What to expect from your DNA test

My State of understanding is as follows

Initial Reports Received
So, it has been 6 to 8 weeks and I just got my
DNA results back. The challenge will be to
understand what it means. Here are the two
tests that I took…

1. The YDNA test. 37 markers.
(for males only. Traces the family tree back
from father to son over the centuries.)
Results: Looks like I am in the R M269 Haplogroup.
In the family tree of man, that is the branch I am on.
I can look online at my chart and see where that is.
I am in a subgroup named R1b1a2… which makes sense
as that would be a common Irish DNA classification.
It is Irish, not Viking, which could have been possible.
(A note on my familytreedna page say that ‘testing is
still in progress’ to 100 percent confirm my grouping.)
So, I guess I am still waiting for final subgrouping.

2. The Family Finder DNA test. (cousin finder).
This test is the ‘autosomal’ DNA test for males
or females. It is a fairly new type of test.
It tests both the fathers and mothers line of DNA
that you have inherited back for 4 generations or so.
The results are general, and it makes a good guess
as to your ethnic/geographic origins. I expect it will
be refined over time, but it is interesting and simple.

My Results, as expected 90 percent Western Europe/Ireland.
Unexpected is an 10% percent Middle Eastern finding.
This could be Palestinian, Jewish, Bedouin…. and
we have no idea where this comes from…perhaps from
my paternal grandmothers side, which is German and a
little sketchy as to information, with many early deaths
in the family. I am trying to get each side of the
family to test, to confirm or deny that theory.

Matches. I have much to learn, but my DNA page at
familytree.com lets me click a button to find people
who match my DNA, at different levels. I tested
37 markers in my Y DNA, and whoever matches the most
of those markers, would likely be the closest relation.
If they have the same surname as me, all the better.
I was surprised by all the matches that did not have
my surname however. I’ll need to think about that for
a bit.

Exact Match
I do have one other family member who tested 12 markers.
They matched me exactly for 12 DNA markers, so that
proves the test accurate so far… His genetic distance
is listed as 0 at the 12 DNA marker level. The 0 means
that all 12 markers were the same for each of us. If one
marker was different, we would have a genetic distance of 1.
(Today, 37 markers is the recommended minimum for testing.)

Conclusion to Date
So far so good. I am testing people on both sides of
my family tree (mothers and fathers family) to see
where the unexpected Middle Eastern heritage comes
from. As more people test each day, some details will
change in my reports, but I understood that when I
started.
I am still contacting people who have very close DNA
matches with me. Also slightly curious to see if
there is a DNA relationship between O’Loughlin and
MacLoughlin in Ireland. Nacy Cleary, founder of the
first county heritage center in Co. Clare, thought
that there might have been a close relationship
with the OLoughlins of Clare, and the MacLoughlins
in the north of Ireland.

So goes the state of Irish DNA in my house so far.
The DNA testing group that I started 10 years ago
is called ‘Irish Families’ at Familytreedna.com
It is open to all interested parties.

More to come on Irish DNA, as I discover it,
and of course, notes on the Irish genealogy
books I have written over the years…
