Perhaps coming from Fyvie in Formartine, from a family of Teesdale origin, Robert was Archdeacon of Ross and a student at the University of Bologna by 1269.
[2] He is found as a student at the University of Bologna on 5 December 1269, when along with one Alan de Edinburgh he gave a receipt for 20 marks to some Florentine merchants; in this appearance he is recorded as Archdeacon of Ross, a position which, under the Fortrose Cathedral constitution of 1256, meant he must have already been in deacon's orders, as this constitution made that a prerequisite for holding the archdeaconry.
[8] The bishopric was still in crown hands in June, but it is probable that Robert was consecrated by 6 August, the date of the meeting of the Scottish prelates with the papal tax collector at Perth.
[9] Bishop Robert appeared next on 16 September 1278, at Eddyrdor (now Redcastle), witnessing alongside three of his canons and Uilleam II, Earl of Ross, a grant to Beauly Priory.
[11] Bishop Robert de Fyvie swore fealty to King Edward I of England on 1 August 1291, along with the Earl of Ross and Henry le Chen.
