Siptah

Akhenre Setepenre Siptah or Merneptah Siptah was the penultimate ruler of the Nineteenth Dynasty of Egypt. His father's identity is currently unknown. Both Seti II and Amenmesse have been suggested although the fact that Siptah later changed his royal name or nomen to Merneptah Siptah after his Year 2 suggests rather that his father was Merneptah. If correct, this would make Siptah and Seti II half-brothers since both of them were sons of Merneptah.
