↑ Svæinn Harallz sunr; Latinized forms of the name Sveinn are Suanus, Suenus, or Sveinus (Haraldi filius). The nickname tjúguskegg is a compound of tjúga "fork" and skegg "beard". Sweyn is so named in Fagrskinna chapters 27 and 41 (ed. Finnur Jónsson 1902–8, pp. 161, 206), in both cases in references to Astriðr dottor Svæins tiuguskægs.
