Freddy died at the age of 42 in 1981 due to complications from alcoholism. He was considered a black sheep of the family for not taking an interest in the family's real-estate business.

Freddy died at the age of 42 in 1981 due to complications from alcoholism. He was considered a black sheep of the family for not taking an interest in the family's real-estate business.

When Fred Trump Sr. died in 1999, Mary Trump and her brother contested his will, which left them a substantially smaller inheritance than the other Trump grandchildren.

Donald Trump responded by cutting them off the family's medical insurance plan. It was a tough blow for Fred III, who had just welcomed a baby with serious health issues.

Mary Trump bashed the decision to cut the medical benefits in an interview with the New York Daily News in December 2000, saying her "aunt and uncles should be ashamed of themselves."
