[8] Sveini ‘Sveinn’: The prose of Knýtl identifies him as Eiríkr’s great-grandfather, Sveinn tjúguskegg ‘Fork-beard’ Haraldsson, king of Denmark 985/6-1014. It is unclear what dominions he could have held in Wendland, since his dealings with the Wends were mostly hostile, and he was forced to ransom himself from Wendish captivity. See the summary of extant sources of information on his life in ÍF 35, lxxxvii-xc. For the alleged authentic claims of the st., see ÍF 35, xii.
