Major-General Sir Guy Campbell, 1st Baronet, was a British Army officer, the eldest son of Lieutenant-General Colin Campbell and his wife Mary, daughter of Guy Johnson. His branch of the Campbell baronets is referred to as St Cross Mede.

Lord Edward FitzGerald was an Irish aristocrat and nationalist. He abandoned his prospects as a distinguished veteran of British service in the American War of Independence, and as an Irish Parliamentarian, to embrace the cause of an independent Irish republic. Unable to reconcile with Ireland's Protestant Ascendancy or with the Kingdom's English-appointed administration, he sought inspiration in revolutionary France where, in 1792, he met and befriended Thomas Paine. From 1796 he became a leading proponent within the Society of United Irishmen of a French-assisted insurrection. On the eve of the intended uprising in May 1798, he was fatally wounded in the course of arrest.
