Sir Francis Stuart or Frank Stewart (1589–1635), was a Scottish sailor, aristocrat, English Member of Parliament and courtier.
He gave evidence in February 1606 in the Star Chamber of witnessing Anne loosen her clothing for dramatic effect.
Sir Thomas Howard, Master of Prince Henry's Horse, sent him a letter bordering on sedition, which was delivered by Stuart and William Ramsay, a servant of the king's bedchamber, to Viscount Haddington.
[6] He was sent to Spain in May 1623 during the Spanish Match to carry the patent to make George Villiers Duke of Buckingham and Earl of Coventry.
He wrote to Buckingham that Stuart was bringing a box of jewels including a pearl necklace that he had given to "poor fool Kaite".
Four head dresses brought by "Franke Stewarte" would be too precious and were "not fit for a subject", and they should give one to the Queen of Spain, or bring all of these pieces "hoame again".
Sir James Bagg of Saltram House, an admiralty official at Plymouth resented his apparent influence at court, and said he was a "demi-god" aboard the Lion.
[18] An incident in July 1627 near the Azores where Francis avoided a Spanish fleet in conditions of poor visibility was widely reported.
