'My Three Sons' big brother Don Grady dies at 68

THOUSAND OAKS, Calif. (AP) — Don Grady, who was one of television's most-beloved big brothers as Robbie Douglas on the long-running 1960s hit "My Three Sons," died Wednesday. He was 68.

His "My Three Sons" co-star Barry Livingston, who played youngest brother Ernie, confirmed Grady's death to The Associated Press. Livingston said Grady had been suffering from cancer and receiving hospice care at his home in Thousand Oaks, Calif. But the exact cause and place of death were not immediately clear.

"It's the oldest cliche in the world when TV brothers start referring to each other like biological brothers, but he was the oldest, and somebody I looked up to and learned from a great deal about life," Livingston said.
