From an aristocratic family, Lady Susanna was a staunch, lifelong whig and fervent anti-Jacobite/anti-Tory, taking an active and prominent role in Whig elections and campaigns. In late July 1754 she was implicated in the Rag plot, the new interest's last attempt to smear the old interest with charges of Jacobitism before the election petitions were taken up by parliament. As a known poet and someone who had written and published at least one poem and an address to the voters during the election campaign, she was suspected of having written the notorious pro-Jacobite verses which lay at the heart of the plot. I couldn't find any record in the ESTC, and she's a little outside of our time range, but I thought she was a super interesting case of a woman-poet in the political eye.
