Cubby O’Brien was the second-most-popular Mouseketeer on the original run of the Mickey Mouse Club, after Annette Funicello.
He was one the few Mouseketeers featured in all three seasons (1955-1958) of original programming. He was also the only musician among the Mouseketeers who was permitted to play on-camera.
His real name wasn’t Cubby — it was Carl. “Cubby got his nickname from his mother, who thought he looked like a bear cub as an infant.”
But the public knew him as Cubby, so Cubby is what popped up on the SSA’s baby name list:
- 1959: 5 baby boys named Cubby
- 1958: 8 baby boys named Cubby
- 1957: 10 baby boys named Cubby
- 1956: 6 baby boys named Cubby [debut]
- 1955: unlisted
The baby name Cubby made the list one more time, in 1963, but hasn’t been back since.
