With Sigrid Eyvind had two children mentioned in Egil's Saga: Finn Eyvindsson "the Squinter" and Geirlaug Eyvindsdottir. Finn married Gunnhild, daughter of a jarl named Halfdan and maternal granddaughter of King Harald. Their children included Eyvindr skáldaspillir, court skald to Haakon the Good.[8] Another son, Njal Finnsson, settled in Hålogaland; his daughter was Astrid Nialsdotter, who appears in the Hervarar saga.

Rannveig and Sighvat had a number of children: (1) Sigmund Sighvatsson, who became the father of Mord Gig, Sigfus of Hlid, Lambi Sighvatsson, Rannveig, the wife of Hamund Gunnarsson, and Thorgerd, wife of Onund Bill; and (2) Barek Sighvatsson, the father of Thord, the father of Stein.[9]
