Doctor to Marry His Own Daughter, Create Rift in Time and Space | GeekDad | Wired.com: "David Tennant is engaged to Georgia Moffett. Tennant very popularly played the 10th incarnation of The Doctor on BBC’s long-running Doctor Who. Moffett played his daughter (actually a quasi-clone based on his DNA) in one episode during his tenure. As if that wasn’t strange enough, Moffett is also the real-life daughter of Peter Davison, who played the 5th incarnation of The Doctor."
