Protestant Exiles from France/Volume 2 - Book Third - Chapter 20 - Gaussen
Gaussen. — The English family of Gaussen of Brookmans Park (as well as a French branch, which was represented by Le Chevalier de Gaussen, who died in 1843) sprang from the Gaussens of Languedoc. Jean Gaussen, a refugee in Geneva in 1685, was married to Marguerite Bosanquet, sister of David Bosanquet. Two of the sons, Pierre and Francois, were refugees in London, and died there, without issue; the former was Treasurer of the French Hospital in 1745, and Deputy-Governor in 1756. But they had a brother, Paul Gaussen, who married Catherine Valat; he lived in Geneva, and died in 1774; his third and fourth sons founded families. Paul Gaussen s fourth son, David Francois Gaussen, remained in Geneva; he was the grandfather of the celebrated pasteur and professor, Francois Samuel Robert Louis Gaussen (born 25th August 1790, died 18th June 1863), author of “La Theopneustie,” and kindred works. Paul Gaussen’s third son, Jean Pierre Gaussen, was adopted by his English refugee uncles, and joined them in London in the year 1739, the sixteenth year of his age. He became Governor of the Bank of England, and a Director of the East India Company. He married his cousin, Anna Maria, daughter of Samuel Bosanquet of Forest House, the second son of David Bosanquet. His son was Colonel Samuel Robert Gaussen, who was High Sheriff of Hertfordshire, and in 1782 a Director of the French Hospital; he married Eliza, daughter of Jacob Bosanquet, Esq. of Broxbournebury, and dying in 1812, was succeeded by the second Samuel-Robert, father of Robert William Gaussen, Esq. of Brookmans Park (born 1814, died 1880). [Harriet, daughter of Colonel S.R. Gaussen, was the wife of Lieut.-Colonel James Best of Park House, near Maidstone, who died on 20th June 1849; she died on 21st January 1875. She was the mother of Mawdistley Gaussen Pest, Esq. of Park House (born 1826); and her daughter, Emily Dorothy, was married on 25th August 1864 to James Whatman Bosanquet, Esq. of Claysmore, Middlesex.]
The Irish family of Gaussen is recognised by Haag as of Huguenot origin; but whether it sprang from the Saumur, the Burgundy, or the Guienne stock is not known. The refugee set sail from France for England, but was driven by a storm into Carlingford Bay, and found shelter for life in Newry. His name was David Gaussen (born 1664, died 1751); he won an Irish bride, Miss Dorothy Fortescue; his son was David of Newry (died 1802); his grandson was David of Ballyronan House, who died in 1832 (his sister, Miss Elizabeth Gaussen, lived to a great age); the refugee’s great-grandson was David of Lakeview House, County Derry (died 1853); his great-great-grandsons were David Campbell Gaussen, Esq. of Shanemullagh (born 1815), barrister-at-law, Captain Thomas Lovett Gaussen, R.N., Rev. Edmond James Gaussen, and William Ash Gaussen, Esq.
