a sitcom about a widower (Fred MacMurray) raising a trio of boys (hence

run, MacMurray decided to adopt a friend of his son Chip's after the
boy's parents died in a car accident. The kid's name was Ernie and he

concept alive after the eldest, Mike, was written out of the show.

real-life brother of Steve Livingston, the actor who played Chip. After
"My Three Sons" ended its run in 1972, what became of the boy we knew
