[4] Hôkonar ‘of Hákon’: Hákon Eiríksson was the oldest son of Eiríkr jarl Hákonarson of Hlaðir (Lade) and Gyða, daughter of King Sveinn tjúguskegg Haraldsson of Denmark. Later he was Knútr inn ríki Sveinsson’s regent in Norway after Óláfr had gone into exile (c. 1028); there was thus to be a long history of hostility between Hákon and Óláfr.
