William Stewart of Grandtully

William Stewart of Grandtully (1567–1646) was a Scottish landowner and courtier.

Career
He was a son of William Stewart or Steuart of Grandtully (died 1574) and Isobella Stewart, a daughter of John Stewart, 3rd Earl of Atholl.

It is said that he was brought and educated with James VI at Stirling Castle. A royal charter of 1602 reflects this, noting that he was in the king's service "since his coronation". Stewart was described as a "page of honour" at court in 1585.

The chronicle attributed to David Moysie says that this man (described as the Laird of Grandtully, nephew of the Earl of Atholl) and his kinship friends, declared to James VI in 1579 that John Stewart, 4th Earl of Atholl had been poisoned at a banquet at a Stirling Castle.

He had an older brother, Thomas Stewart, who became Laird of Grandtully. William became Laird of Banchrie. Before his death in 1611, Thomas feued the lands of Grandtully to William, who was then known as the "feuar of Grandtully".

William Stewart became a gentleman of the king's bedchamber in May 1594. He helped save the king from the Gowrie Conspiracy at Perth on 5 August 1600 and James VI rewarded him with the forfeited Ruthven castle of Trochrie near Little Dunkeld and the barony of Strathbran. A privy seal letter of November 1600 describes him as a "daily servitor" of the king. He is said to have made additions to Trochrie Castle which featured his initials and heraldry.

He does not seem to have resided at court in London after the Union of the Crowns.

His home was at Grandtully where he refurbished St Mary's church with a wooden vault painted with vignettes around the year 1636. He also came to own Murthly Castle.

His portrait was painted by Adam de Colone and a copy of this picture still hangs at Murthly.

He died in 1646 and was buried at Grandtully.

Marriage and children
He married Agnes Moncreiff. Her monogram and heraldry appears in the chapel at Grandtully. Their children included:
 * Thomas Stewart of Grandtully (1608-1688), who married Grizel Menzies. Their daughter Grissel Stuart married John Drummond of Logiealmond.
 * Henry Stewart
