Imagine that my male lineage is known all the way through time, not just
to John Cooley, who certainly had a father and grandfather...
John Cooley (1740-1811)
Edward Cooley (1763-1822)
John Cooley (1789-1866)
David Cooley (1815-1865)
Greenbury Cooley (1844-1899)
Joseph William Cooley (1867-1947)
McCabe Cooley (1899-1958)
Allison Claude Cooley (1925-2011)
Michael Hugh Cooley (1950-)
...and only that lineage--nothing that splits off into a maternal line.
The Y chromosome carries the male sex gene; therefore, only guys have it.
On average, a small mutation occurs every 150 years or so, known as a SNP.
I expect to learn from the upcoming test that 0-3 SNPs occurred between
Edward's birth and my own. These SNPs pass down to the next generation of
sons, some of which are a few generations old, and others that are
thousands of generations old. Just as we see a clear lineage above
(without all of the offshoots), we have a clear lineage here, but instead
of names of the persons born with the mutations, we have the names of the
SNPs the nameless men acquired:
L448
YP355
YP609
YP4248
Don has them, the Hackett tester has them, and it will be revealed that I
have them. Of course, these SNPs are 1000 or more years apart. That's
because only tens of thousands have been discovered. There are millions of
unknown SNPs floating around in each cell of every male's body.
My test will reveal several SNPs acquired since YP4248 (about 800 years
old) that Don and I have in common. They could only have come from John.
They will be named and one will be designated as representative of the
block. We'll end up with something like this:
L448 (c3200 years old)
YP355 (c2500 years old)
YP609 (c2300 years old)
YP4248 (800 years old)
Undiscovered (270 years old)
Here's Yfull's tree for L448 testers that have subscribes to the
interpretation services:

Scroll down to YP4248 and you'll see two testers, the Hackett tester
(first) and Don. Note that YP1100 "cousins" have origins in Sweden and
Norway and
YP618 cousins have some origins in Sweden, but that most of them have
British Isles origins. Of course, we don't know where our "Cooleys" were
800 years ago but it's beginning to look like we're getting close to the
period when our Norway ancestors crossed the North Sea, probably into
Scotland.
