysis.
“Very pro using this as a method of breaking through brick
walls.”
“Many participants do not understand DNA at
all....”
“Attended Elderhostel in New Hampshire by DNA experts” (30
persons attended course)
“Would like help to interpret the Y-DNA
results.”
“There is no one to communicate with....”
“Those doing
DNA testing have ‘over sold the capacity and benefits...’”
“$100! I’d
rather spend that on good genealogy-related books.”
“Exciting field but
needs to be better communicated.”
“Yes, I think NEHGS should do
this.....a big part of their job is education -- expand activity into DNA
education, research and counseling.”
“Like to see NEHGS (or some other
credible institution) set a standard or guideline [for] acceptable genealogical
conclusions.”
“Suspect match information is being generated, e.g., on
Ysearch.org, so people feel they are getting something for their
money.”
“I have 35 ‘high resolution’ matches at FTDNA, 62 at Ysearch --
test must be very general.”
“I hold NEHGS in very high regard, but I am
not sure it should try to go out on a limb as a consultant at this time.”
(Suggests working relationship with one or two testing firms.)
“NEHGS
needs to work with experts to develop standards.”
“Prefer NEHGS....
prepare a grant proposal to encourage greater participation in surname testing
and extend number of markers tested.”
“Serious mistakes encountered with
SNP testing of Haplogroups.” Worries about quality of SNP results for National
Geographic Society.
“DNA testing will work very well to assist
traditional genealogy. It’s wonderful.”
An administrator of a
700-subscriber study states, “...there is not much understood about this new
tool” and expresses a “need to educate researchers in an evolutionary process. I
believe we are demonstrating the furthering of family history by integrating DNA
findings...” but also is concerned that use of DNA testing for genealogy is
overstated, as it is actually a supplement to traditional research.
A
genealogist “questions use of quality controls” by DNA
laboratories.
“Should NEHGS provide an interpretation service? It could
be worth investigating -- possibly ‘free’ but with a suggested
donation.”
Respondent needs “help to direct me to someone.... to answer
my question.”
“DNA can be a very useful supplement.”
“DNA will
become an important part of many of our lives, not the least being genealogists.
So yes, I do support NEHGS getting more
involved.”
CONCLUSIONS
Respondents appeared to be
generally satisfied with the performance and service rendered by the larger
laboratories, although some felt that the advertising could be misleading and
perhaps tended to over-emphasize the relative role of DNA studies in genealogy.
This is hard to evaluate, because so many genealogists have been recently
introduced to genealogy via the internet and haven't fully explored the other
possible sources of genealogical information.
I've included some of the
comments received and suggest viewing appropriate websites which carry
information about laboratories serving genealogists, with comments from
clients.
The use of DNA is swiftly establishing its value in genealogy --
not as a replacement for traditional research, but as a useful supplement,
especially for "brick wall" situations and for clarifying diverse pedigrees
which carry the same or similar surnames. Few genealogists are qualified
geneticists, and we are merging an art with a science. The science of genetics
is advancing at break-neck speed, so we are going to have to adapt to new
technology and accept newly recognized "markers" in the foreseeable future,
including somatic markers which are currently classified as "junk DNA." There is
striking similarity with early mariners who had no idea what was over the
horizon when the sun rose each morning and they feared sea serpents might be
lurking beneath the waves ahead.
