Early life
He was born c. 1555, the son of Sir John Stewart of Minto and Margaret Stewart, sister of James Stewart of Cardonald. His family descended from the Stewarts of Minto, a senior branch of the Clan Stewart headed by the Earl of Galloway. Walter Stewart was educated with King James VI under George Buchanan at Stirling Castle. He seems to have been a good rider, and excelled at mathematics, but did not share the king's wider intellectual interests.
In May 1580 twenty five gentlemen were appointed as "pensioners to attend the King's Majesty at all times on his riding and passing to the fields". The riding entourage included Stewart with, Captain James Stewart, Captain Crawford, the Master of Cathcart, Roger Aston, John Carmichael, James Anstruther, Patrick Hume of Polwarth, and John Stewart of Baldynneis. Stewart became a gentleman in the king's chamber.
Career at court
Between 1587 and 1593 Walter Stewart held the barony of Glasgow, in place of the young Duke of Lennox, and so he appointed the magistrates and Provost of Glasgow.
