Numitor

He was the son of Procas, descendant of Aeneas the Trojan, and father of the twins' mother, Rhea Silvia, and Lausus.

[3] Amulius also murdered Numitor's sons, in an effort to remove power from his brother for himself.

[3] Rhea Silvia was made a Vestal Virgin by Amulius, rendering her unable to have children on pain of death; however, according to myth, she was forcibly impregnated by the god Mars.

[4] Romulus and Remus overthrew Amulius and reinstated Numitor as king in 752 BC.

[5] ^ Ovid names his children as Lausus and Ilia[6] whereas Livy says Amulius had his two sons killed.
