If you are a male descendant of a Drake with the surname of Drake, Familytreedna.com is running special pricing now on DNA testing. I would recommend more than the 12 marker test.You get more information with more than 12 markers.There's a Drake DNA Project ongoing as well.Please join the Project.
My male cousin submitted his DNA sample several years ago. It helped us get back 2 more direct generations from our brick wall. In my opinion the DNA testing is well worth the price.
