  Marriage Notes:

"Sir William Sinclair, according to Father Hay1 (1 Genealogie of the St. Clairs of Roslin), was the son of Robert de Saintclair in Normandy, and his wife Eleanor, relict of Hugh, Lord of Chateauneuf, daughter to Robert, second Comte de Dreux, in France, by Joland of Coucy, his wife.

He was Sheriff of Edinburgh in 1266 and 1288-90, of Haddington 1264- 90, Linlithgow 1264-90, Dumfries 1288, and Justiciar of Galwythie 1288-89. He was guardian to Alexander, Prince of Scotland, 1279-81, who predeceased his father in 1283-84, and was a great favourite with King Alexander III., who granted him a charter of the baxter lands of Innerleith on 8 April 1280, and on the resignation of Henry of Roskelyn, a charter of the lands and barony of Roslin, on 14 September 1280. He was a member of the Parliament which met at Scone on 5 February 1284, and settled the succession to the Crown in the event of the death of King Alexander in.

In 1285 he was one of the embassy which went to France to escort the Queen elect, Joleta of Dreux, daughter of Robert, fourth Comte de Dreux, to Scotland. He was present when John Baliol swore fealty to Edward I. at Newcastle-on-Tyne 20 November 1292. From King Edward I. he had a grant of the annual value of 100 merks, and on 29 June 1294 was summoned with other Scottish nobles to assist England against the French, but instead, at a Parliament held at Scone, they resolved to enter into an alliance with France against Edward.

On the outbreak of the War of Independence he was one of the garrison who defended the Castle of Dunbar in 1296 against Edward I., and on its surrender, on 25 March 1296, was sent a prisoner to the Tower of London. He is said to have married Agnes, daughter of Patrick, Earl of Dunbar, but this is doubtful, and a certain Amicia, widow of William de St. Clair, dwelling in the county of Edinburgh, had a two years' protection from Edward I. on 7 April 1299. He had issue"
