About us


MAY 2005
Haplogroup I-L38, then called I(x), was first described in May 2005 on the Genealogy-DNA list at Rootsweb.com. This consisted of several conversations between (haplogroup J expert) Bonnie Schrack and (haplogroup I expert) Ken Nordtvedt.
Bonnie Schrack wrote on the 23rd of May a message with the subject: "New cluster? (was maybe I1b, maybe J2)".
In this mail the STR characteristics of I-L38 were pinpointed right from the start:
... -- this is exciting! We seem to have a new cluster here. Not quite as rare a haplotype as we had thought. Each and every one of these haplotypes I've selected from the results list have the 8 10 10 12 at 459a,b, 455 and 454. ... Eight have been tested at YCAII and 7 of those have 19,19.

MAY 2006
In his doctoral dissertation Felix Schilz published STR values of bronze age bones out of the Lichtenstein cave in Osterode-am-Harz, Germany.

JANUARY 2007
Jim Cullen identified the Lichtenstein samples as I1b2 (as I-L38 was called then).

2008
Ken Nordtvedts’ 2008 modal values spreadsheet determines 3 I2b*-STR clusters,A-, B- and C- separated by DYS448.
On a SNP level, it only was known at this time that I2b* was S23+, S30+, S32+, S33+; but M223-.
Comparing STR values Ken Nordtvedt calculated that I2b* originated about 4500 years ago.

SEPTEMBER 2008
Hans De Beule wrote an article on I-L38: Origin, Distribution and Migrations of I2b*-Subclades; publishing a median joining network and the first distribution map; both based on SMGF and Ysearch data. The frequencies and STR diversity drew special attention to the UpperRhine region. Later this article was followed by others - all articles were published together in http://rjgg.molgen.org/index.php/RJGG/issue/view/11/showToc and http://rjgg.molgen.org/index.php/RJGG/article/view/92

25 DECEMBER 2008
The SNPs L38/S154, L39/S155, L40/S156, L65/S159 were added to the ISOGG tree thus creating a new branch I2b2 (or I-L38).

FEBRUARY 2009
Tim Weakley started the FTDNA I2b2-project (as I-L38 was called then) - 38 members joined the first month.

2010
Hans De Beule set up this Website dedicated to I-L38 to harbour the latests finds on I-L38.

MAY 2012
In 2012 it became clear that SNP L533 separates I-L38. I-L533 was the first known subclade of I-L38.

AUGUST 2013
The 23andme results of two I-L38 project members: Stephen Prata and Andy Marotta, showed they shared the same L69 mutation, making I-L69 the second known subclade of I-L38.

SEPTEMBER 2013
One of the FTDNA I-L38 project members (Deterding) took the Geno2.0 test and turned out to be F780, indicating a possible 3rd subclade of I-L38.

NOVEMBER 2013
Ken Nordtvedt published a I-L38 STR tree at his website.
http://knordtvedt.home.bresnan.net/ - the website is temporarily removed at the moment

FEBRUARY 2014
Britain DNA published the Chromo2 results (14.200 SNPs) results of 2000 anonymized samples; 14 of the 2000 samples belonged to haplogroup I-L38/I-S155. Fifteen mutations separated this I-L38 group: S2606; S24121, S2488; S10269; S11558; S12480; S12547; S15855; S19763; S21118; S22679; S24647; S25490; S27697; S4556

JUNE 2014
Based on the Britain DNA data Ken Nordtvedt published a Chromo 2.0 L39/40 SNP network at his website .

JANUARY 2014
Stephen Prata added an extended I-L38 network analysis to the I-L38 website
https://sites.google.com/site/haplogroupil38/median-networks

NOVEMBER 2014
Hans De Beule requested ISOGG to add S2606, S24121 and F780 to the ISOGG tree, thus linking the ISOGG tree to recent FTDNA and Britain DNA results.

JANUARY 2015
FTDNA I-L38 members were regrouped (from a STR based grouping to a SNP based grouping).

APRIL 2015
The FTDNA I-L38 project welcomes its 300th member (Mr. Volokhin)

JULY 2015
Stephen Ralls added a research paper to the I-L38 website describing how I-L38 (21-14) is determined by SNP block SUR66-69.
Later YFull would label this group I-Y18919 (see jan 2016).

OCTOBER 2015
Mikhael Arzamanov points to the facts that the FTDNA Volga Tatar project contains several I-L38 members that have a characteric DYS439=10 value.This group appears to be the most eastern I-L38 branch.

JANUARY 2016
YFull launches version 4.01 of its experimental tree. Thanks to uploaded BigY results of I-L38 project members the resolution of the I-L38 tree has increased greatly. Among others Y18919, Y18921 and PH1237 were added to the tree.
