Kenneth, to find your ancestors (and use your DNA to help) it would be a good idea to start by entering profiles for your parents to WikiTree. On your profile click on the link that says [father?] and add what you know about your father, his birth date and where he was born, his death date and location if he's no longer living. Then do the same for your mother. Once you have profiles for them, in the same way add profiles for each of their parents, your grandparents. As you build your tree, WikiTree will add your DNA test information to your ancestors' profiles (so any cousins who see the profile will know that you have a DNA test on Ancestry they may match). Then look to see if any of your Ancestry DNA matches have trees that include any of your ancestors.
