About us

The objective of the R-L21 Walk Through the Y-2009 project is the discovery of SNPs downstream of R-L21 that can be well correlated to the many R-L21+ haplotype clusters, as listed on this website. This effort is being directed & managed by Thomas Krahn. The project is open to anyone who has been tested by FTDNA & tested L21+(derived). THE PRIMARY GOAL of our project is funding representative participants from each cluster for the direct sequencing necessary for SNP discovery. Contributions in any amount are welcome & contributions can be made at this website via the FTDNA general funds contribution link.  ANYONE WHO HAS BEEN TESTED & IS DERIVED (+) FOR L21 & IS WILLING TO FULLY FUND THEIR OWN TEST IS WELCOME!  The cost is: $950 US per participant for public status and US $1,500 US for private (non-public).

GUIDELINES FOR PARTICIPATION AND CONTRIBUTIONS: There are several steps involved in funding & selecting a candidate for testing, as follows:

1) Any man who can pay the entire cost for testing himself is welcome in the project. There are a number of requirements to be satisfied prior to making payment. First, an application must be completed & forwarded to Thomas Krahn, & no payment should be made without receiving his prior approval. Mr. Krahn will have final say in approval of any applicant for testing. The objective for testing is the discovery of new SNPs that can be associated with specific ethnic/cultural/geographic heritage, so those candidates with clear pedigrees that can be traced to specific European origins will receive the highest priority. Another priority is selection of those men who already have clear indicators of their extended haplotypes & haplogroup subclade. Those who have already tested a minimum of 67 STRs & a full Deep Clade SNP test will be given the highest priority. Any candidate considered for testing must at least have R-L21+ results, but prior testing of M269 & all of its downstream SNPs is preferred. SNP testing from any direct to consumer retail testing organization is acceptable.

2) Individuals interested in WTY testing for a particular individual or cluster will need to work with a volunteer coordinating WTY participation for the candidate or cluster of interest. The coordinator or coordinators work with interested individuals to select one or more suitable candidates for participation and to obtain commitments to fund testing from interested persons. Any candidates selected for possible testing should first complete an application with the project through the following link- WTY Application Form.  Once Mr. Krahn approves candidates for testing, it is the responsibility of coordinators to work toward funding the candidate or candidates. Ideally, prospective donors will already have committed the necessary funds before the candidate applied, and the coordinator(s) need only call upon those who have pledged to fulfill their commitments at that point. The project's group general fund mechanism may be used to gather funds. Donors may use a credit card or PayPal account and the following link to make their contributions - GENERAL FUND CONTRIBUTION

3) Selection of a suitable candidate for testing by a group of contributors can be a time-consuming process. In order to reach consensus in selection of a candidate, those who wish to cooperatively fund a candidate should have nearly identical goals for the testing. Often many of the individuals interested in a particular cluster are well known to one another, & recruitment is managed through existing email contacts & project websites, as well as discussion lists & forums. PLEASE note that this entire process is considerably more complex than simply ordering & paying for STR or SNP testing. This is a discovery project, & any results of value will become part of a revised phylogenetic tree, with implications for European history & prehistory. Various & sundry implications for L21 have been proposed, but additions to the phylogenetic tree structure will be immensely helpful in suggesting more recent historical implications. Origins for L21 & subclades have been proposed for the Beaker Folk, as well as the historically poorly documented Celts of central & western Europe.
