What topic did you pick? What sources did you use?

I am going to do my project about my Grand father from my moms side of the family i am going to interview him about how his life was while he was in the Vietnam war and how it had changed after he came back from the Vietnam war. I am also going to interview my great grandmother about her memorable moments in history. I am also going to see how far back i can trace my family. I used sources like Ebco and Wikipedia.
