Matheson proposed that when Camden published his "Britannia" which included an account of the kings of Mann, genealogists saw the Latin "Olavus" (a Latin form of the Old Norse "Óláfr") and concluded that it represented the Gaelic name "Olbhar", "Olghair". However, the Scottish Gaelic form of "Olaf", "Olavus", "Olaus", "Óláfr", is in fact "Amhlaoibh", and the more modern "Amhlaidh". Matheson further proposed that Leod's father's name also equates to "Ölvir". So in Matheson's opinion, genealogists mistakenly attached Leod's father and great-grandfather to the Manx king Olaf the Black and his own grandfather, Olaf the Red. While Matheson's identification of the name of Leod's grandfather is now accepted, Sellar later disagreed with him on the name of Leod's father; proposing instead that it was more likely the Gaelic name "Gillemuire"—a name which appears on one of the four Gaelic-language genealogies.
