Recommended additional deep ancestry testing for men here with the interest and funds for this:

Upgrading to 67 markers for deep ancestry purposes can be useful in helping to better establish
relationships and time calculations to a common ancestor.  However, we now have a large number of
DYS388=13 samples, and the full 67 markers seem to have no specific use for them for deep
ancestry subgrouping here.  However, the additional markers may be useful within a surname project in
establishing family branches.  By way of exception, additional Italians and Hispanic men are needed
to upgrade to 67 markers in order to determine when they split from their cousins in northern Europe.
And the same can be said of the Turkish and Iranian men here.

All tested persons in the DYS388=13 group have tested positive for the P303 SNP which characterizes G2a3b1.
The outcome of such testing for all the samples listed below is very predictable as P303+ and testing, in my
opinion, unnecessary.   SNP testing can be ordered as what is called the deep clade SNP test in the
haplotree section of the individual Family Tree DNA results page.  P303 (G2a3b1) is included in this deep
clade test. 

There is no hint that the persons on this page are positive for U1, which characterizes a subgroup
of P303 (G2a3b1a).   In earlier testing DYS388=13 samples are negative for U1.  Little is known of the
coverage of the men on this page for L42 (G2a3b1b).   It is desirable that more persons on
on this page should test for it.    Little is known of the coverage of L139 (G2a3b1c) and confirmation that it
occurs within DYS388=13 persons would be desirable before additional persons test for this. These SNPs can
be ordered on the Family Tree DNA results page in the Order Tests section as an advanced test.  They will be
found at the top of the SNP list for $29US each.  These tests will eventually be added to the G deep clade test.  
Only one person from a surname group needs to test for SNPs as everyone else in the surname group will have
the same findings.
