 The first bishop to be named in the chronicle is Roolwer himself, and the form of his name preserved by this source suggests that his name is a garbled form of the Old Norse "Hrólfr".The chronicle states that Roolwer was the bishop before Gofraid Crobán's reign, which could either mean that he died before the beginning of Gofraid Crobán's rule, or that Roolwer merely occupied the position at the time of Gofraid Crobán's accession.Roolwer's recorded name may be evidence that he is identical to one of the earliest bishops of Orkney.
