The nobles of Ulster argue over which of them is to be his foster father, until the wise Morann decides he should be fostered by several of them: Conchobar himself; Sencha mac Ailella, who will teach him judgement and eloquent speech; the wealthy Blaí Briugu, who will protect and provide for him; the noble warrior Fergus mac Róich, who will care for him and teach him to protect the weak; the poet Amergin, who will educate him, and his wife Findchóem, who will nurse him. He is brought up in the house of Amergin and Findchóem on Muirthemne Plain in modern County Louth (at the time part of Ulster), alongside their son Conall Cernach.
