Protestant Exiles from France/Volume 2 - Book Third - Chapter 20 - Delacherois
Delacherois. — This family descends from Samuel la Cherois (see chap, xiii.), only son of Major Nicholas de la Cherois, by Marie Crommelin, sister of the Royal Overseer of the Linen Manufacture. He married in 1734 Sara Cornière, daughter of Daniel Cornière and Sara de Lalande, and his eldest son was Daniel de la Cherois. Daniel’s marriage in 1782 was another tie to the Crommelins, his wife being Mary, daughter of Alexander Crommelin, granddaughter of Samuel Louis Crommelin, junr.; great-granddaughter of Samuel Louis, brother of the celebrated Louis Crommelin. The Major did not make any fortune to retrieve his losses as a refugee. But (as already narrated) his elder brother Daniel, Governor of Pondicherry, acquired great wealth; and Daniel’s only child and heiress, the Dowager-Countess of Mount-Alexander, succeeded by Will to the Earl of Mount-Alexander’s landed estates in County Down. These she divided into two shares, one of which became the property of the eldest surviving son of Daniel De la Cherois and Mary Crommelin. Three sons had sprung from this marriage, of whom the youngest, Ensign Nicholas De la Cherois of the 47th, was killed at Barossa in 1811; the eldest, Daniel of Donaghadee (born 1783, died 1850) was unmarried; thus the representation of the family devolved on the descendants of the second son, Samuel Louis (died 1836). The present head of the family is Nicholas De la Cherois, Esq. of Ballywilliam, County Down (born 1821), late of the 7th Dragoon Guards. The second family is presided over by Daniel De la Cherois, Esq. of the Manor House, Donaghadee (born 1825), M.A. of Dublin, and a member of the Irish Bar; his heir is Daniel Louis (born 1855).
