Goals of this project:

(1) To research the haplotypes, SNPs, and geographical and historical origins of the different subgroups of the DF13* 9919 superfamily.  These men have several persistent signatures that include 459=9-9, YCAII=19-19, and for many of them, the very slow mutating marker value 640=12, as Mike W. described here:

http://tech.dir.groups.yahoo.com/group/R1b-L21-Project/message/14535

There is a good chance that SNPs under DF13 will ultimately be found for these men, unifying them in some way - or possibly separating some of them from others.  Because they have strong, persistent signatures with the "stubborn" 640=12 shared between many of them, their doubled 9s and doubled 19s are probably clues to a common origin, rather than just something that happened by luck to men in entirely different haplogroups.  

Note:

The largest haplogroups under DF13 (parallel to each other and downstream from DF13):

DF49

L513

Z255

Z253

DF21

DF41

L1335

CTS4466

Z251

Some small haplogroups under DF13:

L371

L144.1

L679

L96

For reference, here is a summary of where you can research the STR patterns of the nine largest haplogroups downstream from DF13, plus the four small ones:

Z251+, see R1b-L21_Haplotypes spreadsheet.  As far as I know, Z251 doesn't have its own project yet.

There are several signatures:  251-11, 251-1124-9, 251-11EE, 251-555-lrw, and 255-711.

L555 and L583 are subclades of Z251.

L144, with at least two separate mutations and possibly a back-mutation in the Kendall family

Coming soon, CTS2457, awaiting placement on ISOGG.  Probably a smaller haplogroup similar to the last four.

There are also several private SNPs (L564, L580, and so on) under DF13, not known to be sons of any of the major or minor SNPs.

----------

Someday, something like the following will be included in the haplogroup project list above, and we'll be able to replace "???" with a defining SNP:
