English pet form of Isaac. It was made famous in the 20th century as the nickname of the American general and president Dwight D. Eisenhower (1890–1969), although in this case, of course, it was based on his surname.
English (mainly southern): from the Old French habitational name and personal name Paris (see Paris 1). Parrish is the most common form of the name in English, and is the result of confusion between -s and -sh (compare Norris), reinforced by folk etymological association with the modern English word parish. In the 17th and 18th centuries the surname was occasionally bestowed on foundlings brought up at the expense of the parish.
