Relationships between historical figures could have been simplified or even fabricated in the text to give the impression that succession remained within the same family….Precise chronology is also difficult to assess from the Sagas….The conclusion must be that the tight family network described in the Sagas is unlikely to be correct and that the relationships shown below should be treated with considerable caution.
Unverified parents
Snorre names "Grelad, a daughter of Earl Dungad of Caithness…[and of] Groa, a daughter of Thorstein Raud" as mother of the five sons of Thorfin "Hausakljufer" m (941) THORFINN "Hausakliffer/Skullcleaver" Jarl of Orkney, son of EINAR "Turf-Einar" Jarl of Orkney & his wife --- (-soon after 977). He appears to have become Jarl of Caithness. [1]
Grelauga, daughter of Duncan, earl of Duncansbay, married Thorfinn Hausakliuf, and thus reunited in the Norse line the two earldoms of Orkney and Caithness. [4]
1.-Dotter, -Datter, -Dottir are all the same ending, meaning "daughter" in Scandinavia, and attached behind the father's first name. A woman kept her birth name all her life and did not take on her husband's last name as her own until about 100-200 years ago.
