although alan's marital alliance with ragnall had likely been welcomed by the scottish crown, the fact that the two were unable to quickly deal with amlaíb dub caused serious repercussions. the meic uilleim insurrection of 1228–1230, for instance, may have been a byproduct of the instability prolonged by alan's involvement in the isles. even so, alan's actions appear to have also led to the end of irish support for the meic uilleim. if he had indeed married rose in 1229, for instance, this union may well have compelled her father to disassociate áed méith from lending support to the meic uilleim. whatever the case, uí néill ambitions in the isles appear to have come to an abrupt end with áed méith's death the following year, after-which the latter's kin became embroiled for years in a struggle against the meic lochlainn over the kingship of tír eoghain.
