FamilyTreeDNA currently has specials on the pricing of their Y-DNA tests and upgrades.
These tests are good for researching your roots over the centuries and millenia. How far does your father's surname go back?
You don't have to display your real name and can use a different email from usual if you prefer.
You might help solve one of our research projects or help someone else find their family. The lowest level test is fine for getting started, but the Big-Y 700 marker test provides most information long term.
There's no need to buy the Family Finder test if you've done an Ancestry test already. You can simply upload those results to FamilyTreeDNA, MyHeritage and GEDmatch for free.
