Unless we are referring to the family of, say,
Fred Couples (born October 3, 1959), an American professional golfer and former World No. 1 who competes on the PGA Tour. He has won numerous events, and is most famous for winning the 1992 Masters Tournament.
i have the answer as being 4, i heard or read it somewhere but need it to be clarified for a quiz question that i am setting. good answer re fred couples, lol.
