Ræfill: The name is known (also as Refill) from the fornaldarsögur (cf. Refill son Mæfils sækonúngs ‘Refill son of the sea-king Mævill’ in Þorsteins saga Víkingssonar ch. 8, FSN II, 404; one of the sons of Bjǫrn járnsíða ‘Ironside’, FSN I, 510; Reuillus in Saxo 2005, I, 5, 8, 4, pp. 338-9). It is used in several kennings and is most likely a derivative from ráf n. or ræfr n. ‘roof’, perhaps originally a nickname ‘tall, towering up to the roof’ (Björn Sigfússon 1934, 137). It is unclear whether this name can be connected semantically with ModIcel. ræfill ‘poor fellow’ and refill ‘strip of cloth’ (see ÍO: Ræfill).
