The séimhiú of mhór is odd, since mullach is usually masculine and so one would expect 'Mullach Mór'. Price recorded the pronunciation 'Mullawore'. Theoretically, it could be Mullach Corr. However, in addition to the difficulty of explaining the cited pronunciation, corr as an adjective in place-names usually means 'pointed' rather than 'round', which would certainly not be appropriate for the dome of Mullacor.
Mullacor is the 181st highest place in Ireland. Linkback: https://mountainviews.ie/summit/177/
