FTDNA Long form

FTDNA is starting to share their y-Haplogroup Long Form info again after hiding it last summer (shortly after they switched to reporting what they first called "Terminal SNPs" and what is now called "Short Hand")

This should be good news - but it is not.  Here's why:

  • ISOGG yTree

    • THE standard reference for the y-Haplogroup Tree (yTree)
    • Publicly available for all users - world wide
  • FTDNA yTree

    • Distinctly different from ISOGG’s yTree
    • Not available in tree form - publicly or to customers
    • Long form info now displayed with reported short hand on Project ySNP page
    • Unnecessary confusion

Here is my own long form - from both ISOGG & from FTDNA:

ISOGG:  R1b1a2a1a2b1b    http://isogg.org/tree/ISOGG_HapgrpR.html
FTDNA:  R1b2a1a1a1a3a4  https://www.familytreedna.com/public/barton/default.aspx?section=ysnp

Ugly!  Three differences in the first 6 digits and completely different after 9 digits - even to the point of not having the same number of digits (13 at ISOGG vs 14 at FTDNA)  Both versions are based on my short hand - R-L196.

So - be prepared for lots of questions and user concern.  Sigh.

Until FTDNA can arrange for ISOGG and FTDNA yTree alignment, they should hide their long form info.

Haplogroup Nomenclature

Hi Terry,

In one of my project result tables, I post FTDNA's short form, their long form, AND the old YCC/ISOGG 2008 format.  At some point the SNP haplogroup tree is going to solidify, but until it does (and we can go back to using a settled "driving directions" format), it's nice to have a familiar "E1b1a8a" to at least know what general neighborhood we're talking about.

My Cowart ancestry

My great grandmother is Marintha Cowart, daughter of Eleazar Lewis Cowart, Jr. (1835-1916) & Eleanor "Ellen" Hendrix, of Emanuel Co., Ga.
Marintha & Eleanor Hendrix Cowart are both in my direct maternal line. My mtDNA is U5a2aid at FTDNA & U5a2a2 t 23&Me.
I am looking for ther Cowart or Hendrix descendants with U5a2aid or U5a2a2.

Haplogroup Nomenclature

Mark - I agree that it's unsettling to not have a stable reference and it's great that you provide multiple references of the Haplogroup.  However, I do wonder if using the very old 2008 YCC/ISOGG tree is helpful - compared to providing the current ISOGG tree. 

I do agree that whatever Haplogroup reference we report will be confusing, as ISOGG, FTDNA, yFull, 23andMe and ancestry,com are not in alignment - which means that the same "last SNP" underlying your reported haplogroup is very likely to have a different long-form at one or more of the other yTrees.  And, the trees are quickly changing - meaning that even at the same reporting location, your long-form can be differnt than it was the last time you looked. 

Given the confusion, I choose to use ISOGG as my reference - as it is openly reported, uses available information from all vetted sources, and is done by a large group of dedicated citizen scientists.  

  • FTDNA does not openly report their yTree
  • yFull uses only data from tests they have analyzed themselves
  • Both 23andMe and ancestry.com use out-of-date yTrees for their reference.

William Benjamin Cash

I am trying to find the lineage of William Benjamin Cash, b. 24 APR 1855 in Kanawha County, WV. DC says father was William Cash of Alexandria, VA and grandparents were Lee and Statia Cash, probably born about 1795. If anyone can help me with this it would be great!!

Thanks, Cindy

This is our projected great grand parents and we are searching for other descendants to them among our matches etc any help would greatly appreciated as we know nothing on our paternal new found side at all.
