In or around 1488 William Stewart of Baldorran was appointed Royal Bailie of the Crown Lands of Balquhidder.

A baillie (alternative spelling bailie, from Old French) was a local civic officer in Scottish burghs, approximately equivalent to the post of alderman or magistrate (see bailiff) in other countries.

[2] William Stewart did much to restore prosperity to his family, ruined by the events of 1425 and the execution of his great-grandfather the Duke of Albany.

He succeeded in expanding the family estates, adding parts of Upper Strathgartney and eventually most of Balquhidder.

They had two children: His second wife was Marion Helen Campbell, Of Glenorchy, daughter of Colin Campbell, 1st of Glenorchy, whom he married on 5 October 1498, and by whom he had three children:[3] In the portioning of Balquhidder which took place during the sixteenth century, the descendants of Sir William Stewart of Baldorran gained hereditary tacks of land.
