Alexander de Kylwos written alternatively as Frylquhous, Kylquos, and a variety of other forms was a Scottish churchman and prelate active in the second half of the 14th century. He is known to have held senior positions in three bishoprics, and senior offices in two, before being elected and appointed Bishop of Ross in 1371. Though his episcopate is relatively obscure, he seems to have spent almost all of it inside or around his province, was closely associated with William III and Euphemia I, successive rulers of Ross, and was an associate of the famous Alexander Bur, Bishop of Moray, during the latters struggle with Alexander Stewart, the son of the King later known by the nickname Wolf of Badenoch.
He may take his name from Kilwhiss near Auchtermuchty in Fife. His family is obscure, but it is known that during his time as Bishop of Ross, probably in the 1390s, he brought one John de Kylwos clearly a relative into his diocese, as the Subdean. Alexander was certainly born in or more likely a good period before the year 1326, because he is known to have been a priest in 1350, the minimum age for which wasyears old.
