The Negro family can be traced back to cave dwellers in Southern France during the Neaderthal period (pre Aussie Rules). More recently (753 BCE) the name appears in the city of Ferrara in Southern Italy and one of the first records is from 929, the bishop Carlo Negri di Pietra Santa. Fred denies this but only because he can't pronounce the name and he hates the Church.
For actual factual check out Fredipedia.
The Negros are an industrious family. Fred's brother Dez, also a renowned singer, had a fence building company; Negro Erections P/L. Fred spent many happy hours using his hands but it had nothing to do with this business.
Fred is not paid by Kellogs and has never been a Victorian Police officer.
