Early showing himself the black sheep of the family, Stuart ran away from Oxford to Paris in 1768 at the age of 17, but was sent back. His father resolved to send him to India, and a writership in the East India Company was obtained for him.
In 1776 Stuart had been brought into Parliament on the family interest for Ayr Burghs; it was hoped he would make his mark in the House, and on 29 Feb. 1776 he made what seems to have been his maiden speech in support of Administration.
He died 17 May 1802.
