Thank you very much for your email.
It does indeed look that you may qualify. In order to take part we would require you to fill in our online survey to collect and validate information with regards to the birthplaces of your 4 grandparents. They all need to have been born within a 80km radius in contemporary Germany or from an area that was part of a German state in the past (Pomerania, Western Prussia, Eastern Prussia, Posen and Silesia).

If you think you meet the criteria, please take our survey and upload your "Build 37" autosomal DNA results to put yourself forward and we will get back to you as soon as possible.
Once you have completed the survey we will check your information
and if you qualify you will be able to get a Living DNA account for free (within approximately 10 weeks) for your atDNA.
