Elias II (also Helias, "Hélie", "Helyes" or "Élie") (died 15 January 1151) was the younger son of Fulk V of Anjou and his first wife, Eremburga, daughter of Count Elias I of Maine. There is debate as to whether he was ever count of Maine or whether he merely made a claim to it.
Fulk V of Anjou was only married once.
The text says that Fulk V of Anjou had a first wife, suggesting that he was married again. I think the system doesn't understand that implication.
