"...Helgi, the son of Ketill Flatnefr, nine-century Norse ruler of the Hebrides, was himself known by the Gaelic nickname of "Bjolan" (Beolain), nicknames being the usual second element in Norse personal names. Nor should we be surprised to find that Helgi Bjolan’s relatives brought Christianity to Iceland in the ninth century. The very survival of Applecross as an abbey on the coast of Viking Ross points to fortuitous Norse patronage. Helgi Bjolan is undoubtedly the namesake of the O’Beolains, since his father was ruler of the Hebrides (Applecross faces these) and his nephew was King of Ross. Beolain is certainly not a typical Gaelic name...
The main line of the co-arbial abbots of Applecross later became vested in the Earldom of Ross under the Normanized Kings..."
