Caroline d'Aguilar After the death of his first wife on 5 May 1763, d'Aguilar married Rebecca (née Lamego) da Costa on 5 March 1767. She was the daughter of Isaac Lamego, and widow of Benjamin Mendes da Costa, Chairman of the Committee of Diligence (and father of Benjamin Mendes da Costa, Australian merchant). When d'Aguilar took up his eccentric life, however, the couple separated. After twenty years, a partial reconciliation took place between the baron and his wife, but only for a short time. Rebecca died on 30 November 1795. Upon his death at Islington in 1802, d'Aguilar left a fortune valued at £200,000 hidden throughout the dwelling to his two daughters who survived him. Descendants Through his daughter Georgina, he was a grandfather of Leveson Douglas Stewart and James Alexander Stewart (1784–1843), who married Mary Elizabeth Frederica Mackenzie, former wife of Vice Admiral Sir Samuel Hood, daughter of Francis Mackenzie, 1st Baron Seaforth and sister of Helen Anne Mackenzie (wife of Joshua Henry Mackenzie, Lord Mackenzie). After their marriage, he assumed the additional surname of Mackenzie.
