Hello, all CTS6433 has been known to be parallel to CTS1977 for a long time. It was simply a problem in the numbering of the rows. This mistake has been fixed. Thank you for pointing it out. Please let me know if you catch anything else. You may always refer to the ISOGG tree if you have any questions as well: http://www.isogg.org/tree/ISOGG_HapgrpI.html .  Aaron Torres Today's Topics:   1. Re: Y-DNA-HAPLOGROUP-I Digest, Vol 9, Issue 455 (Emil Crawford) I read it the same way  you do.  It seems to me that CTS1977 (for example) should be 1.2.2.1.1.2 instead of 1.2.2.1.1.1.2 if it is actually parallel to, as opposed to downstream of CTS6433.  My understanding from looking at Nordtvedt's charts is that it is parallel to rather than downstream of CTS6433.  It is a bit confusing to try to decipher for the novice hobbyist (like me) the way it is numbered.
