While searching in the Library today I came across an write up about Ballinure House in Blackrock associated with the Perrier family. The following is a quote from a book by Richard Henchion called "East to Mahon". "The Perriers were among the leading civic and commercial families in Cork in the 19century. Thre first into Ireland about 1685 was Mark Du Perrier, a Huguenot from Caen, Brittany fleeing religious persecution in his native land. He settled in Dublin.
In 1776 the family forged a Cork link when Mrs. Anthony Perrier was left a widow with 8 children under twenty. She felt she needed the support of her mother's connections, The Spillers of Ross and the Stawells of Coolmanin and she removed from Dublin to be close to them.
Sir David Perrier (1765-1826) glass manufacturer, sugar refiner, paper maker and distiller who has been considered in connection with the Ballintemple Corporation, was one of Mrs. Perrier's sons. So too was George (1767-1850) who married as his second wife in 1833 Mrs. Deane, who, however, does not appear to have been a connection of Sir. Thomas of Dundanion. So also was Anthony (1770-1845) later Sir Anthon. One of Anthony's 16 children married John Osborne M.D. Lindville Asylum, while his eldest son William Lumley (1805-1895) resided in Ballinure House.
Wm. L. Perrier wiggled his way onto the City Council. He was an Alderman, a J.P and High Sheriff in 1832/3. He stepped into the Insurance business that his father put together making it his life's career. He married in 1831 Anna Lumley of Douglas House who died at Alma Ville, Ballintemple in 1897. They and their daughter lived at Ballinure between 1850 and 1930. They had two sons the second of whom, Wm. Lumley Jnr (1839-1885) took the insurance business into the third generation. The family had the proud motto "Consilio et Vi" (Courtesy and Strength). Wm.Snr was also a director of the Cork and Bandon Rly, Hon Sec and Hon Treas. of Skiddys Almshouse, Shandon Street, a director of the Commercial Blds. on the South Mall and a Borough Magistrate.
Ballinure House was still standing, though unoccupied in 1980. It was a ruin in 1992 and demolished soon after. Some specimens of chestnut, elm, holly, plane, palm and Araucaria better known as Monkey Puzzle or the Norfolk Pine, still survive to remind the passerby of other folk and different times"
The areas listed above are mostly in the Blackrock suburb of Cork City. Some interesting facts there about the Perriers and the motto is interesting.
The fact that the Spillers of Ross, and the Stawells of Coolmain - an area near Kilbrittain Co Cork were relations of Mrs. Anthony Perrier might give you some clue to her relations.
Hope this is some help
