I see another company has also increased their test to a 43 marker test. http://www.dnaheritage.com/markers.asp This address explain some of the marker and the expected results. Hopeful Family Tree will also extend to a 43 marker soon. I have tried to to see if it has Surname project like FTDNA does but if so there is no Couch's listed. But there is some good reading at this site. I took the 37 marker test that FTDNA has and it should be back this week. They had it and a couple more scheduled for the 21 and then extended for 10 days. Guess we will just see what happend in the next day or two. But I will compair My results with what They are listing on this address.
