A devout Baptist, she and her family sheltered the rebel 9th Earl of Argyll when he was in hiding in London and fled with him to the Spanish Netherlands in 1683.
She hosted fellow conspirator Elizabeth Gaunt in Amsterdam and received a royal pardon for her activism in 1686, after which time records of her life cease.
At that time, it was recorded she was married to a prosperous sugar-baker in London and involved in the business, pursuing a debt owed by the nephew of the Spanish ambassador.
[1] After the Exclusion Crisis ended in 1681, King Charles II cracked down upon religious dissenters and this may have motivated Smith to take political action, since she was a devout Baptist.
[1] She was acquainted with the rebel Major Abraham Holmes and Presbyterian minister Robert Ferguson, who was known as "the Plotter" for his involvement with conspiracies such as the Rye House Plot and the Monmouth Rebellion.
He had printed pamphlets about the Popish Plot and Shaftesbury's treasonous text Speech Lately Made by a Noble Peer, consequently being forced to flee with his family to Rotterdam.
[8] In addition to her financial support of Argyll, Smith gave £1,000 (equivalent to £190,000 in 2023) to Monmouth so that he could hire a ship to sail to Lyme Regis.
