(First, I should say that I know this does get far afield from genealogy.
The idea is to see how our particular Cooley tribe is distinguished on the
Y chromosome from others. This allows us to see if a Cooley is one of
ours. The hope is that we will also be able to find someone with a
well-recorded lineage to a time prior to John who matches our Y. Sorry if
this is over a lot of heads. I try to make these posts as clear as I can.)
I don't like 23andme reports. But I've managed to create this from one of
their generic texts files. The SNPs are ordered from the most recent
mutations at the top to the oldest markers at the bottom. The presence of
the SNP is indicated by the change in the chemical at that location. In
other words, if there is no mutation there, the marker is said to be
negative. "I" means insertion and "D" means deletion. In other words, the
marker M17 is identified by its absence!

They tested a lot more SNPs than this, most of the ID'd by only a
reference number. My guess is that the significance of most of them is
unknown.
I can use this as a basis for sorting through Don's list.
