There is some uncertainty over the identity of this Member on account of the commonness of his name in Scotland. Often confused with Sir Walter Stewart - who was apparently a member of the Stewart family of Minto - Steward has also been identified, probably incorrectly, as a medical doctor. The identification given here rests upon the Member’s known position in the king’s Household and the fact that his sister is identified in contemporary sources as Anne, Lady Saltoun, daughter of Lord Blantyre.
Steward was a denizen by letters patent. A bill to naturalize him, Sir Francis Stewart* and several other Scottish courtiers was laid before the 1621 Parliament, but though it passed both Houses it was lost - along with much other legislation - at the dissolution.
No fresh election is known to have taken place at Monmouth, but in January 1625 another naturalized Scottish courtier, Sir Robert Kerr, was returned at a by-election for Aylesbury. This may have been intended to test the precedent established in the Steward case. The Parliament was automatically dissolved on James’s death, but the fact that Steward and Kerr were both returned to the 1625 Parliament suggests that the Court was keen to establish the validity of the return of naturalized Scots. Steward’s election was not challenged in 1625. A largely inactive Member, he was named to committees concerning concealed land (25 June) and excommunication (27 June).
Steward’s relationship with Buckingham appears to have soured by 1624, when the latter (now a duke) wrote bluntly that he would block Steward’s attempts to become a groom of the bedchamber as ‘I thought him not fit for it’.
Steward was employed in 1636 as captain of the Victory when this ship was used to transport the Spanish ambassador to England.
During the early 1640s, Steward repeatedly petitioned the House of Lords for protection against de Franchi while he tried to have the judgements overturned.
