In 1265 King Alexander III of Scotland ordered William Sinclair of Roslin to assist the King of England. In March 1290 William Sinclair of Roslin attended Parliament at Brigham. In 1292 William and his son Henry swore allegiance to King Edward I of England. William and his son Henry were captured at the Battle of Dunbar (1296). William was sent to the Tower of London, where he later died (1297).

[SINC481] Sir Henry Sinclair (born c.1297, son of William & Matilda), 7th Baron of Rosslyn, Commander of Knights Templar at the Battle of Bannockburn (24th June 1314), married Alice (daughter of John de Fenton, Baron of Fenton). He died 28th January 1336.

[SINC491] William Sinclair (born c.1307), married Rosabella. He was killed at the Battle of Teba, Spain, (25th August 1330), together with his brother John Sinclair and Sir James Douglas, whilst en route to Jerusalem carrying the heart of Robert Bruce. After the battle the survivors were allowed to return home with William's body and the heart of Robert Bruce.  William's body was apparently buried in an earlier church at Rosslyn, which is now the site of present village graveyard. What is thought to have been his grave marker is preserved in the present Chapel.
