Father of Mine was the patriarch of the Family of Blood in the Doctor Who episodes "Human Nature" and "The Family of Blood". He possessed the body of a farmer (portrayed by Gerald Horan) in 1913 to find the Tenth Doctor and steal his near-immortal life essence. Despite being the head of the family, he allowed Son of Mine to take charge. He was the second of the family to take a host. After the Family was defeated, the Doctor wrapped Father of Mine in unbreakable chains made of dwarf star alloy and left him in an underground chamber.
