[All]: Sæmundr Sigfússon inn fróði (d. 1133) was Jón Loptsson’s grandfather. His Lat. history of lives of the kings of Norway is no longer extant (see Introduction). The ten sovereigns who descended from Haraldr hárfagri enumerated in the poem so far include the jarls of Lade (Hákon, Eiríkr, Sveinn and Hákon) but not Sveinn Álfífuson, the son of Knútr (Cnut the Great). The jarls of Lade traced their ancestry to Haraldr hárfagri through a female line (see ÍF 26, 136-7, 142 and Genealogy II.b in ÍF 28).
