Henry Sinclair, 4th Lord Sinclair
Henry Sinclair (died 1513) was a Scottish noble and the 4th Lord Sinclair. In "The Scots Peerage" by James Balfour Paul he is designated as the 3rd Lord Sinclair, but historian Roland Saint-Clair designates him the 4th Lord Sinclair and references this to an Act of the Scottish Parliament in which he was made Lord Sinclair based on his descent from his great-grandfather, Henry II Sinclair, Earl of Orkney, the first Lord Sinclair. Bernard Burke, in his a "Genealogical and Heraldic Dictionary of the Peerage and Baronetage of the British Empire", agrees with  Roland Saint-Clair and says that Henry Sinclair was "in reality" the fourth holder of the title of Lord Sinclair. Early life. He was the son of William Sinclair, 3rd Lord Sinclair and Christian Leslie, daughter of George Leslie, 1st Earl of Rothes. Immediately after the death of his father, an Act was passed by the Scottish Parliament in his favour and which recognised him as "Chief of yat blude" and willing "yarfor that he be callit Lord Saintclair in tyme to cum", dated 26 January 1488–89. This Act was only a recognition of the Barony of St. Clair existing  in the person of his ancestor, Henry II Sinclair, Earl of Orkney and did not constitute a new creation. Notable offices.
