Protestant Exiles from France/Volume 2 - Book Third - Chapter 20 - Gervais
Gervais. — The Irish family of Gervais of Cecil descends from Jean Gervais of Tournon, in Guienne, and Anne Fabre, his wife, who both died before the Revocation. Their sons, Pierre and Daniel, were brought to England in 1685 by an uncle. Daniel (born 1679) became a Captain in the army, and Gentleman-Usher to the Queen; he married Pauline, daughter of the Rev. Mr. Balaguier of the French Protestant Church, Dublin. Pierre Gervais (born 1677, died 1730) married in 1717 Marie Francoise Girard; his son was Peter (born 1722, died 1800), who married Elizabeth, daughter of Rev. Samuel Close of Elm Park, county Armagh. Their son, Rev. Francis Gervais (died 1849), was the proprietor of the estate of Cecil, in county Tyrone; his wife was Katherine Jane, daughter of Michael Tisdall, Esq., and his heir and successor was Francis John Gervais, Esq. of Cecil, M.A. (born 21st August 1819, died 19th July 1882.) The latter is represented (I presume) by his son, Francis Peter Gervais, Esq. (born 12th December 1868).
