It is thought possible that Reinald had been in the company of Roland, Lord of Galloway, at some point, perhaps being involved with Roland's foundation of Glenluce Abbey in January 1192; again on purely speculative grounds, he may have had some involvement at Kinloss Abbey in the late 1180s. Reinald was a monk of Melrose Abbey when, on 27 February 1195, he was elected to succeed Gregoir as Bishop of Ross, an episcopal see whose seat at that time was located in Rosemarkie. His election was recorded and indeed celebrated by the Melrose Chronicle, written at the abbey:
This historian Richard Oram declared that his appointment "provided the crown with a dependable ally in an influential position, within a region where its authority continued to be challenged". The occurrence of the election at Dunfermline, a long way from Rosemarkie, was probably to secure royal control. Reinald, as "Bishop-elect", is found witnessing a confirmation by the king of a grant by Jocelin, Bishop of Glasgow, to Jedburgh Abbey on 4 July; it was issued at Jedburgh. Between his election and consecration, Reinald was found witnessing a charter by Bishop Jocelin to Melrose Abbey. The Chronicle of Melrose goes on to say that Reinald was consecrated at St Andrews by John, Bishop of Dunkeld.
Bishop of Ross
On 29 December the same year, Bishop Reinald was at Christchurch in Hampshire consecrating an altar. He witnessed two royal grants issued at Elgin to the Cistercian Kinloss Abbey on 31 July 1196. On 3 April, in a year falling inclusively between the years 1196 and 1207, probably 1199, he witnessed a royal confirmation of a grant by Thomas de Lundin to Coupar Angus Abbey; the confirmation was issued at Forfar in Angus. Bishop Reinald attended the legatine council of the Scottish church held at Perth in December 1201. He witnessed a royal grant to Hugh of Benholm of land in the Mearns on 5 April, either 1201 or 1202; this grant was issued at Kincardine. A papal mandate dated to 27 May 1198, instructed Reinald and the Bishop of Orkney to compel the Bishop of Caithness to stop preventing the collection of Peter's Pence, which Earl Harald Maddadsson had granted. This errant Bishop of Caithness was John; he was standing up for the peasantry of his diocese, as well as perhaps his own revenues; collection of the Pence had a strong history in Scandinavia, and John's resistance resulted in his mutilation by Earl Harald, who had the bishop's eyes and tongue cut out.
Death and succession
There is little more information about Reinald, and his role in the rebellions and warfare which took place in Ross in this period is unclear. The Melrose Chronicle recorded his obituary:
Professor A. A. M. Duncan has argued that Reinald was a friend of Roger of Howden, and that Reinald provided information to Roger regarding Rosemarkie and events in northern Scotland both in person when Roger visited Scotland and in a letter written to Roger around 1199 in the French language; Roger, it is argued, incorporated this material into his Chronica.
