Hi Derek. If I'm interpreting you correctly, I think what you want to do is go to your father's profile, open the edit window, make sure the 'Still Living' selection is checked under Death Date, and then add his e-mail address in the very last field in the window. That causes an invitation to join WikiTree to be sent to his e-mail address, and then he can follow the prompts to create his own account. Once he does that, he will automatically become manager of his own profile, and he can add his DNA data. And after he has his own account, you can add each other to whatever trusted lists you wish.
