Ephraim Lópes Pereira d'Aguilar (1739 in Vienna – 1802 in London) was the second Baron d'Aguilar, a Barony of the Holy Roman Empire. Early life He was a son of Donna Simha da Fonseca, who died 1755, and Baron Diego Pereira d'Aguilar, a Jewish businessman, community leader and philanthropist, originally a Portuguese converso. In 1757, d'Aguilar was naturalized in England, where he had settled with his father. Career He succeeded to his father's title and fortune upon his death on 10 August 1759 in London, and for a time lived in luxurious style with twenty servants at the Broad Street Buildings. By the time of the American Revolutionary War, however, d'Aguilar had lost an American estate of 15,000 acres (61 km²). Subsequently, he became known as a miserly and eccentric person, giving up his mansion in Broad Street as well as his country houses at Bethnal Green, Twickenham, and Sydenham. His establishment at Colebrook Row, Islington, was popularly styled "Starvation Farm", because of the scanty food provided for the cattle. He came a freemason in 1778. Public offices D'Aguilar held various positions in his community, and served as treasurer of the Portuguese Synagogue; the minutes of the proceedings of the Mahamad bear the signature of Ephraim d'Aguilar. He was elected warden in 1765, but declined to serve, and refused on technical grounds to pay the fine. D'Aguilar was given eight days to accept the position or to submit to the penalty. He evidently submitted, since on 5 March 1767 he married for the second time. He would not have been able to marry her had he been lying under the ban. d'Aguilar was again elected to office in 1770, and for some years thereafter remained a member of the synagogue. Personal life On 8 December 1756, he married Simha "Sarah" Mendes da Costa (–1763), daughter of Moses Mendes da Costa and Catherine da Costa, who is reported to have brought him a fortune of £150,000. She was the mother of his two legitimate daughters. He also had a son. His children included: Georgina Isabella d'Aguilar, who married Vice Admiral The Hon. Keith Stewart (1739–1795), a son of Alexander Stewart, 6th Earl of Galloway and the former Lady Catherine Cochrane (the youngest daughter of John Cochrane, 4th Earl of Dundonald). Following his death, she married secondly, in 1797, Lt.-Col. Richard Fitzgerald, who was killed in action at the Battle of Waterloo.
