This could be evidence that, in comparison to Muirchertach's immediate Norse-Gaelic predecessors in Dublin, his own regime lacked the expertise to ensure the vitality of the kingdom's commerce and currency. Annalistic evidence from throughout Europe indicates that the continent suffered from a resurgence of plague and famine during the first years of the 1090s. In fact, if the "Annals of the Four Masters" is to be believed, about a quarter of Ireland's population succumbed to pestilence in 1095. This source, and a host of others—such as the "Annals of Clonmacnoise", the "Annals of Inisfallen", the "Annals of Tigernach", and the "Annals of Ulster"—all single out Godred as one of the many mortalities. The "Chronicle of Mann", which also records Godred's death, reveals that he died on Islay. The fact that he met his end on that island could be evidence that Muirchertach not only drove him from Dublin, but from Mann as well. On the other hand, the possibility that Islay was an important locus of royal power in the Isles, combined with the evidence of his father's links with the island could instead be evidence against such an overthrow. Furthermore, the chronicle itself states that Godred was succeeded by his eldest son, Lagmann. On Godred's death, the "Annals of Inisfallen" accord him the title "" (translated variously as "King of Dublin and of the Isles" and "king of Dublin and the Hebrides", a remarkable designation in the fact that it is quite rare, and perhaps only elsewhere accorded to Diarmait mac Maíl na mBó. In the case of the latter, the title may emphasise Diarmait's achievement of stretching his influence from Ireland into the Isles. In Godred's case, the title may instead underscore Godred's expansion into Ireland from the Isles. The chronicle's record of Godred's death on Islay could indicate that the island formed a secondary power centre in the Isles. The fact that "Historia Gruffud vab Kenan" notes that Gruffudd travelled into the Isles to obtain military assistance from Gothrei could also be evidence that Godred's headquarters was located there. The record of Godred's death on Islay further suggests that he may well have been buried on the nearby holy island of Iona, the burial place of his like-named grandson, Gofraid mac Amlaíb, King of Dublin and the Isles.
