Castle ffrench is said to have been built c.1779 by Charles Ffrench, then Mayor of Galway. Wilson, in 1786, in one instance refers to "Clougher" as the seat of Mr. French but in a later reference notes Castle-French as "the fine seat of Sir Thomas French". In 1814 and again in 1837 it is recorded as the residence of Lord French. In 1856 it was occupied by James Thorngate when it was valued at £40. It is still extant and occupied and in 2006 was offered for sale.
