Ælfgifu 'Edith' (Sigurdsdóttir of Ossory), Lady of Atholl (wife of Malcolm II) - The name Of Malcolm II's wife? Blanaid, Aelfgifu or NN?

If not NN, as Medlands http://fmg.ac/Projects/MedLands/SCOTLAND.htm#DonadaM1FindlaechMcRor... tells us, then

BUT
B) Supposed additional daughter [of Brian Boru] (probably falsely attributed):
[She] is stated without evidence to have been a wife of Malcolm II, king of Scotland [Newman 144, 161 states that a daughter of Brian (name not provided) was married to Malcolm II, without providing any supporting evidence. This alleged daughter has been supplied with the name of "Blanaid" in some databases, evidently based on certain works of historical fiction written by novelist Morgan Llywelyn which used Newman's book as a source. This supposed daughter is absent from other recent histories of both Ireland and Scotland that would have been expected to mention the marriage if there was any good evidence for it, and the existence of this supposed daughter cannot be accepted based on any currently known evidence.] Newman = Roger Chatterton Newman, Brian Boru, King of Ireland (Dublin, 1983).

SO
Might her name be Aelgifu / Aelfgifu?

ID: I190964

Birth: 962 in Fordoun, Kincardineshire, Scotland
Father: Sigurd [<^>v] de na Ossory b: ABT 930

* Married: 983 in Fordoun, Kincardineshire, Scotland
Children

1. Has Children Doda [@ <^>v] de Falaise b: 985 in Falaise, Calvados, France

BUT
B) I can find no corroborating sources for this beyond the unvalidated: http://www.wikitree.com/wiki/Gunnarsson_Queen_of_Scotland-1; and the above link appears not to work. Is there a possibility of a confusion because a daughter of Malcolm married a Sigurd (not from Ossory, as far as I know - although that Sigurd's mother was supposed to have been Irish)?
