Carol (Seejay51) stated that Sitric (she named him "Halfdansson" implyingthat he was son of Halfdan?) was father of Sitric King of Dublin & York.Todd Farmerie stated that the name of his father was not known, andnaming one's son after the father was not common custom. Todd did statethat Sitric, King of Dublin & York, was grandson of Inguar of Dublin (whoI take to be another name for Ivar the Boneless).
Stewart Baldwin, reviewing a book "Scandinavian Kings in the BritishIsles, 850-880" by Smyth, stated that Smyth said Sitric's father was alsonamed Sitric (d. 896). Stewart Baldwin did not agree with the name (itwas not the practice to name one's son after one's self), but did verifythat Sitric King of Dublin & York was grandson of Ivar.
Stewart Baldwin, on his website entitled "The Kings of the Isle of Man",in the notes under "Table 1: Kings of Dublin" states that Ivar had a sonSitric, who died in 896. However he does not connect that Sitric withSitric King of Dublin & York; EXCEPT to say that Harald King of Limerick,if not son of one Sitric, could be the son of the other Sitric, whichseems to imply a relationship between the two Sitrics.
Note: The sources seem to agree that there was one generation betweenIvar (the father) & Sitric (the son). Obviously this generation wasnamed something, and "Sitric" is the only name given (although the nameis questioned by some), so I am using it, even if possibly/probably wrong.
