Re: Ancestry DNA #dna

Thanks to Charles for such a helpful post.
I agree with what he has written but would like to add some help I get from

I use a programme called Double Match Triangulation (DMT) which I really
find helps me a lot to separate maternal and paternal matches. You make a
Chromosome Browser Result csv file >from FTDNA and you match this against
the CBR file of someone you are matched with. These are files a and b and
will bring up matches as c. Your match will need to send you the file. Some
are very cooperative and others are not. One needs to explain they are not
sending any DNA data in the file only matches.

The way it works is if a matches b and they both match c and each other that
is a DMT. In order to find matches to my paternal grandmother on my father's
side I needed to get cousins to test who have this grandmother as their
maternal grandmother. I have managed to get 2 to test and using the results
of their MtDNA matches and the Autosomal compared with my autosomal and the
results of triangulation I get a good idea of which side the autosomal match
is from.

You can also upload raw data >from Ancestry or FTDNa or My heritage to which gives another pool to search. You can pay 10dollars for a
month to use their Tier 1 utilities . You need only pay for the one month
and then whenever you need it you can take another month. They also have a
Triangulation tool but this is single match and not as useful as DMT. They
do have very useful tools but of course the pool of users is much smaller
than FTDNA or Ancestry.

The autosomal DNA test, be it with Ancestry, FTDNA, 23andMe or myHeritage,
is a great tool for genealogists to advance their research. Each company
will have their pros and cons. You can review them in the ISOGG Wiki website
(Autosomal DNA testing comparison chart).
But one must understand that without a solid and well researched family tree
the chances of a breakthrough are very slim, though there are exceptions to
the rule. The test will not return a magic list of matches that will close
gaps on one's family tree. One should expect to do hard work if s/he is
serious about using atDNA test to help the research. Sit back and wait for a
miracle match will not work on 99.9% of the cases.
