Question

How can I add my Y-DNA test to my deceased half-brothers profile I just created?

Answer 1

Generally, you cannot add DNA for other people; however, since your brother is deceased, and if you manage his DNA data and the profile here on WikiTree, you can add this .

Go to his profile, and using the drop-down menu that his WikiID on it, choose the DNA option. Then choose the DNA Tests tab and follow the instructions there. (quick link)

Answer 2

Tom, your question was how to add your Y-DNA test to your brother's profile.

The system has already populated his profile with this information.

Did you mean that your brother also took a Y-DNA test?
