Stewart was the younger brother of Robert, 1st Marquess of Londonderry, Castlereagh’s father, on whose interest he sat for a month in the Irish parliament for county Derry in 1800 before transferring to Lord Clifden’s borough of Thomastown. In September 1800 he was spoken of as a likely parliamentary candidate for Donegal, where he had resided for 18 years.1 Nothing came of this, and when Stewart was returned for county Derry in 1814 it was as a family stopgap, a replacement for his nephew Charles William Stewart. He retained the seat only until the dissolution, when he was replaced by his son Alexander Robert who had meanwhile come of age.
