An ancient French family, surnamed Chevalleau, acquired the territorial title of De la Liffardière, and at a later date the territorial title of De Boisragon. Jean Chevalleau, Ecuyer, proved his chevalerie in 1594. In 1614, Pierre Chevalleau, Ecuyer, Seigneur de la Liffardière, married Marthe, daughter of Jean Rignon, Ecuyer, Sieur de la Braconniere by Antoinette Prevost. His son and heir, Jean Chevalleau, Ecuyer, Seigneur de Boisragon, was living in the chateau of St. Maixant in Poitou, in 1665, having married, in 1652, Catherine de Marconnare. From him descended the French family and the refugee family of Boisragon.
The refugee, born in Maixant, was the younger son of Louis Chevalleau, Seigneur de Boisragon. He took refuge, first in Holland, and latterly in England in the train of William of Orange. On 18th March 1689-90, he was enrolled in Schomberg’s Horse as a cornet; he rose to be Captain in that regiment. He obtained the rank of Major in 1708, and was Brevet-Lieut.-Colonel in 1709-10. At the date of his death he was Lieut.-Colonel in command of the 53d Foot. His Will, dated 16th December 1729, was proved 2d April 1730.
He had married, in 1700, Louise Poyrand, daughter of Messire Rene Poyrand, Seigneur Des Clouseaux, by whom he had a daughter, Catherine Louisa, and a son, Alexander Louis Chevalleau de Boisragon, who, after serving as an ensign in our army, retired to Surinam. Lieutenant-Colonel De Boisragon’s second wife, whom he married on 21st December 1713, was Marie Henriette, daughter of Messire Nicolas de Rambouillet, chevalier, Seigneur de la Sablière. By her he had Susanna Henrietta, Mrs. Layard — Elizabeth, Mrs. Maty — and Anne, Mrs. Justamond — also Major Henry Boisragon of Windsor, who died in 1791, and Major Charles Gideon Boisragon, C.B.
The latter Major Boisragon married Mary, daughter of James Patterson ot Combe, County Down. His son was Henry Charles Boisragon, M.D., of Cheltenham, who married, on 7th June 1803, Mary, daughter of John Gascoyne Fanshawe of Parsloe, Essex, and whose sons were Captain Charles Henry Boisragon of the Bengal army, Theodore Smith Boisragon, M.D., and Conrad Gascoyne Boisragon. The eldest of the above, Captain Boisragon (born in 1804) married Ellen, daughter of General Maxwell, and his sons were Lieutenant-Colonel Henry Boisragon, and Major- General Theodore Walter Ross Boisragon, C.B., commandant of the 30th Punjab Infantry from 1861 to 1881, who died in 1882.
