William Sinclair, 1st Earl of Caithness
William Sinclair (1410–1480), 1st Earl of Caithness (1455–1476), last Earl (Jarl) of Orkney (1434–1470 de facto, –1472 de jure), 2nd Lord Sinclair and 11th Baron of Roslin was a Norwegian and Scottish nobleman and the builder of Rosslyn Chapel, in Midlothian.
In The Scots Peerage by James Balfour Paul he is designated as the 1st Lord Sinclair, but historian Roland Saint-Clair designates him the 2nd Lord Sinclair in reference to his father, Henry II Sinclair, Earl of Orkney, being the first person recorded as Lord Sinclair by public records.
He was the son of Henry II Sinclair, Earl of Orkney and Egidia Douglas, daughter of Sir William Douglas of Nithsdale and maternal granddaughter of Robert II of Scotland. He was also the grandson of Henry I Sinclair, Earl of Orkney.
His father Henry, who had been a de facto Earl of Orkney, died in 1420; William travelled to Copenhagen in 1422 to establish his claim to the Earldom, but David Menzies was appointed instead, to rule as William's guardian until he came of age. In 1424, William succeeded in wresting de facto control of the earldom from his guardian, but it was not until 1434 that he was acknowledged as Earl of Orkney by King Eric VII of Denmark, Norway and Sweden, sovereign of Orkney.
On succeeding to the Earldom of Orkney, William had barely been in possession of it for a year when he was one of five earls selected to be among twenty hostages, proposed on 31 May 1421, for the redemption of James I of Scotland. When that redemption could not be obtained, he was then placed on the list of nobles who received a passport to visit James I, who was then a prisoner in England. The earl received a safe conduct for himself and twenty-four persons. James I returned to Scotland in 1424 and he was met at Durham by the Earl of Orkney as well as the Earls of Lennox, Wigtown, Moray, Crawford, March, Angus and Stratherne.
In 1423, David Menzies of Wemyss, chief of the Clan Menzies and uncle of William, was entrusted by King Eric with the administration of the Isles, and the Bishop of Orkney subscribed to this obligation as surety. However, due to disorder during the reign of Menzies, the government of the earldom was reinstated to the Bishop for seven years until the young Earl William could formally receive his investiture. However, the young William had taken the title of earl before receiving his investiture as he is styled as Earl of Orkney in 1426 at the assize in Stirling, and again in 1428 when he was present at Edinburgh dealing with a complaint made by his mother regarding the spoilation of her Nithsdale possessions.
In 1434, William crossed over to Denmark and King Eric granted investiture to him for the Earldom of Orkney. Earl William was also to hold Kirkwall Castle for the king and his successors. In the same year James I of Scotland's daughter, Margaret, was betrothed to Louis, Dauphin of France and Charles VII of France then arranged for Margaret to be escorted back to France. The King of Scotland ordered that all should be ready by 20 June, and William, Earl of Orkney had forty-six ships in readiness to transport Margaret and her train. The fleet that carried her to her future kingdom was commanded by the Earl of Orkney.
In 1446, the Earl of Orkney laid the foundation stone of the Collegiate Church of St Matthew, commonly referred to as Rosslyn Chapel. In the same year the Earl of Orkney was called to the Norwegian Riksråd to take the oath of Christopher of Bavaria who was the successor of King Eric of Denmark, Norway and Sweden.
