MEMOIR OF JOSEPH SHERIDAN LE FANU.
A noble Huguenot family, owning considerable property in Normandy, the Le Fanus of Caen, were, upon the revocation of the Edict of Nantes, deprived of their ancestral estates of Mandeville, Sequeville, and Cresseron; but, owing to their possessing influential relatives at the court of Louis the Fourteenth, were allowed to quit their country for England, unmolested, with their personal property. We meet with John Le Fanu de Sequeville and Charles Le Fanu de Cresseron, as cavalry officers in William the Third's army; Charles being so distinguished a member of the King's staff that he was presented with William's portrait from his master's own hand. He afterwards served as a major of dragoons under Marlborough.
At the beginning of the eighteenth century, William Le Fanu was the sole survivor of his family. He married Henrietta Raboteau de Puggibaut, the last of another great and noble Huguenot family, whose escape from France, as a child, by the aid of a Roman Catholic uncle in high position at the French court, was effected after adventures of the most romantic danger.
Joseph Le Fanu, the eldest of the sons of this marriage who left issue, held the office of Clerk of the Coast in Ireland. He married for the second time Alicia, daughter of Thomas Sheridan and sister of Richard Brinsley Sheridan; his brother, Captain Henry Le Fanu, of Leamington, being united to the only other sister of the great wit and orator.
