I decided to join the Agnew surname project. I want the DNA compared specifically to other Agnews.That does not preclude other matches because the online privacy statement says the DNA is compared to the entire database. I suggest you submit any questions to their discussion forum. I will probably submit to the Scottish projects etc. which have a broader objective. By the way, I decided on the 37 marker DNA test because the more markers which can be matched, the closer the relationship.I have been doing a lot of reading but I am not an expert!
