m [firstly] ---. The name of Olaf´s [first] wife is not known.

Olaf & his [first] wife had two children:

1. CARLUS (-killed in battle 866). The Annals of the Four Masters record in 866 “Carlus son of Amhlaeibh” among those killed in a battle fought between "Flann son of Conaing lord of all Breagh…the men of Breagh and Leinster and the foreigners" and Aedh King of Ireland at "Cill Ua nDaighre"[1159].
2. EYSTEIN [Oistin] (-killed 875). [The Fragmentary Annals of Ireland record in [871/72] that "Imar son of Gothfraid son of Ragnall son of Gothfraid Conung son of Gofraid" and "the son of the man who left Ireland" [Olaf/Amlaib] "plundered from west to east and from south to north"[1160]. It is possible that this passage refers to Eystein or another son.] The Annals of Ulster record in 875 that "Oistin son of Amlaib, king of the Norsemen, was deceitfully killed by Albann"[1161].
