in the area inland from modern-day
Helmsdale where Clan Moddan had a power base After the death of earl
Magnus Erlendsson c. 1115 at the hands of his cousin Haakon Paulsson, the family of
Moddan of Dale played a significant part in the affairs of the
Earldom of Orkney. However, their origins are obscure. For a date in the mid-11th century the
Orkneyinga saga mentions that "Muddan", who was a nephew of a King of Scots the saga calls
Karl Hundason, became
jarl of Caithness. He had not held this position long when he was killed by Thorkel "the Fosterer" Sumarlidason, an ally of Earl of Orkney
Thorfinn Sigurdsson. Thorkel was able to approach Muddan's base in
Thurso because "all the people of Caithness were faithful and loyal to him". It is far from certain that Helga's father Moddan was a descendant of this earlier namesake, and there is no suggestion that Moddan was a jarl, but his son Ótarr apparently was. Furthermore, Ótarr also had his base at Thurso. Whatever their origins, in addition to the titled Ótarr, Helga's siblings were, Angus "the Generous" and her sisters Frakkök and Þorleif. These children had both Norse and Gaelic names, whereas Orcadian families tended to have exclusively Norse names. It is thus likely that Helga's ancestors were of mixed heritage with her father being of Celtic origin and her mother possibly having a Norse background and related to the
jarl Óttar who was killed in 1098 fighting in
Man. The saga describes Helga as the mistress or
concubine of Earl Haakon, but has nothing to say about the mother of Haakon's other named child,
Páll. Sellar (2000) suggests that a degree of polygamy appears to have been acceptable among high-status families in Norse Scotland and that the distinction between wives and concubines may not have been rigid. ==Children==
