Auðhildr - Erik's parents? Eril & the daughter of Thorliot vs Edmund & the daughter of Frakok

Cawley's Medlands cites the Ornekinysaga as having the parents of Erik as
'ERIL Streita & his wife
Audhild [daughter of Thorliot.]

"Orkneyinga Saga records the marriage of “Earl Rognvald…his daughter Ingerid” and “[Eirik "Stay-Brails" Eiriksson Eirik Stay-Brails]”[917].
>>>>m (Sutherland Spring 1156) [Eirik "Stay-Brails" Eiriksson ERIK] Slagbrellir, son of ERIL Streita & his wife Audhild [daughter of Thorliot." [http://fmg.ac/Projects/MedLands/SCOTTISH%20NOBILITY.htm#_Toc268450047 (Cawley's Medlands)]

Geni has the parents as
Edmund Eriksson de VINGULMARK, de SUÈDE Edmund Eriksson de VINGULMARK, and

Auðhildr Auðhildr Torleifsdotter
Daughter of Frakok Moddansdatter

The Geni profiles cite no sources. Does anyone have any to suggest that we shouldn't changes the names to those in the Orkneyingsaga and Medlands?
