Miss Owenson entered the household of John Hamilton, 1st Marquess of Abercorn, and in 1812 — persuaded by Lady Abercorn, the former Lady Anne Jane Gore — she married the philosopher and surgeon to the household, Sir Thomas Charles Morgan, but books continued to flow from her facile pen. She was several years his senior. They married in January 1812, and she was henceforth known as Lady Morgan. After their marriage the couple lived in Barons Court, the Abercorn seat, before eventually moving to Dublin. Thomas Morgan died in London on 28 August 1843.
