William Sinclair of Roslin

Sir William St Clair, 8th Baron of Rosslyn Succeeded 1331, died 1358

Married Isabella de Strathern, daughter of Malise, Earl of Caithness, Strathern, and Orkney. Malise had no male heirs and after William's death, his and Isabella?s son Henry was recognised as 42nd Earl of Orkney in 1369 and ten years later as the first St Clair Prince of Orkney. In addition to the titles inherited from his father, Henry also became Lord Shetland, Lord Sinclair, Lord Chief Justice of Scotland, Admiral of the Seas, Great Protector, and Keeper and Defender of the Prince of Scotland.After the death of Robert the Bruce, Sir Henry?s (7th Baron) two sons, William and John, were chosen along with Sir James Douglas and Sir Robert Logan of Restalrig to carry the King?s heart to Jerusalem and deposit it in the Church of the Holy Sepulchre. They never reached their destination; during a fierce battle with the Moors at Teba in Spain in 1330, William, his brother John, and Douglas were killed. The Moors were so impressed by the courage of the Scottish Knights that they allowed the survivors to take their dead - and Bruce?s heart - for burial back home.
