Boxers, who had taken over another boxer's name or parts of it?

Thailand had the Galaxy Twins, Khaosai and Kaokar.

I think there were also some triples or quadruplets with the last name 3K Battery Gym.

 

That was the pr1ck Anthony Small he never fought under that name he had SRCJJ on his shorts.

He's now a member of the Islamic State terror group

 

Pete Q & Eligio Sardiñas Montalvo.

 

Sugar Ray Robinson stole the name of some amateur boxer in his gym

 

Jack Edwards was a British tea planter in Uganda. I think he was like a father figure

 

Beats me why would anyone ever call him that

 

It's ... a joke.

 

Jim Braddock fought under James J. Braddock as an homage to James J. Corbett and James J. Jeffries.

 

Young Jack Johnson.
